World's tallest passive house tower could rise in Vancouver's West End

Canadian company Henson Developments is planning the world’s tallest passive house for downtown Vancouver. Slated for the edge of the city's West End neighborhood, 1075 Nelson would stand 60 stories tall, hovering higher than most towers in British Columbia and with three times the efficiency.  The Vancouver Courier reported that the City of Vancouver is currently reviewing Henson’s rezoning application and after that, it will go before the city council for a public hearing. Sean Pander, who serves as the city’s green building manager, believes the 555-foot-tall project will push other developers to pursue more eco-friendly projects. It’s located in a vibrant, largely residential part of town where there is rapid growth. “What makes it a really big deal is the amount of attention it will get with the public, as well as with developers, designers, manufacturers of windows,” said Pander in an interview with the Courier.   But Rick Gregory, vice-president of Henson Developments, isn’t looking to build a basic, boxy tower with an ultra-tight envelope, he said. Both of the two top tallest passive house buildings in the world are rather square: Bolueta by VArquitectors in Bilbao, Spain, and the 250-foot tall residential structure by Handel Architects at Cornell Tech. Gregory wanted 1075 Nelson to be architecturally-significant. “There is a certain look that Passive House generally yields and we’re trying to move away from that to make it much more attractive to other people to take the same approach," he told the Courier. To achieve this, Gregory enlisted the help of British architect Tom Wright of WKK Architects and Gwyn Vose, director of IBI Group. Early renderings reveal an undulating structure with large loggia spaces in the center voids spanning multiple floors. While it’s likely Henson Developments will get support for some sort of passive house construction—Vancouver released its own zero-emissions building plan in 2016—Gregory's goal of building an atypical design that’s the tallest in the world could prove more difficult if it ultimately means more money spent.

César Pelli, Argentine architect of the modern skyscraper, dies at age 92

Argentine architect César Pelli passed away on Friday at his home in New Haven, Connecticut, according to a state news agency and government officials. He was 92 years old.  The award-winning architect was responsible for designing some of the most famous skyscrapers in the world, including the Petronas Towers in Kuala Lumpur, Malaysia, The Landmark in Abu Dhabi, the recently completed Salesforce Tower, and the first phase of the adjacent Transbay Transit Center, both in San Francisco. While Pelli was largely known later in his career for his innovative glass towers, his earlier years in architecture were majorly influenced by who he worked with and where he lived.  Born October 12, 1926, in San Miguel de Tucumán, Argentina, Pelli completed his undergraduate architectural studies at the Universidad Nacional de Tucumán. After briefly working in the country, Pelli moved to the United States in 1952 to pursue his masters at the University of Illinois School of Architecture. From there, he worked in Michigan under Eero Saarinen for a decade, designing small pieces on projects such as the TWA Terminal at John F. Kennedy Airport.  Before starting his eponymous firm Cesar Pelli & Associates in 1984, Pelli held leadership positions at Daniel, Mann, Johnson, and Mendenhall and Gruen Associates in Los Angeles. At the latter firm, he designed his seminal Pacific Design Center in West Hollywood, the all-glass, 1,600,000-square-foot facility known as the “Blue Whale.” In 1977, Pelli began his 12-year tenure as dean at the Yale School of Architecture in New Haven, where he continued to live until his death.  Seven years into his deanship, Pelli received the commission for the 1984 expansion and renovation of the Museum of Modern Art in New York, which, according to the New York Times, forced him to open his firm. He then went on design the World Financial Center and Winter Garden (now known as Brookfield Place) in Lower Manhattan, additional terminals for the Ronald Reagan National Airport in Washington, D.C., and scores of towers in London, Hong Kong, Buenos Aires, and Jersey City, among other global cities.  In 2005, Pelli renamed his studio to Pelli Clarke Pelli Architects, giving credit to his long-time partner Fred Clarke and son Rafael, who assumed a large role in the company. His wife, Diana Balmori, was a landscape architect, urban designer, and a partner on his team as well. She passed away in 2016. They are survived by another son, Denis, and two grandchildren.  Though Pelli didn’t open his firm until age 50, the impact he made on architecture within the last four decades of his life was widespread. He designed hundreds of buildings and was awarded just as many times for his efforts. Pelli received the profession’s highest honor, the AIA Gold Medal, in 1995.   In response to Pelli's passing, Robert Ivy, chief executive officer of the AIA, provided the following statement: “César Pelli was a consummate architect, teacher, and mentor. Rooted both in the creative legacy of Eero Saarinen and the pragmatic leaders of west coast development, César transformed skylines around the world and influenced the modern city as we know it. A master of both the urban scale and the carefully conceived individual detail, he leaves a legacy that stands as tall as the buildings he designed and as rich as the lives of the many architects whose careers were shaped by his generous teaching.”

