Featured custom home

A 10,308 sq ft modern home in Riverside

Smooth stucco, wood cladding, a metal roof and walls of angled windows and doors, designed by Xavier Design Group. It is the largest home we have finished.

Before framing, we put the design team, the steel subcontractor, the framer, the window installer and the supplier in the same meetings, so the glass went in right the first time. Inside, every room has custom cabinetry, from the three-island kitchen under a wood ceiling to the primary bath with a freestanding tub.

Featured ADU

An 893 sq ft ADU and pool house in Fontana

Phase one was the unit itself: a stone-faced gable, French doors to the pool deck, and a kitchen with navy cabinets and a white waterfall island, finished with interior designer 8a Interiors.

Phase two finished the backyard around it: an outdoor bathroom and shower with a pebble floor, storage rooms, a trash enclosure and two pergolas.

Jimmy and his team did an amazing job with our patio cover. The work was very professional and looks amazing! Many people in the community have remarked upon how great it looks and have even asked for a referral. The work was completed in a timely manner and done to our complete satisfaction. I highly recommend him if you are thinking about doing any additions or ADUs!
