Home Additions
Design by M&M helps Mountain View homeowners create more functional living space through carefully planned room additions. As a design-build contractor serving Mountain View, Santa Clara County, and the greater Bay Area, we manage the entire process — from early design and feasibility through permitting, construction, and final walkthrough.
Mountain View sits in the heart of Silicon Valley, and demand for housing here reflects it. For homeowners, that often means the smartest path to more space isn’t a bigger house across town — it’s expanding the one they already own. Much of Mountain View’s housing was built in the 1950s and 60s, including the city’s well-known Eichler neighborhoods, and those original floor plans often need updating to serve modern family life.
Additions in Mountain View come with their own considerations — lot sizes that vary widely by neighborhood, mid-century construction methods, and city planning requirements — and our team helps you understand what your property can support before design work ever begins.
Accessory Dwelling Units (ADU)
We specialize in turning underused garages into comfortable, fully permitted living space. Serving Mountain View and nearby communities, our team helps homeowners expand what their property can do — without changing the footprint of the home.
Popular garage conversion projects include:
- Converting a garage to an ADU for rental income or family use
- Creating a home office or studio for remote work
- Adding a guest suite or flexible bonus room
Garage conversions often look simple from the outside, but they involve real construction and compliance work: insulation, electrical upgrades, plumbing (for ADU conversions), egress requirements, and city permitting. We manage those details from the start, so the finished space is safe, legal, and built to last.

Design Build
As a remodeling company in Mountain View, we focus on larger renovation projects that improve how a home functions — not just how it looks. Many Mountain View homes still reflect their original mid-century designs: closed-off kitchens, smaller bedrooms, and layouts that separate rather than connect. Our home remodeling services help homeowners open up living areas, modernize aging systems, and improve flow throughout the home.
Our remodeling services include:
- Whole house renovation — comprehensive updates to layout, systems, and finishes
- Kitchen remodels — typically as part of larger layout improvements or expansions
- Major renovations — reworking floor plans, removing walls, and modernizing older homes
- Renovation paired with additions — improving the existing home while adding square footage
Our remodeling process follows the same design-build structure as our additions and ADU work: feasibility first, then design, budget alignment, permitting, and construction — all managed by one team with clear communication throughout.
