The design of 1771 N Street takes a 1960s legacy building and updates it with a new façade, rejuvenated outdoor spaces and interior improvements. The LEED Gold Core and Shell renovation reduced building energy and water use both by over 35% and provides on-site stormwater management. 

The hallmark of the renovation is a new, six-story glass façade that sweeps across the building’s southwest side. The unitized curtain wall system follows the building’s concave form. Fritted glass fins along the façade provide a building with a sense of verticality, shading and lightness.

A spacious entry plaza focuses on the creation of human-scale spaces, akin to “rooms in the garden,” shaded by trees. The connection to nature continues eight stories above the plaza where a new rooftop garden provides breathtaking views of the city skyline. The intensity of lush plantings and bioretention set on top of existing on-structure car parking and office space.

A re-configured floor plate, envelope upgrades and replacements provide all building occupants with exterior views and daylight. Use of a highly efficient and space-saving VRF HVAC system allowed the design team to convert a mechanical penthouse into a rich, new amenity space and a rooftop terrace with dramatic views of the city.
