Mar Vista House in Los Angeles by PPAA: Subtractive Design and Patio Living

Design Intent and Architectural Concept

Mar Vista explores the expressive potential of geometry in residential architecture. The design establishes a measured dialogue between straight and curved lines that produces spatial tension and character while supporting a fluid relationship with the landscape.

The project builds on a preexisting arrangement composed of a central rectangular volume and two patios at the front and back. Within the site’s maximum allowable building area, the architects used subtraction to create voids that recalibrate the program and amplify the role of outdoor rooms. This operative removal increases permeability, daylight, and environmental responsiveness without expanding the footprint.

A curved roof reinterprets the traditional gable within local height and design regulations. The primary entrance shifts to the side, keeping the principal façade visually open to the front patio and reinforcing the continuity between the interior space and the exterior threshold.

Spatial Organization and Circulation

Two distinct volumes organize the program. The main two-level block concentrates social functions on the ground floor, including a living room, dining area, kitchen, guest toilet, and a semi-covered terrace. The upper level contains the private realm with a primary bedroom, three secondary bedrooms, three full bathrooms, and a studio.

A second single-story volume at the rear contains the guest quarters with a bedroom, full bathroom, and kitchenette. This separation provides autonomy while preserving proximity to the main house.

Front and rear patios act as spatial anchors that structure movement and views. Large openings create cross-readings across the plan and elevate the patios from residual space to primary living territory. Apertures are aligned to encourage cross ventilation and daylight, while surrounding vegetation contributes to microclimatic comfort and visual depth.

Material Strategy and Construction

The interior palette combines oak wood and polished concrete to produce a luminous and calm atmosphere. Wood introduces warmth and tactility. Concrete contributes durability and a refined surface continuity that suits both social and private programs.

The exterior employs artisanal striated plaster that captures light and shadow, adding depth to the envelope and a clear identity at the scale of the street. Large glazed openings are proportioned to preserve transparency while balancing privacy and environmental control.

The roof’s curvature required careful geometric resolution. Its profile mediates between vertical enclosure and horizontal span while remaining within regulatory limits, turning compliance into an opportunity for formal clarity.

Contextual and Theoretical Significance

Mar Vista situates itself in the discourse on permeability in domestic architecture for warm, temperate climates. The project treats the boundary between inside and outside as a continuous field that adapts to use, climate, and time of day. This approach resonates with patio-centric traditions in Southern California while updating them through precise openings, material restraint, and a contemporary roof form.

The work demonstrates how voids can carry the same architectural weight as built mass. Subtraction becomes a primary design instrument that reorganizes the program and intensifies environmental performance in a constrained suburban lot.

Typologically, the house shows that innovation can coexist with strict planning parameters. The interplay of geometry, environmental strategy, and programmatic clarity offers a model for residential projects that seek open spatial systems without sacrificing regulatory compliance or construction pragmatics.
