Home Additions in Sunnyvale
Room additions and second stories that look like they were always there.
Trusted home additions for Sunnyvale homeowners
When Sunnyvale homeowners need home additions, they call VDC Construction. Sunnyvale's Eichlers and mid-century ranches are constantly being opened up and modernized, and the area's growth means additions and ADUs pencil out. We handle the design and permitting these projects require.
The mark of a great addition is that nobody can find the seam. We match rooflines, siding, stucco texture, and window styles to your existing home, and we handle the structural engineering, foundation work, and Title 24 energy compliance that additions in California actually require.
Primary suites, family rooms, home offices, and second-story additions — from design and permits through the final coat of paint, one accountable team.
We work throughout Sunnyvale — from Cherry Chase, Ortega Park, Birdland, Heritage District, Ponderosa to the homes near Downtown Sunnyvale and Las Palmas Park. Because we've served Santa Clara County for over 11 years, we know the area's homes, common system types, and what Sunnyvale's climate demands of them.
