How long does a home addition take?
Most room additions take two to four months from permit approval, with timeline driven by foundation work, framing, roofing, and interior finish sequencing. Second-story additions or projects with significant square footage run four to six months. We build a phase-by-phase schedule into your contract with milestone dates so expectations are clear and trackable from day one.
Will the addition match my existing home?
Yes. We source matching siding, roofing, trim profiles, and window styles so the addition reads as original to the house rather than bolted on. Our architects review the exterior elevations and roofline integration before framing begins. Interior transitions (flooring, ceiling height, trim details) are also designed to flow seamlessly between the existing structure and the new space.
