Images marked "Architectural rendering" show the designed scheme, not the site; everything else is photography of delivered work.

A turnkey delivery model — rare in Silicon Valley residential

The Bay Area default is GC builds, owner buys materials — and you spend half your weekends on procurement and returns. We deliver turnkey: design, materials, build, furniture and styling under one contract. You skip the half-year detour.

  • One contract covers design, materials and construction
  • Materials sourced through our own pipeline of established suppliers
  • Timeline and budget locked — overruns are on us
  • Warranty and post-handover service stitched in from day one

Eric Sun · 孙天元

A builder who treats every project as a portfolio piece

I'm Eric Sun. I build homes in the Bay Area — whole-home remodels and additions, tear-down rebuilds and new construction. I bring the same attention to every wall and every floorboard.

Good homes are completed by the people who live in them. So we don't just deliver a house — we deliver a place worth coming home to and worth holding for the long term.

About Eric Sun

From a parcel of land to a family at home

Services
Custom Homes & New Builds
A house built from the ground up on your lot, around the way your family lives. Lot and zoning analysis, architectural and structural design, permits, construction and handover — one team, start to finish.
Tear-down Rebuilds
When the existing structure is at the end of its life, or zoning allows a larger house, starting over can make more sense than patching. We handle demolition permits, design, entitlement and construction — and the feasibility assessment compares both paths before you commit.
Remodels
Keep the structure, rework the kitchen, baths, floors, windows and flow for the way you live now. Design, material selection and construction in one place, so you are not the one running to the supplier.
Additions
Growing the house you already have: living space, extra bedrooms, a second storey, a bigger kitchen. We know the Bay Area permit paths, so you gain square footage without tearing anything down.
