Additions need the same rigor as new construction: foundation, envelope, mechanical tie-ins, and matching finishes. We design the build plan so the existing home stays protected.

We handle

  • Second-story and rear additions
  • ADUs and detached structures
  • Garage conversions done correctly
  • Envelope and waterproofing details
