Project Highlights

Eureka Valley Home — Studio Mala + Gast Architects

At a serene garden retreat in Eureka Valley, on the eye-opening AIASF Home Tour, Studio Mala demonstrates how outdoor comfort begins with structure. Here, custom S4S site furniture defines the garden’s geometry, forming low linear seating with integrated planters that hold trees and garden florals. The continuous horizontal rhythm of the alternating-width S4S boards at the fencing echoes the precision of the site furniture, enhancing the visual harmony of the exterior.

Above the seating area, a discreet deck designed by Gast Architects balances clarity and outdoor connection with warmth. Their exterior wood handrail, slim and modern, adds a tactile touchpoint without interrupting the view, exemplifying how good design can remain subtle while also skillfully enhancing each moment in a space.

Hayes Valley Residence — Manon Paquet

Across town in Hayes Valley, a residence originally crafted by Dan Solomon Architecture has been sensitively reimagined by architect Manon Paquet. The home’s private deck, fencing, with a splashy seating area illustrate how custom S4S boards support the art of modern outdoor living.

Horizontal wood fencing, topped with a fence cap, establishes privacy while maintaining airiness and continuing the linear movement of the wood decking. Heated built-in furniture extends the home’s usability year-round, a thoughtful enhancement for enjoying San Francisco’s microclimates. Each element, from wood decking areas to the perimeter edge details, reflects how architectural woodwork outdoors can carry the same level of precision and impact as fine millwork inside.

This site reveals the flexibility of S4S garden design as both finish and frame. By shaping a linear language through orientation, proportion, and placement, Paquet achieves a space that feels crafted rather than left over, one that encourages pause, gathering, and reflection, an investment that surely pays off in spades for years to come.

Studio in partnership with OMA, showing us how custom S4S boards for exteriors can refine an outdoor environment with thoughtful design moments, designed by GLS Landscape Architecture.

Haight-Ashbury Affordable Housing — Y.A. Studio, OMA + GLS Landscape Architecture

At the edge of the Haight-Ashbury neighborhood, the Haight Street Affordable Housing project, designed by Y.A. Studio in collaboration with OMA and GLS Landscape Architecture, redefines what shared outdoor spaces can be.

Within this new urban landmark, S4S site furniture plays a central role in shaping community. The custom looping bench features a slanted wood back and curved lines circling an evergreen tree, with small built in micro tables, ideal for food, beverage or a favorite book. The inward shape of the curved plan lends itself to conversing with others or pleasant solitude. This bench element is both sculptural and interactive. The form softens the building’s contemporary massing, bringing warmth and texture to the courtyard while offering residents a sense of place through well-crafted details. It offers a sense of arrival, distinction and place to meet up.

Featured on ArchDaily and the 730 Stanyan Project site, the development demonstrates that affordable housing can also be a showcase of design excellence. Through thoughtful collaboration between architects and landscape designers, the project shows us that custom S4S profiles, when planned out thoughtfully, can unify architecture, public space, and human experience in meaningful ways.

Design Details

Several of these gardens on the tour highlight how S4S site furniture and fencing support modern landscape architecture through versatility and precision. Straight-edge boards allow designers to scale elements exactly to proportion, creating surfaces that flow seamlessly from wall to bench, from deck to fence. As noted in Sunset Magazine’s guide to designing a sustainable backyard, lasting outdoor spaces begin with thoughtful material selection and structure, principles echoed in these San Francisco landscapes. When fabricated in durable wood species suited to the Bay Area’s coastal climate, S4S boards can perform structurally while maintaining their refined visual line over time.

This design language bridges two worlds: the tactile craftsmanship of custom wood trim and the modular adaptability of outdoor construction. In each project, the result feels effortless, yet it’s the product of close coordination between fabricators, architects, and landscape architects, and builders. Each installation on this tour showcases how custom-specified and fabricated wood elements can meet performance goals while enriching daily experience through warmth and tactile quality.

Historical Context

This approach builds on a century of California landscape design, where natural wood has long served as a bridge between built form and nature. The use of wood in landscape architecture has deep roots in American design history. Pioneers such as Frederick Law Olmsted, whose Bay Area work included the plan for the original Stanford University campus with Shepley, Rutan & Coolidge, integrated timber structures and wood furnishings that harmonized built form with the natural landscape. Later, Lawrence Halprin, working extensively in California, advanced this dialogue through Bay Area collaborations such as adaptive-reuse landmark Ghirardelli Square with William Wurster, Levi’s Plaza with Skidmore, Owings & Merrill, and Sea Ranch with Joseph Esherick and the collective MLTW (Charles Moore, Donlyn Lyndon, William Turnbull Jr., and Richard Whitaker). At Sea Ranch, Halprin’s coastal wood boardwalks and terraces complemented Esherick’s and MLTW’s redwood-clad buildings, setting a precedent for environmentally responsive design. Together, they helped expand and define the Bay Tradition, where craftsmanship, climate responsiveness, and natural materials, including redwood, created a uniquely Californian architectural language. Their work established natural wood as both structure and experience, a medium connecting architecture to nature through scale, rhythm, and touch, an ethos that continues in today’s S4S landscape applications and resonates with architects and occupants alike.

Material Focus: S4S in the Landscape

While S4S boards are a familiar presence in interior trim and millwork, their exterior applications open a broader field of design potential. Used for site furniture, decking, caps, and fencing components, they give outdoor rooms the same finish quality found indoors. The flexibility of S4S allows architects to tailor dimensions, joinery, and finishes for function, whether seating, screening, or planters.

As the AIASF Home Tour demonstrates, the move toward crafted outdoor living isn’t a passing trend but an expansion of architectural detailing into the garden. The precision once reserved for baseboards and casings now elevates benches, railings, and garden walls. As highlighted by Sunset, gardens also support wellbeing through layered sensory design, something precise wood detail enhances through tactile connection and rhythm.

FAQ About S4S Site Furniture

What is S4S site furniture?
S4S stands for “surfaced four sides,” referring to wood boards that are planed smooth on all faces in any species. When fabricated with a custom profile at custom lengths, builders can make site furniture such as benches, screens, fencing or built-in planters, architecturally consistent outdoor furnishings with precision. Architects, Landscape Architects, and Builders turn to Lowpensky Moulding to provide custom S4S fabrication on both residential and commercial projects.

What wood species are suitable for outdoor S4S site furniture?
Durable, sustainably sourced species like cedar, redwood, or IPE, are popular with Architects and builders for Bay Area climates, offering longevity without sacrificing the fine texture and material palettes designers expect from architectural-grade wood. Lowpensky Moulding provides architectural-grade fabrication of wood for fencing, decking, handrails, including FSC®-certified species when requested, milled per customer specifications for each project.

How does custom fabrication enhance outdoor S4S garden elements?
Custom fabrication reduces waste and therefore costs by providing custom lengths in the specified species, ensuring dimensional accuracy, and precise profiles, key to achieving the seamless visual flow seen in high-end landscape projects, and for efficient installations. Lowpensky Moulding has fabricated made-to-order S4S profiles for Northern California projects since 1947.
