Documents that make building straightforward.

Tying new space into an existing home is where projects go wrong. Our construction background means the structural tie-ins, rooflines, and window configurations are drawn to build — so your contractor bids with confidence instead of padding for the unknown.

  • Custom fireplaces, built-ins & complex window walls
