Gold Prize

Articulate Site, Colombia
By Mario Fernando Camargo Gómez and Luis Orlando Tombé Hurtado of Colectivo 720

From the architects:

This project for a public park centers on creating spaces around and above a series of water reservoirs. Architectural form takes inspiration from the site’s history, surrounding topography, and structure of the existing tanks and pools, resulting in an intervention with minimal environmental impact. Special attention is given to water management, using recycling technologies involving rainwater and grey water harvesting through simple systems for irrigation of the park.

Silver Prize

Post-War Collective, Sri Lanka
By Milinda Pathiraja and Ganga Ratnayake of Robust Architecture Workshop

From the architects:

With the aim of reintegrating former soldiers into post-civil war society, young men from underprivileged backgrounds are trained in building techniques through their involvement in the construction of public buildings – such as this Community Library. The slender building sits lightly in the landscape and wraps around an inner courtyard, taking full advantage of cross ventilation and daylighting. Rammed-earth walls and recycled materials reduce the building’s ecological footprint.

Bronze Prize

The Dryline, New York City 
By BIG, One Architecture, and Starr Whitehouse Landscape Architects and Planners

From the architects:

The Dryline (or BIG U) project addresses the vulnerability of New York City to coastal flooding and proposes a protective ribbon in Southern Manhattan. The master plan uses a raised berm to create a sequence of public spaces along the raised bank at the water’s edge. The infrastructural barrier incorporates a range of neighborhood functions and as a result offers multiple design opportunities, fostering local commercial, recreational, and cultural activities.
