House O, designed by Jun Igarashi, forgoes hallways and interior doors in favor of casually interconnected rooms.

Sleeping nooks that look like the grooves in a block of cheese.

Architect: YAMAMAR Design, Location: San Francisco, California

Tasked with creating a multi-use guest pavilion on a relatively small Northern California vineyard lot that could also host sit down dinners for up to 60 people, designers at Anderson Architects started by asking the key questions: “Where should it be within the property?” “How much floor area do we need for a 60 person dinner?” “How much volume do we need for a basketball court?” “We also always tell ourselves to look at the landscape first, let it dominate and lead it through. The building took the form of a large Napa Valley barn.

A passage between the walls for hide and seek.

The addition’s two stories of cedar-framed sliding doors and window provide generous views of the house’s prized jacaranda tree. The addition’s polished concrete floor and white cladding extend into the garden, drawing occupants to the serene rear porch. There, they can relax on stools designed by Alvar Aalto and Charles Wilson while admiring the luscious greenery.

Situated on a sloped-site, each renovated space provides a unique perspective and vista to the dramatic natural surroundings. The office, with its stark modern furnishings and subtle artwork, allows the large window to serve as perhaps the most dramatic, singular frame to the foliage beyond.

This living/bedroom space showcases neutral tones and shades of white to contrast the continued use of natural, treated wood surfaces.
