The scope, plainly.
Additions are about extending a house without breaking its character. The structural moves matter — a beam in the wrong place, a roofline that doesn't quite line up, and the addition reads as an afterthought. We pay attention. Most of our additions are family-driven: a second bath for teenagers, a primary suite that finally has its own door, a mudroom that handles Pacific Northwest winters. We coordinate the structural design, weather-tie the new envelope to the old one, and finish so the join is invisible.
