Projects

Explore completed projects by Design & Construction by M&M, a Bay Area design-build contractor specializing in home additions, ADUs, garage conversions, and major residential renovations.

Our portfolio includes projects throughout Palo Alto, San Francisco, Menlo Park, Los Altos Hills, Sunnyvale, Belmont, and surrounding Bay Area communities. Each project reflects the homeowner’s goals, the character of the existing property, and the unique planning and construction requirements of the site.

Additions and Major Home Renovations

Many of our projects involve expanding and reimagining existing homes to create more comfortable, functional living spaces. Our past work includes room additions, multistory additions, kitchen expansions, structural layout changes, and complete home renovations.

Rather than treating the addition as a separate structure, we carefully consider how the new space will connect with the home’s existing architecture, layout, and finishes. The goal is to create an expansion that feels like a natural part of the property while improving how the home works for the people living there.

ADUs and Garage Conversions

Our ADU projects include detached backyard units, attached living spaces, above-garage ADUs, and garage conversions. These projects have helped Bay Area homeowners create flexible space for multigenerational living, visiting family, private guest accommodations, home offices, and potential rental income.

Every property presents different opportunities and constraints. Lot configuration, utility access, parking, setbacks, structural conditions, and city permitting requirements all influence the final design.

Designed and Built Around Each Property

No two Bay Area homes are exactly alike. Older properties, compact urban lots, hillside conditions, and local building requirements can make larger residential projects especially complex.

As a full-service design-build company, Design by M&M helps homeowners coordinate the major stages of their project—from initial planning and design through permitting, construction, and the final walkthrough. Browse our completed projects below to see how we have helped homeowners expand, renovate, and improve their properties through thoughtful design and quality craftsmanship.
