Standard ADU

All five very standard Accessory Dwelling Unit (ADU) plans, pre-approved by the City of LA Department of Building and Safety (LADBS)
Year: 2021
Location: LADBS, Los Angeles, CA
First Office Team: Anna Neimark, Andrew Atwood, Robert Sipchen
In collaboration with Matt Melnyk, S.E., Principal, Nous Engineering


A very standard ADU, interior renderings
The Accessory Dwelling Unit (ADU) developed for the City of LA is built using prefabricated Structural Insulated Panels (SIPs). The panels’ laminated structure, a sandwich of foam insulation and Oriented Strand Board, allows for expedited construction schedules and offers high environmental ratings, producing great value for home owners.


Plan A: two-bedroom standard plan, pre-approved by the Department of Building & Safety.
Plan A model isometric.

There are five possible plans presented, all derived from Plan A, with the maximum allotted 1,200sf footprint occupying four quadrants. Plan B is an L-shaped plan that preserves three quadrants from the overall layout. Plans C and D span across two adjacent quadrants. And Plan E offers the most efficient studio, occupying just one quadrant. This permutation of one plan into five different footprints allows owners to find a design for their desired size.


Plan B: one-bedroom standard plan, pre-approved by the Department of Building & Safety.

Tucking the infrastructural and mechanical programs (such as closets, built-in shelves, kitchen counters and bathrooms) into the vertical SIP supports, the house follows an efficient and open plan. While the design of the ADU is minimalist in its form and expression, it maximizes the materials’ environmental performance, taking into account sustainability factors and flexibility of construction, as well as SoCal’s indoor/outdoor lifestyle. The house has a seamless relationship with its backyard and the main house through large windows and sliding doors and offers an opportunity for a roof deck above.


Plan C: studio standard plan, pre-approved by the Department of Building & Safety.

In collaboration with Nous Engineering, the designs merge structure and comfort through an open plan, organized by utilitarian structural closets and built-ins. The interior finishes include painted SIPs and gypsum, concrete floors, stainless steel counters, and an occasional element of conduit. We kept things intentionally minimal and artfully detailed.


Plan D: another studio standard plan, pre-approved by the Department of Building & Safety.

Plan E: minimal standard plan, pre-approved by the Department of Building & Safety.
Plan E model isometric.

First Office was founded in 2011 by Anna Neimark and Andrew Atwood to create a dialog between architectural practice and academic discourse. Their collaborative work spans buildings, exhibitions, and publications, all rooted in the belief that architecture is a form of cultural production.
The practice has engaged with leading institutions, including the MAK Center for Art and Architecture, the Chicago and Venice Biennials, MoMA PS1’s Young Architects Program, and the Architectural League of New York. The projects and essays of First Office have been recognized with awards and compiled in Nine Essays (Treatise Press, 2015), as well as in Andrew’s publication Not Interesting: On the Limits of Criticism in Architecture (Applied Research and Design, 2017).
