SECRET:garden is a renovation of an existing two-story commercial brick building located in the town of Petaluma. The project converts the existing structure from a chicken hatchery and stable building into a primary single-family residence while preserving the building’s raw, unfinished material quality. The design retains the buildings perimeter masonry walls to create an interior garden courtyard while transforming the remaining interior wood frame it into an elegant, warm, light-filled home.

The new 3 bedroom, 2 ½  bath home and garden is built entirely within the masonry walls – preserving as much of the existing structure as possible.  The remaining diaphragm is sandblasted to expose the open framing on the first floor ceilings while the east quarter of the structure is demolished to create an internal light court – a “secret garden”, within the existing brick walls.

The modern two-story home features, broad grazing, skylights and sliding walls, under a new roof and upper deck, all of which is structurally independent of the exterior UMP walls while supporting them laterally with the new exposed  Alaskan Yellow cedar post and beam “frame”. The new concrete shear walls and slab are exposed and hydronically heated to extend outwards to create a side yard porch or  “engawa” space.  This semi inside/outside area is protected by the overhanging upper floor where an engineered wood radiant floating floor and sliding plywood walls create a cozy and flexible private oasis for the family to “tune’ and as guests or office needs change over time.

This upper floor of  “bleached – white” plywood is an open plan with sliding partitions –  to allow for either bedroom or office configurations of the upper living areas all centered around a large light well roof access which opens onto the planted upper roof deck garden with spectacular views of Petaluma, its agricultural past along the Petaluma Canal.