Detroit's upcoming tallest tower teeters on final decision of total height

Downtown Detroit is slated to build one of the tallest buildings in the Midwest, set over the former footprint of the city’s iconic J.L. Hudson department store. Though construction on the project has already begun, the exact height of the soaring structure remains unresolved. Crain’s Detroit Business reported that the $909-million mixed-use tower planned for the long-vacant Hudson site could reach as high as 912 feet—an increase of over 100 feet from previous estimates. But the developers won’t make a final decision on its height until the end of January. This is the third time Bedrock LLC, owned by Quicken Loans founder Dan Gilbert, has increased its estimated elevation and updated the design. The complex is being designed by Detroit-based Hamilton Anderson Associates and SHoP Architects. Though the skyscraper won’t make the list of top 10 tallest towers in the country, it will break the record for the largest high-rise in the Motor City. As of now, the design shows the tower next to a nine-story podium connected by a public plaza and alleyway. It’s anticipated to include programming for residential space, and potentially room for hotel or commercial use. The additional 112 feet of height would allow the architects more flexibility in designing the building's various programs, according to Crain’s. Per the current designs, that number coincides with the established length of the elevator core.   The project was first announced in February 2017 with the tower reaching a maximum height of 734 feet. It was projected to feature space for retail and restaurants, events and conferences, offices and exhibits, as well as residential units. A public observation deck and an underground parking garage were also cited in the initial plans. Current renderings reveal two glass-clad, boxy constructions with outdoor terraces and greenspace. The project is estimated to take four-to-five years to complete. Demolition of the existing parking garage on site is nearly finished and foundation work is already underway.

Zaha Hadid's Nile Tower, the tallest building in Africa, will rise in Cairo

Zaha Hadid Architects’ design for Africa's tallest tower is reportedly breaking ground after nearly a decade of delays by the Egyptian government, according to Forbes. The 70-story Nile Tower will rise along the Nile River in central Cairo as part of an upscale new downtown district. The project is expected to spur growth and investment in a previously neglected area that currently houses middle-class and low-income residents. The 1.3 million-square-foot Nile Tower was first envisioned by the late Hadid in 2007 and so far, design details haven’t changed. The rectangular structure will house residential and hotel components inside a thin, twisting volume. Apartments will be built out on the top 36 floors with views of the nearby pyramids, while the middle 18 floors will include a hotel with 230 rooms. Other floors will feature a casino, nightclub, spa, health club, and shops.  The luxury property is set to be marketed toward higher-income tenants, who in recent years have moved to the outskirts of Cairo into newer developments. Nile Tower will be a focal point of the aforementioned upcoming neighborhood that its developers hope will spark an influx of wealthy residents back into downtown Cairo. Zaha Hadid Architects isn’t the only starchitect firm set to build in the planned district. Foster + Partners designed a mixed-use project for the site as well, which will go atop a recently-demolished lower-income housing complex in the neighboring Maspero Triangle. Critics of both projects say the displacement of Cairo’s poorest and most vulnerable people is already a huge issue. Apart from its controversial setting, one major reason for the Nile Tower’s postponement was the national shake-up Egypt experienced in 2011 when its long-time president Hosni Mubarak was removed from office and tried for corruption and abuse. Mubarak was an avid supporter of the Nile Tower and the plans for creating an upscale new residential and business district. The country couldn’t get it back on track amidst all the political and economic unrest. Under Egypt's current president, Abdel Fattah al-Sisi, the project is once again a top priority for the country as well as for Cairo’s development. Ashraf El Tanani, president of the site's developer Living In Interiors, told Forbes that President Sisi’s government is actively involved in getting the height clearance for the project as well as making it a financially viable project. As of now, the tower will cost $600 million, though it’s likely to rise by $150 million due to the weak Egyptian pound which is making building materials much more expensive than planned. Despite the hefty price tag, the project is expected to make a significant return for the domestic economy with increased construction jobs, as well as its potential for enhancing the housing and tourism sectors once complete. The groundbreaking has been set for the near future, but no date has been officially named.

