Reviews

What San Jose homeowners say.

"They lifted our 1970s ranch and added a master suite above the garage. The new staircase lines up perfectly with the hallway, and the stucco matches like it was always there."

David R.
Second-Story Addition

"Our 900 sq ft ADU went from permit to move-in ready in five months. The rental income is already covering the loan payment."

Lisa M.
Detached ADU

"The kitchen layout was awkward for decades. They removed a wall, rerouted the gas line, and installed an island where we cook every night now."
