The Pacific Pointe development, designed by David Baker Architects (DBA) with Interstice Architects as associate and landscape architects, is the first 100-percent-affordable housing development in the new Hunters View area of San Francisco. The development is among the first completed projects in the new 420-acre neighborhood, a former naval shipyard that was—until recently—one of the most polluted sites in the country. After 20 years of remediation work, the enclave at the southern tip of San Francisco is now slated to receive upward of 10,000 new housing units as well as a slew of recreational and commercial programs.
The 60-unit apartment complex—developed by AMCAL Multi-Housing and Young Community Developers—is located near the center of the new environ, at the corner of Friedell Street and La Salle Avenue. The complex is organized as two interlocking L-shaped wings bridged by a two-level courtyard. The building features units ranging from one- to three-bedrooms supplemented by ground-level assembly and amenity spaces.
The five-story complex is punctuated along Friedell Street by a perforated Cor-ten steel panel–clad circulation tower that connects to a monumental stairway running through the principal courtyard. That stairway jogs across the elevated portion of the courtyard and eventually empties out onto a generous seating area with custom benches and native plantings. That elevated portion conceals play areas, building programming, and parking below, while stretching deep into the site where it is overlooked from multiple vantages by single-loaded corridors leading to unit entrances. The courtyards are articulated by generous planters framed by Cor-ten steel panels that are interrupted by jagged, stepped benches and wood platforms. Andrew Dunbar, principal at Interstice Architects said, “A fresh-air entry court is located at the lower level; above the parking, we were able to create a park-like courtyard that creates an intimate interconnecting ‘front yard’ for all the inhabitants.” The seating areas contain an unusual element: Raw 10-foot-long logs are embedded directly into the seating and stage areas. “We liked the surrealist effect of the logs as floating elements in the sea of wooden water—they speak to driftwood and offer imaginative play opportunities that recall the logging industry that once used the bay,” Dunbar explained.
The remainder of the complex is organized as a series of simple apartment blocks with several alternating sections of massing projecting beyond the main bulk of the complex. These overhanging areas create coverings for doorway stoops in certain areas and provide simple shade over windows in others. Along the stoops, the scale of the building breaks down to include more raised Cor-ten steel panel planters, modestly planted green areas, and broad stair landings designed for children to play on.
In most areas, the units are studded with flush-mounted floor-to-ceiling casement windows articulated to look double-hung. Window assemblies containing large picture windows are wrapped by planar shading devices that demarcate certain aspects of the program—namely the living areas. As is customary in much of DBA’s recent work, these shared ground-floor areas are detailed with smooth, cast-in-place concrete. The articulated portions of the building containing housing programs are variously clad in smooth, painted stucco, or horizontal siding.
Artists such as Pablo Picasso have frequently used Cor-ten steel, which has a distinct reddish brown color, for outdoor sculptures. Recent prominent architectural uses include the Barclays Center in Brooklyn and Bjarke Ingels' Warehouse421 in Abu Dhabi. U.S. Steel, who owns the patent on Cor-ten, showcased the product during the construction of their U.S. Steel Tower in Pittsburgh.
Most of Judd's works with Cor-ten steel were done for specific outdoor locations and commissioned by clients. This book collects photographs taken during an exhibition at David Zwirner's New York gallery. It is currently available on the publisher’s web site.

