Jill Fortuna captured an in-studio micro-mockup today, created by Patrick Nelligan using brick samples that were vetted and tonally mixed for a recent Texas project. Ben Nardi and Jordan Bell assisted in the layout and hard-soled-shoe / cuffed-pant testing of the surface.

Swipe to see the newly opened up views and restored public entry into the magnificent courtyards and arches!

Since 2019 GGN has been a creative and technical partner with PacSci and its diverse community, to study ways to preserve and celebrate this landmarked treasure of a space designed by Minoru Yamasaki, while welcoming more people, curiosity, and nature into the space.

At the South Entry, we are delighted to see the positive response from visitors who have come to watch the former gates and surrounding barriers (all added into the 1962 entrance plaza in the 1990s) come down!

construction performed the surgical work to remove the interconnected, dense layers of 1990s additions from this courtyard entry with minimum disturbance and maximal questions from curious passerby.

This was originally the main public entry to the US Science Pavilion (now PacSci).

At this (now restored and reopened) courtyard entry, guests crossed into the courtyard by ascending or descending stairs that lead to floating platforms that bring a person’s body through the air, light, and the ethereally inspiring Arches.

Mr. Yamasaki intended this entry as a communal ritual of civic crossing — leaving the regular ground of our days behind us — clearing distractions and opening our minds together, for taking in the new ideas and exhibits within the Pavilion.

Today, visitors to and can once again stroll freely into and through the magical, mind-clearing Arches to find a place of both inspiration and respite, community and contemplation. We suggest exploring the many beautiful and innovative details in this significantly intact work by Minoru Yamasaki, including original planters and benches!

Go check it out to see an example of the power of “doing less” in design and construction to reveal more for all of us to enjoy. Thank you to for welcoming curiosity and for being brave with experimenting in their own space.

We are pleased to share that the first phase of India Basin Waterfront Park@received an Honor Award at the recent 2026 Design Awards Ceremony. This honor is shared with our client and community partners and our architectural team members , who brought the unusually sited and locally programmed, small park buildings in the design plan into full and vibrant life that already activates Phase 1 of the park.

For over a decade, we’ve been honored to be entrusted with the overall planning and design of this special project, from the neighborhood-driven planning and programming, to community-inspired site design and detailing, to collaborating with a talented team of consultants and contractors on making concepts into reality, since winning a design competition in 2016.

Project client and design team:
Client: Trust for Public Land
San Francisco Recreation & Parks
Lead Design, Prime Consultant, Landscape Architect: GGN
Architect: Jensen Architects
Ecological Restoration / Planting Design: Rana Creek
Structural Engineering: JBSE Inc. (dba Jon Brody Structural Engineers)
Lighting: Niteo California
MEP & IT: Interface Engineering
ADA Consultant: Marx Okubo
Historic Consultant: Page & Turnbull

Situated along 1.5 miles of San Francisco Bay shoreline in the Bayview-Hunters Point neighborhood, this project transforms a historically industrial site into a resilient waterfront park that is connected to a long-isolated but vibrant neighborhood.

Restored tidal wetlands, native plantings, and marsh create a thriving ecosystem and climate resilience, while new walkways connect long-isolated neighborhoods to the water — reclaiming a polluted shoreline as an inclusive landscape bridging nature and community.

As the Tellima and Camas are in full bloom today at this Seattle garden of locally native plants, we are honored to share the inclusion of this special project in Phaidon’s The Contemporary Garden, from co-editors Victoria Clarke, Sorrel Everton, and Rosie Pickles.

It is heartening to our collaborative and mission-driven clients, as well as to our Meadowshop team (who focuses on continuing the approach using insights from this garden and our preceding years of test beds), to see this garden included in a global survey of gardens that look to the future.

Plants in this garden were mostly sourced from our friends at . Horticulture was shaped and established by

This week GGN’s Chihiro Shinohara and .malda joined students from for the 2026 All-Department Charrette:Resilient Campus! in Urbana Champaign. During the three-day workshop, over 75 students explored the pasts and potential futures of their campus. Students divided into three groups led by , and . Student leaders worked with these professionals to shape the process and themes for their teams. The workshop culminated in presentations that connected collective ideas with individual student explorations.

The GGN team encouraged students to explore deeper layers relationships of the land to the university’s land-grant legacy and the campus as they know it today. This led to the development of multiple experimental “plots” that build on initiatives across the campus that are connecting ecologically rich moments with communities of making, learning, and ongoing-care for the land. The final presentation emphasized the value of storytelling as a part of landscape architecture along with specific “plot” proposals.