Pyongyang’s giant pyramid puts on a massive light show

A video released by Facebook page North Korea Girls 북조선녀성 reveals that an enormous LED light wall that has been added to the massive pyramidal Ryugyong Hotel in Pyongyang, North Korea. In the minute-long video posted Monday, seemingly taken from a car passing by the hotel, the facade of the hotel was lit with flashing animations of lotus flowers, ornate landscapes, spinning lights, and ending with a political statue standing in front of a backdrop of colorful fireworks. The social media page North Korea Girls is a community in Pyongyang, Korea. Affiliated with the website friend.com.kp, the page delivers anonymous pictures, videos, and news from North Korea with English-language narratives. Reports from various sources earlier this year say that the LED display was only added to a portion of the structure. The North Korean government is not readily open to foreign journalists, and whatever video has been made publicly available has likely passed through government censors, presumably for boosterism purposes. The 105-floor Pyongyang skyscraper has been empty since its groundbreaking more than 30 years ago in 1986. As Huffington Post reported, it is “the world’s tallest unoccupied building," and has been, “plagued by engineering problems (including crooked elevator shafts) and a lack of funding.” The post-modern, pyramidal structure was supposed to host “restaurants, offices, and hotel rooms.” It remains unclear whether or not the North Korean government is determined to complete its construction in the near future.

Mexico City's tallest skyscraper by Foster + Partners to begin construction after delays

Construction is set to begin on Reforma 432, a Foster + Partners-designed skyscraper in the heart of Mexico City that’s been snared by setbacks since 2011. According to a 2014 Foster + Partners description that pegged the tower at 866 feet tall, the Reforma 432 will dwarf the city’s current tallest building, the 807-foot-tall Torre Reforma. As first reported by Mexico News Daily, Mexican developer Abilia recently released a statement revealing that construction on Reforma 432 would begin soon and that the mixed-use tower would be split between luxury office space and commercial use. It’s certainly not an even split, with nearly 280,000 square feet set aside for offices and the remaining 20,000 square feet dedicated towards retail. Abilia’s owner, the billionaire businesswoman María Asunción Aramburuzabala, also announced that the updated scheme would be 57 stories tall, three more than Foster + Partners had originally described. Reforma 432 was first proposed in 2011 as the Sky Tower under developer Grupo Elipse, but seemed to have stalled out indefinitely until Aramburuzabala stepped in to take over the project. Located at the intersections between Paseo de La Reforma and Avenida Sevilla, Reforma 432 will sit on an L-shaped site directly opposite La Diana fountain, a city monument. Foster’s design for the tower is heavily striated, and two central vertical bands will run up the western and eastern sides of the facade. The building’s core will be set back towards the smaller portion of the L shaped-site, increasing the size of the floor plates in the larger section of the site. From the renderings, it also appears that the tower will carve out a story for communal outdoor space in the middle of the office floors. Covered, cantilevering terraces jutting from Reforma 432’s first four stories will hold retail components, restaurants, and cafes, while a bank, drop-off area, and entrances to both the offices and the commercial areas will be on the ground floor. This area will be intentionally left open as a publicly accessible plaza that bleeds into the surrounding streetscape. Foster + Partners is no stranger to building in Mexico City, as the British firm has teamed up with Mexican architect Fernando Romero to tackle the city’s new $9.2 billion airport, currently under construction. No start or completion dates for Reforma 432 have been announced as of yet.

