Design that survives the budget
We price the drawings while they are still editable. If the roof geometry, window package, or foundation approach is driving cost past your target, you hear it during design — not after the slab is poured.

Custom home building
A house built to your drawings, not a catalog
Trinity Home Construction builds custom homes on infill lots and acreage throughout South Seattle, Skyway, Renton, and the greater Puget Sound area.
What's included
- Architect and structural engineer coordination
- Fixed-scope estimating with allowance transparency
- Energy-code compliance and inspection management
- Finish carpentry, tile, and cabinetry in-house
Daily supervision on site
A Trinity superintendent is on your lot every working day. Framing tolerances, waterproofing details, and rough-in coordination are inspected as they happen, which is why our punch lists are short.
