Austin Sandy Architects Builds an Open Timber Pavilion for Community Life on a Petaluma Organic Farm

Farm buildings tend to fall into two camps: the purely utilitarian shed, or the event barn dressed up for weddings. The Live Oak Farm Pavilion, designed by Austin Sandy Architects (Joseph Sandy and Pete Austin), sits deliberately between them. Completed in 2024 on a certified organic farm in Petaluma, California, the 1,200 sq ft structure is a shared gathering space for education, cultivation, celebration and the ordinary exchanges of farm life.

What makes it worth your attention is how little it insists on itself. The architects describe it as a framework rather than a building, and the photographs back that up. The pavilion is a flat roof, a timber frame, a concrete floor and a handful of walls that can slide, pivot or stay put. The program is left almost entirely to the people using it. The design succeeds by doing a few things precisely and then getting out of the way.

Arriving Through the Meadow

Seen from across the field, the pavilion reads as a low horizontal line beneath the grasses and the gnarled limbs of the surrounding trees. It does not compete with the landscape for height. A timber boardwalk threads through the planting toward a gap in the fence, so the approach becomes a short walk through the working farm rather than a step off a parking lot.

The straight-on view makes the logic plain: a slab, a roof, picnic tables in between. This is agricultural architecture in its most legible form, and we think that is the point. Anyone who has stood under a hay barn or an equipment shelter will understand the building immediately.

A Roof That Does Most of the Work

The roof is the pavilion's main gesture. It cantilevers well past the enclosure on slim timber posts, throwing a deep band of shade over the gravel path and creating a covered threshold before you are technically inside. In the Petaluma climate, with its bright dry summers and wet winters, that overhang is not decoration. It shades in the heat and keeps the edges usable in the rain.

Small details reinforce the agricultural reading. A rain chain at one corner turns runoff into something visible, a reminder that water on a farm is a resource to be directed rather than hidden in a downpipe. The exposed beams carry the roof with no pretense of lightness. You can see exactly how the building stands up, which suits a place designed partly for teaching. CFBR served as structural engineer.

Walls That Slide, Pivot and Stay Open

The enclosure is built from a short vocabulary of parts: glass walls, sliding timber panels and a pivoting wood door. Together they let the pavilion change state over the course of a day or a season. Closed, it becomes a sheltered room. Open, it dissolves into a covered porch with the grasses running right up to its edges.

This adjustability is where the framework idea becomes architecture rather than a slogan. The building does not require a fixed answer to the question of what it is for. A morning workshop, a long dinner and a quiet afternoon break each get a different configuration of the same wall.

Under the Beams

Inside, the material palette stays honest. Heavy timber beams sit beneath a corrugated roof deck, and picnic tables rest on a plain concrete floor. Nothing here is precious, which matters in a building that will see muddy boots, harvest crates and folding chairs. The corrugated underside nods to the metal-roofed sheds found on working farms across Northern California without turning that reference into a costume.

In low sun, light slips under the overhang and across the floor, and the grasses outside the glass become the room's real backdrop. The figure walking through the space in the three-quarter view gives a sense of scale: generous enough for a crowd, but still roughly the size of a large living room.

Weathered Edges and Long Light

The vertical board walls and cedar cladding are already taking on a weathered tone, and the design seems to welcome that. A band of clerestory glass runs above the solid walls, so daylight enters high while the lower walls give privacy and a sense of enclosure. The effect is a roof that appears to hover over a solid base.

Framed by an olive tree at dusk, the elevation shows how carefully the proportions are tuned. The horizontal roof, the vertical boards and the thin strip of glass between them produce a calm composition from very ordinary parts. Restraint like this is harder than it looks.

A Lantern After Dark

At dusk the pavilion changes character. The lit ceiling and floor turn it into a lantern in the fields, and the tables become a stage for whatever gathering happens next. For a farm that hosts dinners and celebrations, this evening identity is not a side effect. It is half the building's life.

The glowing underside of the roof also explains the choice to leave the structure exposed. Lit from below, the beams and corrugated deck give the space texture and rhythm without any added ornament.

Plans and Drawings

The axonometric series is the clearest argument for the project. Rather than a single idealized view, the architects draw the same frame four times: unoccupied, set for a farm-to-table dinner, arranged for a harvest festival and cleared for a yoga class. The architecture stays constant while furniture and bodies redistribute around it.

We would like to see more architects present small community buildings this way. Drawing use rather than form makes the design's flexibility testable, and it shows that the slatted wall, the low bench and the small gabled neighbor are all active parts of how the space gets inhabited.

Why This Project Matters

Small rural buildings are often where architecture either overreaches or gives up. The Live Oak Farm Pavilion does neither. It takes the familiar typology of the farm shelter and refines it with a deep roof, adjustable walls and carefully proportioned elevations, producing a space that works for both a classroom and a celebration without needing to look like either.

Its broader lesson is about modesty as a design strategy. By treating the building as infrastructure for community life rather than an object to be admired, Austin Sandy Architects gives the farm something more durable than a statement: a reliable, open frame that the people who use it will keep redefining for years.
