We were honored to attend the 55th LABC Awards and accept the Architectural Award in the Renovated Buildings category for our work on The Japanese Institute of Sawtelle.
Reinvesting in culturally significant buildings, especially those with humble origins, is vital not only to preserving Los Angeles’ existing building stock but also to sustaining the cultural legacies of the diverse communities that have shaped the city.

Congratulations to our project partners, Studio SUPERNATURAL and NOUS Engineering, as well as all the nominees and winners!

“This project exemplifies a vision for gracefully renovating Los Angeles’ existing building stock, proposing a radical transformation of a humble yet historically and culturally significant building by introducing a culturally relevant and modern design that honors both the legacy and future of the Japanese American community’s resilience and presence in West Los Angeles.” –LABC

[1 of 3] Evolving Catalog Housing
Interior view of Stack & Step. A research project that looks to evolve the traditional single-family catalog home for medium-density infill housing. Unlike earlier catalog models, which offered fixed floor plans, Stack & Step catalogs a set of pre-defined core elements; each containing a core domestic function. These programmatic blocks can be configured in size, quantity and arrangement making them adaptable to various site conditions, and more significantly evolving models of homeownership.

[2 of 3] Co-buying & Co-Ownership.
Stack & Step explores how infill housing can support evolving ownership and development models. From compact studios to larger multi-bedroom layouts, units may function as independent homes or as a series of spaces be interconnected across courtyards to accommodate families, friends, or multi-generational households. By balancing shared and private spaces, the approach is intended to enable a Threshold/Pre-Sale Model of development to reduce development risk and transfer of that risk to buyers, or as a speculative housing model.

[3 of 3] Discrete Domesticity
In Stack & Step, each grid module is dedicated to a core domestic function such as living, sleeping, cooking, or bathing. Modules can be added, combined, or subtracted to create flexible layouts and support innovative approaches to infill medium density development and ownership.

[1 of 3] Rebuild Approach

Another like-for-like rebuild Good Project Company was engaged for. The rebuild maintains the siting of the original footprint, and seeks to maximize usable space as well as incorporate enhanced hardening strategies, while also retaining the warmth and material richness that characterized the previous home, qualities the client was eager to reference.

[2 of 3] Plan Organization and Site Response.

A series of rammed earth walls organize the plan into five bays punctured by a single-loaded corridor which separates south-facing living areas from the support spaces arranged along the North.

[3 of 3] Elevation Strategy and Outdoor Access

Generous overhangs provide shade and create private patios for living area which face the adjacent creek bed; and operable doors at both ends of the living room allow the space to be enjoyed as an indoor and outdoor area. The primary living spaces are elevated above grade, set above the watershed plain of the adjacent creek bed and a spiral stair leads to a rooftop perch, ideal for stargazing in the canyon.

SideYards > FrontYards
Traditional housing models prioritize articulation of street-facing façades, Stack & Step re-prioritizes attention to the side yards, where impacts on neighbors are greatest. Open spaces and patios are layered strategically to reduce shadows, improve daylight and ventilation, and enhance livability and the quality of ‘shared’ space with adjacent neighbors. This shift supports a more context-sensitive and neighborhood-positive approach to medium-density infill and with the intent of fostering broader community acceptance.

[1 of 2] Rethinking Infill Housing
As part of our internal research, we have been re-examinng how the egalitarian and repetitive nature of post-war housing, central to it’s affordability, can be adptaed to meet today’s diverse housing needs, accommodating a broader range of lifestyles and living arrangements, in ways that are both economical and adaptable; while also evolving a positive model for how higher-density infill development can more effectively integrate into single-family zones.

[2 of 2] Adaptable Density
Stack & Step was developed around a system of repetitive programmatic blocks, each containing a primary domestic function. Blocks can be bundled for combined uses or separated, based on unit type. Their repetitive nature could support panelized, pre-fab, volumetric, standard stick-frame, or hybrid construction, leveraging the strengths of each method, as appropriate, without being limited to any one system.
