Bringing a precise plan to life

1625 Plymouth brings the North Bayshore Precise Plan’s vision to life by supporting a dynamic, mixed-use neighborhood where technology, sustainable urbanism, and natural habitats converge. Collaborating closely with the city and the developer, we successfully navigated a complex entitlement and rezoning process, securing increased density by exceeding city standards for public amenities and sustainability features.

Enriching the public realm

The development was envisioned as an sculptural centerpiece within a public garden, prioritizing the community’s enjoyment of the surrounding landscape. A large public plaza, located at the terminus of a heavily-trafficked street, creates open space for community use. An amenities pavilion, fronting another busy street, is situated beneath an office bar, forming an active and shaded gathering area.

Landscaped pathways link the streetscape to the future bike greenway outlined in the North Bayshore Precise Plan. This greenway bisects the pedestrian-friendly block, creating separation between the office building and the parking structure while promoting a more walkable, engaging environment.

A glass box, green

The building’s six floors rise above the amenities pavilion, featuring column-free interiors that foster flexibility and collaboration. A striking monolithic scissor stair creates a dynamic visual connection between the tower and pavilion, while adding architectural interest at street level.

The all-glass aesthetic of 1625 Plymouth, while key to its market appeal, posed challenges in meeting sustainability goals. Strategic overhangs, solar fins, and high-performance crystal gray glass were incorporated to mitigate heat gain. These strategies, along with solar panels and high-efficiency heating and cooling systems, helped 1625 Plymouth achieve LEED Platinum certification.

Infrastructure as art

The adjacent parking structure, equipped with EV charging stations, is clad in a refined aluminum mesh that plays with light and shadow. A circular elevator tower, encased in frosted channel glass, punctuates the structure. Praised by city officials, its unique form and materiality were designated as the development’s public art feature.

Reimagining Silicon Valley

After Google fully leased the building, they engaged WRNS Studio to design the interior fit-out and strengthen its connection to the broader Google campus. Alongside WRNS Studio’s projects for Microsoft and Intuit, 1625 Plymouth envisions a more walkable, sustainable, and socially connected North Bayshore.

A vision for community

Paying homage to San Mateo’s distinct sense of place and strong community was important to Prometheus Real Estate Group, a family-owned company dedicated to creating homes and neighborhoods that feel authentic and foster a sense of belonging. The company—which recently opened its new headquarters onsite—was founded upon the vision to transform apartment living by attending to every inch of detail, from site selection to interiors. This culture of excellence has enabled Prometheus to give back their time and, on average, over thirty percent of their cash flow (through their foundation, the Helen Diller Foundation) to support positive change, locally and beyond.

Northern California roots

Prometheus wanted their new headquarters to echo the richly layered, community-rich experience of their apartment offerings, while celebrating the company’s Northern California roots. In response, no detail was spared, resembling the approach of a custom residential project. Bespoke and familial, Prometheus’ new workplace feels like a welcoming home, embracing  the mild climate and the natural beauty of Northern California. Spanning 28,750 square feet across Brickline’s third and fourth floors, it features ample terraces and a rooftop deck with views of San Mateo Station and the Santa Cruz Mountains, blending indoor and outdoor spaces.

Movement and connection

Set back from the bustling street, an intimate terracotta-clad portal leads to a formal lobby where an elevator then takes people to a foyer, offering direct access to workspaces or communal areas. Kitchens, conference rooms, and other meeting areas encircle a central stair, encouraging people to socialize and move about the building. Extending from the third floor to the roof, the stair, capped with a glass and louvered roof, draws natural light deep into the space, while patterned wool wall coverings add texture along this sunlit path.

A modern, multifunctional heart of the workplace

A light, airy Living Room on the fourth floor serves as the heart of the Prometheus community. Inspired by California’s iconic residential modernism, the space—like all common areas—embraces openness, multifunctionality, and indoor/outdoor flows. Textiles, wood accents, and metals evoke a coastal California feel. A large kitchen with a double island anchors the room, fostering gatherings for meals, events, and meetings. Movable furniture, a retractable projector, operable walls, and automatic shading allow the space to flex for various uses. Beadboard cabinets, quartz countertops, and handmade Italian ceramic fixtures add an elevated, domestic charm.

Tailored spaces that feel like home

Hand-crafted details, bespoke furniture, indoor plantings, art, and discreet technology create a refined, relaxed atmosphere. The Founders’ Den features a marble top table with a red leather base, a custom rug, and grass cloth wallpaper that quietly textures the naturally lit space. Built-in cabinetry and concealed screens maintain a tranquil, home-like feel. Walnut millwork and a shiplap ceiling distinguish the Study, an informal social space. A large Conference Room is designed for easy transformation while maintaining acoustical isolation. Custom white oak storefront doors subdivide or open the space, while personal touches, like copper pulls and leather and felt panels, soften the space.

