This project is going to be a true city center - our downtown retail anchor - befitting a world class city.”
- Mayor Adrian M. Fenty

CityCenterDC is a 10-acre site in the heart of downtown Washington DC, developed by Hines/Archstone with architecture led by Foster + Partners. CityCenterDC converts former superblocks into a mixed-use urban center with a fine-grained network of streets and alleys, plazas, a park, and multiple landscaped terraces.

Bill & Melinda Gates Foundation Campus

The Bill & Melinda Gates Foundation campus is designed as a locally grounded environment for global work and dialogue. In concert with the campus architecture by NBBJ, GGN designed a campus landscape for outdoor work and collaborative problem-solving. 

Phase One of the campus was completed and certified LEED NC 2.2 Platinum in 2011.


National Museum of African
American History & Culture

The landscape design for the National Museum of African American History and Culture situates the NMAAHC within the context of the Washington Monument Grounds as an object in a field, drawing the open, pastoral nature of the Washington Monument grounds through the Museum site.


Robert and Arlene Kogod Courtyard

The Robert and Arlene Kogod Courtyard at the Smithsonian American Art Museum and National Portrait Gallery is located in a National Historic Landmark Building in Washington, DC. This award-winning project was a collaboration with Foster + Partners.

Civic Park at Hemisfair

The Gustafson Guthrie Nichol design for the civic park at Hemisfair creates a place that fits San Antonio’s life, character, and vision. "San Antonio's unique culture is rooted in a rich heritage of outdoor gathering,” said Founding Principal Kathryn Gustafson. “The civic park presents a new capacity for the city's greatest celebrations while also establishing the foundation for new urban growth and connections."


Chromer Building Parklet & Streatery

The Chromer Parklet converted five parking spaces into a new public space that serves the neighborhood with the highest pedestrian counts in downtown Seattle. GGN designed the Parklet as a simple, modular system that uses replicable, durable elements to create the series of flexible, level spaces on a sloped Seattle street. 


University of Washington Lower Rainier Vista

GGN's new design of Lower Rainier Vista extends, clarifies, and finally completes the Vista, reconnecting the isolated Montlake Triangle to the whole of the UW campus.


Yakima Central Plaza

“As someone who grew up in Yakima, I want to do an absolutely stellar piece in my home town,” said Kathryn Gustafson. “For me, this project is about the place where I was born and raised before I went out into an international realm. What can that international realm bring back to the vernacular of the local? That’s my challenge and what I find fascinating about this project.”

Norton Museum of Art Expansion

Internationally recognized for the strength of its permanent collection, the Norton Museum of Art in West Palm Beach Florida is undergoing an expansion. The master plan by Gustafson Guthrie Nichol and Foster + Partners restores the original symmetry and circulation by relocating the entrance.


Unified Ground:
Union Square National Mall

"Our design for a durable and flexible plaza will bring life and activity to the site and will take the pressure from the mall's lawn panels, making it a more sustainable landscape."
Rodrigo Abela, Principal

This winning design for the Union Square Competition, situated at the base of the Capitol in Washington DC, engages visitors with an impressive monumental scale, while also providing comfortable places for a range of experiences and voices. 


Pike-Pine Renaissance Streetscape Design
Concept and Action Strategies

The Downtown Seattle Association engaged GGN to create an implementable, detailed plan of phased, opportunistic streetscape improvements to refresh the city's downtown core. GGN responded by proposing a consistent return to the city's simple, historic sidewalk standards -- tweaked to strengthen the contrast between avenues and streets -- along with a bold prioritization of pedestrians at intersections.

University of Washington
West Campus Residences

“. . . the urban design of this challenging project is excellent. The sitting areas and other public space details are meaningful and the public connections at the large and small scale really work."
- 2013 AIA Washington Council Civic Design Jury

Encompassing four city blocks, the UW West Campus Residences create a balance of public and private spaces. 


North End Parks

The "Big Dig" burial of the I-93 Freeway beneath Boston created a swath of reclaimed land through downtown. The North End Parks, a 3-acre series of parcels on the tunnel lid, created a welcoming social space at the threshold to the North End neighborhood.

The Parks, GGN's collaboration with CSS Boston, opened views and restored street connections that had been severed for decades. 


Venice Biennale -
Towards Paradise

Towards Paradise was the first significant installation of landscape as part of the Venice Architecture Biennale. The installation was conceived as a contemporary allegory in the broadest sense - taking the visitor on a journey through earthly dilemmas, evoking what has been lost and what can be gained between man and the landscape.


Maggie Bench
for Landscape Forms

Originally designed by GGN for Chicago’s Millennium Park, the Maggie Bench expresses the form and gesture of the human body with a light stance and a minimum use of materials. Click here for more information about Maggie.


Vancouver Community Connector

GGN's winning proposal for the Vancouver Community Connector reconnects a severed downtown core that was divided by the I-5 freeway. The design laces multiple, street-scale connections across a landbridge structure that is designed -- in collaboration with Allied Works and Arup -- like a honeycomb, to treat and hold stormwater through filters of native plants and deep soils.


University of Washington
School of Medicine Phase 2

Situated in South Lake Union, Seattle, the design created a distinct identity for the UW School of Medicine, while responding to the programming needs of a biotech-research facility.. 


Charlie Table
for Landscape Forms

Originally designed by GGN for Chicago’s Millennium Park, the Charlie Table re-imagines the traditional picnic table as a fluid and ergonomic piece of furniture. Charlie's open ends provide integrated wheelchair access. Click here for more information about Charlie.
