ZGF designed Indigo @ Twelve|West aims for LEED Platinum
Rising 23 storeys above Portland, Oregon’s evolving West End neighborhood, Twelve|West is a mixed-use building designed to achieve two LEED Platinum Certifications and serve as a laboratory for cutting-edge, sustainable design strategies. It features seventeen floors of apartments, street level retail space, four floors of office space and five levels of below-grade parking. The building has an eco-roof, rooftop garden and terrace space, theatre and complete fitness studio. Four wind turbines sit prominently atop the building representing the first U.S. installation of a wind turbine array on an urban, high-rise.
The design team sought to enrich the Portland skyline, connect the building’s inhabitants to the urban landscape, integrate advanced sustainable building systems and design homes for lease that maximise space, light, views and include luxurious and energy saving amenities.
These goals are embodied by a transparent, carefully articulated curtain wall that gives the building a thin and planar structural aesthetic. To add variation, the building’s southern façade is slightly angled. Subtle textural modifications including operable windows, balconies, quilted and recessed stainless steel of varying color, and fritted reflective semi-opaque panels create a lively enclosure with a sense of movement.
The 273 Indigo @ Twelve|West apartments, which begin on the 6th floor, offer a mix of studios, one-, two-, and three-bedroom units ranging in size from 541–2125 sq ft and three floors of penthouse homes. The interior material palette optimises the light coming into the home and varies with each layout option. Concrete is left exposed at ceilings and walls where possible, for a loft-like feel.
Sustainable materials are used throughout the apartments, including bamboo veneer casework in kitchens and bathrooms, carpet in bedrooms with 25% recycled content, granite counter tops in kitchen and baths, PVC-free window coverings, zero-VOC paint, low-flow plumbing fixtures and Energy Star appliances.