Oakland's tallest tower is on the way

A new project under development by Oakland, California–based Lowney Architecture and developer Pinnacle RED aims to bring the East Bay its newest—and tallest—mixed-use tower. The forthcoming 36-story tower will be located at 1261 Harrison Street and will bring 185 apartment units, 120,000 square feet of Class A office space, and 12,000 square feet of commercial uses to downtown Oakland, potentially transforming that city’s downtown Chinatown neighborhood. The 440-foot tower is billed as the city’s only mixed-use tower under development that combines commercial functions with affordable and market-rate housing under one roof. The arrangement is a by-product of the development’s utilization of a density bonus, which allows the developer to build taller and more densely in exchange for providing affordable housing units on-site.  The complex will be anchored on the ground floor by a market hall–style food court with a “locavore” focus. The tower is designed along the street to match the massing and “neighborhood rhythm” of surrounding commercial storefronts, according to Ken Lowney, principal at Lowney Architecture. The 11 floors above street level will be occupied by office spaces with the uppermost levels containing condominiums and maisonettes. Lowney told The Architect’s Newspaper that the lower level will house community-serving establishments that could potentially include current retail tenants occupying an existing commercial structure on the site that will give way to the development. Under the potential plan, a local bicycle shop will return to manage the building’s 185-stall bicycle parking facilities, for example. The project provides an automated 185-stall underground garage, though parking is not required for the site. The gridded glass tower complex grows from its contextual base in a canted fashion, splitting into two alternating masses as it rises up. The tower’s bifurcated facades are wrapped in a gridded frame that extends the depth of the building’s curtain walls out from each facade. The non-structural application of these gridded frames is a leftover from earlier design iterations that called for an externally-structured tower. Instead, the building is held up by internal beams and columns, a shear core, and moment frames. The glass panels that infill these frames are decorated with multicolored metal panels that are designed to reference surrounding conditions, with warmer, brick-like tones coloring lower levels and clear-blue panels populating the uppermost sections of the tower. In a statement, Mark Donahue of Lowney Architecture said,“We strove for a distinctive design by breaking up the building’s mass so that it appears as two towers, but is really one structure,” adding that the tower was designed to “match the façades of nearby, character-rich buildings.” The development is currently undergoing planning approval. 1261 Harrison Street is expected to take roughly two years to complete once plans are approved.

Architect falls to his death from Midtown tower

Architect Bruno Travalja, of Ridgewood, New Jersey, died on Thursday afternoon after falling from the 48th floor of a Midtown Manhattan skyscraper at 6th Avenue and 52nd St. According to the New York Daily News, he bent down to take a measurement and got dizzy when he stood up. He was wearing a safety harness but it wasn't attached to anything, so the co-owner of Crowne Architectural Systems tumbled over the 18-inch security barrier. The Department of Buildings has launched an ongoing investigation. The residential tower was located at 135 52nd Street, between 7th and 6th Avenues.

Queens’s first supertall skyscraper set to break ground in 2017

Queens looks to be in line for it's first supertall skyscraper, situated on 23-15 44th Drive in Long Island City. Rising to 984 feet, the building will house 774 luxury apartment units inside 78 stories, as well as just under 20,000 square feet of retail and commercial space and 225 parking spots, located between the basement and second floor. New York practice Goldstein, Hill & West Architects are behind the project, which totals 969,000 square feet. With Midtown Manhattan less than five minutes away (by car/subway), the tower, known by its official name as "City View Tower," is in a prime location. Neighboring upmarket restaurants, the building is also joined by nearby Gantry State Park (which features a riverside esplanade, a fishing pier, and a playgrounds), and a host of art galleries, notably the MoMA PS1 and Sculpture Center. Other transportation links include walkable access to the East River Ferry and the Long Island Rail Road. Originally, development firm United Construction and Development had planned for a 963-foot tower, however, a 21 foot increase allows the skyscraper to be classified as a "supertall" due it being 300 meters (984 feet) or over. Due to a site elevation of 16 feet, the building will reach a height of 1,000 feet above sea level, and the project has to submit a request to the Federal Aviation Administration for approval to build. According to New York Yimby, plans are also progressing through the Department of Buildings with few alterations being made over the past couple of months. That said, they report a supposed increase of 114 from the planned 660 housing units listed on the developer's page. Ground is set to break on the project at some point next year with completion penned for 2019. Goldstein, Hill & West Architects also have another luxury tower in the making for the area. Located on 42-12 on 28th Street in Long Island City, the tower will be smaller than their "City View Tower" accommodating only 477 units, reaching 634 foot. Amenities are set to include a resident lounge, pool house, full spa and observation deck.

