Project Overview

Project: Brentwood

Location: West Los Angeles, CA

ADU Type: Detached Garage Conversion

Scope: Studio / Full Bathroom / Kitchen

Project Goal: Mother-in-Law Suite

Final Result: Completed Mother-in-Law Suite


The Brentwood project involved converting an existing detached garage into a functional residential space. The planned scope transformed the structure into a studio equipped with a full bathroom and kitchen to serve as a mother-in-law suite.

Giving an Existing Garage a New Purpose

Rather than constructing an entirely separate new structure, this project focused on making practical use of an existing detached garage.


The client's goal was to convert the space into a mother-in-law suite with the essential residential features needed for the intended use. The resulting scope included an open studio configuration along with a full bathroom and kitchen.

An Existing Foundation Created a Challenge

Conversions involving existing structures can introduce conditions that are difficult to fully anticipate before construction begins.


During the Brentwood project, the team discovered that the existing footings were not as predicted. This created a structural challenge that needed to be addressed while considering the existing setbacks.

Reinforcing the Existing Footings


To respond to the unexpected condition, the team reinforced the existing footings.


This solution allowed the project to maintain the existing setbacks while addressing the footing conditions discovered during the conversion.

From Detached Garage to Completed Suite

The Brentwood project demonstrates the additional considerations that can arise when converting an existing structure.


Instead of working from entirely new construction, the team had to respond to existing structural conditions while moving forward with the intended garage conversion. Reinforcing the footings provided a path for maintaining the existing setbacks and completing the planned residential space.


The final result was a completed mother-in-law suite with a studio layout, full bathroom, and kitchen.

Project Highlights

Detached Garage Conversion

An existing detached garage was converted into residential space.

Studio Layout

The project was planned as a studio rather than a multi-bedroom configuration.

Full Bathroom & Kitchen

The converted space included both a full bathroom and kitchen.

Mother-in-Law Suite

The client's goal was to create a dedicated mother-in-law suite on the property.

Unexpected Footing Conditions

The existing footings were found to differ from what had been predicted.

Structural Reinforcement

The existing footings were reinforced to allow the project to maintain the existing setbacks.

Completed Conversion

The final result was a completed mother-in-law suite.

Working With Existing Property Conditions

The Brentwood project highlights why conversions can require a different approach from ground-up ADU construction.


Existing structures may reveal conditions that were not anticipated before work began. In this case, the footing conditions required the team to adapt the construction approach and reinforce the existing foundation while preserving the setbacks.


It is an example of the property-specific problem-solving that can become necessary when adapting an existing structure for a new residential use.