Residential comfort meets functionality

Individual workspaces for Prometheus’ close-knit team are organized into small neighborhoods to promote focused work. A red cedar slatted ceiling and wool felt panels mitigate noise while defining the workspace neighborhoods. High-quality commercial-grade carpeting in a refined herringbone pattern, combined with light fixtures featuring acoustic felt with a heathered finish and white stitching, evoke the warmth of a living room or hospitality setting. Custom millwork enhances private office glass walls, while thoughtful features like a walnut banquette provide transitions between collaborative areas and focus zones.

A reimagined campus

Nestled low into the landscape, the reimagined two-story campus now offers a workplace that synthesizes the well-being of both people and the environment. Employees will just as likely delight in their individual workspaces—light-filled spaces crafted of unadorned, honest materials like wood and concrete that look onto vegetated courtyards—as they will the expansive living roof, featuring  eateries, fitness amenities, and trails leading out to the nearby creek. regenerating local habitat and site ecology.

A spirit of reuse over replacement

In line with Microsoft’s commitment to the circular economy, we opted to reuse two buildings, reducing material waste and minimizing operational disruption. The existing buildings provide 36% of the new campus footprint, significantly minimizing embodied carbon.

“Many buildings start with a design concept and work backwards to mitigate harm to the local ecosystem and natural resources. Our design started with a different goal in mind—could we design a building that was actually beneficial and restorative to the local ecosystem? We think we’ve achieved just that.”

Darren Lombardi
Former Design and Construction Manager, Microsoft

Inside-out approach 

The inside-out design strategy arose from a deep investigation into Microsoft’s culture and operations. While leadership sought a community-driven workplace, interviews revealed that engineers favored small, quiet spaces for solo or paired work. The solution was a series of human-scaled neighborhoods that balanced privacy and collaboration, fostering a sense of ownership among distinct groups.

We explored nine space types ranging from collaborative to private, ultimately narrowing them to three that struck the right balance. The front-runners offered a flexible platform for authentic, personalized work experiences, while creating an environment where employees could move easily between focus and collaboration. The space types guided our site analyses and allowed us to identify a preferred option that delivers a holistic, inside-out campus experience.

Indoor/outdoor integration

Design leverages Mountain View’s Mediterranean climate, creating shaded, comfortable outdoor conference rooms with seamless tech integration. These spaces enable Microsoft’s creatives to work and socialize outdoors year-round. This approach allowed us to capture outdoor usable space without tapping into the FAR.

A walkable campus with diverse amenities

Inspired by the dense, mixed-use neighborhoods of great walkable cities, the campus generates a human-scaled experience of discovery and prospect in which people are invited to wander through alleyways, up staircases, around outdoor decks, and along the green roof’s many pathways. Amenities include dispersed and differently scaled gathering areas, recreation zones, food and beverage stops, a café overlooking Stevens Creek in which the whole campus can gather, and a public tech center that houses galleries and a theater.

Cross-laminated timber: performance and wellness

As one of North America’s largest mass timber projects at the time of construction, the campus embodies Microsoft’s goals for low-carbon construction, employee well-being, and supporting local industry. Extensive use of CLT—including structural components that double as interior finishes—offers a warm aesthetic while minimizing materials. This approach resulted in an estimated 35% reduction in embodied carbon.

Energy efficiency

A high-performing envelope improves comfort and reduces energy demand by 55%. Beyond main cooking functions, the campus is fully electric, featuring four thermal energy storage tanks that reduce central plant size and shift grid demand to non-peak periods. Photovoltaic panels further offset the heavy electrical loads of this technology-driven workplace, supporting a sustainable and energy-efficient design.

Water conservation and management

Despite a 40% increase in employee capacity and tripling the landscape, design reduced water consumption by 57%. Rainwater is captured in two 60,000-gallon pretreatment tanks, filtered, and then stored in blending tanks. Building wastewater is collected, then treated through a series of packed-bed filters, vertical wetlands, membrane filters, and ozone and UV disinfection before it is stored in the blending tanks. 

The campus features an on-site water treatment facility designed to achieve net-positive water usage, with plans in place to meet 100% of potable water needs. This pioneering approach required collaboration with city officials, fostering a spirit of innovation and setting a precedent for future water management practices in Mountain View. Visible filter systems, wetlands, and tanks highlight the client’s commitment to ecology and community.

Water management and local ecology

The project’s water filtration and conveyance system mimics Stevens Creek’s natural watershed, enhancing local ecology. Stormwater from the campus’s sidewalks, green roof, and landscape is channeled through wet meadow biotreatment and retention basins, infiltrating the banks of Stevens Creek. This process revitalizes the soil, restores the natural habitat, and ultimately directs clean water into the San Francisco Bay.

Regenerative site ecology and habitat restoration

A regenerative approach, guided by the area’s pre-industrial condition, led to the reintroduction of native ecology and the restoration of nearby Stevens Creek. Historically, riparian and oak habitats were prevalent in this area; in addition to planting nearly 600 trees, the habitat enhancement along Stevens Creek benefits over 50 species, including migratory songbirds, terrestrial mammals, and butterflies. Improvements to a well-loved public trail invite the wider community to explore and enjoy the revitalized creek and its natural surroundings.