Garden City, Mega City at the Skyscraper Museum

On view until Sept. 4 at the Skyscraper Museum, GARDEN CITY | MEGA CITY showcases the built and unbuilt works of Singapore-based WOHA, an architecture firm that specializes in designing for the world's tropical urban areas. The exhibition begins by contextualizing WOHA's projects with what might be architects' and urbanists' greatest 21st century challenge: the rapidly (and sometimes haphazardly) growing cities of the developing world. 7 of the world's 20 megacities are in tropical areas. So what valuable lessons do WOHA's skyscrapers—designed for density, verticality, heat, and humidity—bring to the table? The exhibition—which consists of ~10 large-scale models shown alongside renderings—argues that it's time to leave the hermetically-sealed modernist tower behind in favor of a more nuanced approach to the building envelope. One built project in particular, a Singaporean public housing project called SkyVille@Dawson (2007-2015), stands out as an exemplar. Its 500-foot-tall towers are diamond-shaped in plan but only one apartment thick at their edges. This leaves a large hollow interior the runs the entire height of each tower; these capacious vertical voids channel cooling breezes and shelter communal green spaces located every 12 floors. Shared spaces, greenery, and passive ventilation are work harmoniously. The Met, a 755-foot-tall tower in Bangkok, makes similarly smart use of natural cooling with a hollow interior open to breezes. Other WOHA projects are verdant, though in a far more luxurious sense. The PARKROYAL on Pickering, for instance, is a hotel and office building in Singapore's Central Business district. Its sculptural concrete forms are brimming with lush vegetation. The other projects fill a similar pattern: large, open, green spaces punctuate the skyscrapers' height. Sometimes massive volumes are removed from the tower to create multiple courtyards in the sky; it's almost as if several medium-height towers with a street-level plaza were stacked atop each other (see the Oasia Downtown, at far bottom). While it's doubtful these latter-day Babylonian gardens are open to the public in most instances, and the proliferation of greenery recalls a broader fad of trees-on-towers, there's no pretension that this architecture is shovel-ready to replace the informal settlements or slums of the world's growing cities. In the words of the exhibition text, "WOHA thinks of their prototypes as components for a fully sustainable future city....Cities must now be made of, by and for people..." and not just "vast agglomerations of inanimate stand-along financial equation." The firm even rated each of its projects in terms of a "Civic Generosity Index," with some projects earning lower marks than others. With luck, projects like Skyville@Dawson will stand as inspiration for when we start designing and planning tropical megalopolises in earnest. It makes perfect sense that Singapore would be the locus for this urban innovation—the tiny island already supplies its own water even as the rest of the world prepares for a coming freshwater crises. With over 80% of Singaporeans living in public housing, the Singaporean government has long been committed to smartly designing for density: necessity is the mother of invention when 5.5 million people need to comfortably live on 277 square miles of land. If anything, after seeing these projects, the Buckminster Fuller in me wanted more (as Bucky would say) "synergy": skyscrapers that not only channel cooling breezes, but also capture rainwater for their residents or even use vegetation and gravity to filter gray water. With greater luck, firms like WOHA will continue to capitalize on the unique circumstances of Singapore to experiment, then transport that knowledge to other cities in the tropics (and perhaps beyond). While this exhibition doesn't show how these towers work in relation to their cities—this is a show for architects, less for urbanists, though design at this scale is practically urban—perhaps WOHA will elaborate on that issue during their next exhibition: Fragments of an Urban Future, which will be at the Palazza Bembo of the 2016 Venice Architecture Biennale. The exhibit will, according to a press release, respond to "the most pressing issues facing megacities today— unprecedented urbanization, accelerating climate change, and the need for preservation of tropical biodiversity." For those interested, you can explore the GARDEN CITY | MEGA CITY  exhibition here on the Skyscraper Museum's website.