Custom sliding wood shades maximize privacy and views in Adirondack Mountains retreat.Architect-led design build firm GLUCK+ designed the Lakeside Retreat in the Adirondack Mountains on an historic blueprint: the Great Camps, sprawling summer compounds built by vacationing families during the second half of the nineteenth century. "The clients wanted to hold events there, and to make a place where their kids—who were in college at the time—would want to spend time," said project manager Kathy Chang. "They wanted to create different ways of occupying the space." GLUCK+ carved the hilly wooded site into a series of semi-subterranean buildings, of which the two principal structures are the family house and the recreation building. These buildings are, in turn, distinguished by massive lake-facing glass facades, camouflaged by wooden screens designed to maximize both privacy and views. The project, explained Chang, "was really about sculpting in and out of the landscape, manipulating the ground plane." By using the existing site as a primary element of construction, the GLUCK+ team was able to accomplish two things. First, "it gave us a new level area for the clients to hang out outside," said Chang. "It provided a new way to occupy the site, because before there was no flat ground." Second, they were able to manipulate the program so that the mechanical spaces were tucked into the underground portions of the houses, making way for a transparent facade along the lakeside. "The fact that so much of the program is buried allowed us to build the glass facade, despite the energy requirements," said Chang. The custom curtain wall is in fact quite simple, said Chang. "What made it custom was sizes and the ability to integrate the screen support: we have various slope conditions, and at the highest point the pieces are really very heavy." GLUCK+ installed Siegenia lift and slide hardware to insure easy operation of even the largest sliding glass doors. "The client was really intrigued with the idea of open sleeping porches," said Chang. "They wanted to be able to open up the house and have the breeze come through." The screen system was partly a response to concerns expressed by the local environmental commission. "The commission was very nervous about having a tall glass building facing the lake," recalled Chang. "We set the buildings back from the lake, in the trees. In addition, part of the idea of the screen was to break down reflections from the glass so that it wouldn't be so apparent from the lake." The wood shades are arranged in two layers, both attached at the top to the underside of the roof slab. Stainless steel outriggers placed in the window system between the first and second stories provide an additional point of attachment for the screens above and below. To reduce the gravity load, the outriggers are supported by cables attached to the roof slab. Each screen comprises thermally modified poplar slats from Cambia Wood affixed to a Cor-ten frame with horizontal steel elements for additional strength. "We calculated that there's almost four miles of wood, so we really spent a lot of time looking at different options, at different ways to price it and build it," said Chang. "We looked at doing this in mahogany or other woods typical for outside use, but both the weight and expense were prohibitive." GLUCK+ performed analyses to determine which rooms would require more or less privacy, or open spaces at sitting or standing levels for views. Many of the screens are designed to slide from side to side. In addition, some individual slats can be rotated to enhance privacy. On the top level of the buildings, the (fixed) inner layer of screening doubles as a balcony guardrail. GLUCK+ used the same poplar on the buildings' other exterior walls, some of which are occupied underneath, others serving as filler. "We used the same wood in a more solid condition to try to tie those walls in with the screen, and with the solid earth," said Chang. "It's really hard to tell where the building stops and the landscape begins." Because one building was ahead of the other during construction, Chang and her colleagues had the opportunity to compare the uncovered curtain wall with its shaded neighbor. "The unscreened building just looked naked and cold," she said. "It didn't have this life to it." The clients, reluctant at first to embrace the screens, agreed. "In the beginning of the process, the clients were a little worried about losing the view," recalled Chang. "We needed iterations of the mockups to convince them: no, it's actually adding to it. It ended up being one of their favorite parts of the whole project."
A folly in a Rotterdam suburb draws on residents' complex relationship with the city.The residents of Carnisselande, a garden suburb in Barendrecht, the Netherlands, have a curious relationship with Rotterdam. Many of them work in the city, or are otherwise mentally and emotionally connected to it, yet they go home at night to a place that is physically and visually separate. When NEXT architects was tapped to build a folly on a hill in the new town, they seized on this apparent contradiction. “This suburb is completely hidden behind sound barriers, highways, totally disconnected from Rotterdam,” said NEXT director Marijn Schenk. “We discovered when you’re on top of the hill and jump, you can see Rotterdam. We said, ‘Can we make the jump into an art piece?’” NEXT designed The Elastic Perspective, a staircase based on the Möbius strip. “The idea of the impossible stair [is] you’re not able to continue your trip. At first it seems to be a continuous route, but once you’re up there, the path is flipping over,” explained Schenk. “That’s a reference to the feeling of the people living there.” To catch a glimpse of Rotterdam, users must turn their backs on Carnisselande. Yet while the view is in one sense the destination, the staircase ends where it started, in the reality of the garden suburb. NEXT began by experimenting with strips of paper and thin sheets of steel to form the staircase’s basic shape. The architects then turned to AutoCad, where they finalized the design before 3D printing a 1:200 scale model. NEXT worked with engineers at ABT throughout the process. They relied heavily on 3D design software, Schenk said, “because all the steel was sort of double-curved.” Mannen van Staal fabricated the staircase from seven steel panels custom-cut with a CNC machine, said project architect Joost Lemmens. They bent the plates, largely by hand, and assembled the entire structure in their factory, temporarily welding the pieces together. They then disassembled the structure for transport to the site, where the components were re-welded by hand and using a vacuum-cleaner-sized robot. Cor-ten was a practical choice on the one hand because the rust obscures the stitches used to reconnect the seven panels. In addition, said Schenk, “It’s weatherproof, and sustainable in the sense that we’re not using a toxic coating.” The choice of Cor-ten also holds aesthetic and cultural meaning. The orange of the staircase contrasts with the green of the hill. Plus, “it’s a material quite often used in artworks, so of course it refers to the work of Richard Serra [and others],” said Schenk. “I think in short what it’s about is the idea of making a jump, make people be able to make a jump to see the skyline of the city,” he concluded. “We’re using the Möbius strip to express the ambiguity of the people living there: feeling connected to Rotterdam but being somewhere else.”