Timber skyscraper imagined at the heart of London's brutalist Barbican

Designed by architects Chamberlin, Powell and Bon after the Blitz destroyed most of the site, the Barbican estate is now Grade II listed (part of a statutory list of buildings of special Architectural or historic interest). As a result, the area has become synonymous with concrete, being a famed brutalist site. PLP Architecture and the University of Cambridge, however, have different ideas. They're proposing a 984-foot wooden skyscraper, the city's first, at the center of the estate. The skyscraper, according to PLP, is merely for "research." Despite this, the firm said that they had presented the idea to current London Mayor Boris Johnson and said that his response was "positive." The Mayor also commented that natural materials like wood are currently “vastly underused.” Already, the timber tower has been dubbed the "Toothpick" by The Architect's Journal, such is the way of nicknaming skyscrapers in London, already home to the "Walkie-talkie," the "Gherkin," and the "Cheesegrater." Despite its radical change in materiality, the Toothpick aligns with the Barbican's original plan of providing housing at the center of the city, overseeing the creation of 1,000 new living units. Despite being slimmer than the iconic 42 story (404 feet) Cromwell, Shakespeare, and Lauderdale Towers, the wooden skyscraper would almost be double their height at 80 stories high. This would make it the city's second tallest building, second only to Renzo Piano's Shard. As for the towers environmental impact, the Toothpick would "lock-in 50,000 tonnes of CO2 in the building timber frame, equivalent to the annual CO2 emissions of 5,000 Londoners." The project is in collaboration with the University of Cambridge and Smith and Wallwork Engineers. Dr Michael Ramage, Director of Cambridges Centre for Natural Material Innovation, said: "The Barbican was designed in the middle of the last century to bring residential living into the city of London—and it was successful. We've put our proposals on the Barbican as a way to imagine what the future of construction could look like in the 21st century." "We now live predominantly in cities and so the proposals have been designed to improve our wellbeing in an urban context," added Kevin Flanagan, Partner at PLP Architecture. "Timber buildings have the potential architecturally to create a more pleasing, relaxed, sociable and creative urban experience. Our firm is currently designing many of Londons tall buildings, and the use of timber could transform the way we build in this city." When asked if PLP would be presenting the "research" to the next Mayor of London, their response was: "it depends who the mayor is!" https://www.youtube.com/watch?v=vLPlJsoVq8k

Helmut Jahn's latest Chicago skyscraper loses 200 feet in height

Dubbed “1000M” for its 1000 South Michigan Avenue address, New York developers Time Equities (who also partnered with Jahn on a New York City tower bearing close resemblance) and JK Equities lopped nearly 200 feet off the plan, bringing the height to 832 feet with 73 stories. It conforms to new height guidelines that govern the south portion of the Historic Michigan Boulevard District, which runs from Randolph Street to 11th Street, and assuages residents’ concerns over the appropriateness of dropping a supertall on an iconic streetwall. The amendment from the Commission on Chicago Landmarks allows for new towers up to 900 feet on Michigan and Wabash Avenues between 8th and 11th Streets.

In the process, a staggered stacked cube concept was scrapped, replaced by sinuous curves and triangular planes. Project text attributes the “hard sloping north edge, the soft and natural southeast corner, and curved east and west faces” to the textures of city, lake, and park, respectively. A decidedly rectangular base transitions to parallelogram from the 24 through 72 floors, allowing the tower’s top-heavy dimensions to develop slowly and gracefully. An enclosed omni-directional top houses mechanicals and a 5,300-square-foot roof terrace. Among Chicago’s tallest towers, Jahn said at the community presentation, this “is the only building to get bigger toward the top." The shift from rectilinear base to more curvaceous top also delineates the change from apartments to condos in the tower. One hundred and forty rental units would fill the base, providing an aesthetic screen for ten floors of parking. An amenity level divides these lower rental units from the 366 condos planned for the upper floors, while external load bearing “super columns” also signal this break on the tower’s facade. Architecture critic Blair Kamin noted in the Chicago Tribune that the historic district’s tallest structure is the 430-foot-tall Metropolitan Tower several blocks north. Immediate Michigan Avenue neighbors are 100- and 272-feet-tall, the shorter of which was acquired by the developers. Clearly, the pose struck by Jahn’s tower will be instrumental to its contextual success or failure. To that end, the tower’s shape is derived largely from its relationship to adjoining buildings. The taller north neighbor’s setback is matched and a 20-foot gap exceeds the 12 feet required by code, preserving greater sunlight and airflow for that building’s south-facing tenants. A sloping 17-foot outcrop hovers over the southern neighbor, in a way cradling it (the outcropping and expansion of floor plates also helps with the economics of a shortened proposal). In material terms, a metal facade system transitions to a greater ratio of glass once the tower clears its neighbors. Community reaction to the new concept has been overwhelmingly positive, but a lingering concern is whether equal care will be given to the less prominent west facade. Relative stature may be diminished, but Jahn’s redesign still sets out to create a visual counterpoint to the wall of skyscrapers rounding Michigan onto Randolph. Together with Rafael Viñoly’s twin 76-story tower designs at Michigan Avenue and Roosevelt Road and Hartshorne Plunkard Architecture’s rendering of a 585-foot-tall apartment building two blocks north of 1000M, a bolder definition of Grant Park’s south rim is on the way. Developers hope to break ground in 12 to 15 months.
