Questions
Room Addition FAQ
Is a room addition worth it compared to moving?
With today's mortgage rates, adding space to a home you already own is often far more economical than selling and buying larger. An addition also lets you design exactly the space you need instead of compromising on someone else's floor plan.
How long does a room addition take?
A single-room addition typically takes 3–5 months of construction after permits; larger additions and second stories take longer. Design and permitting before construction usually add 2–4 months.
Will the addition match my existing home?
That's the goal — and the craft. We match rooflines, siding, windows and interior finishes so the addition reads as original to the house, not bolted on.
Do you handle the permits and engineering?
Yes. Additions require architectural plans, structural engineering and city permits — we manage all of it, including inspections, as part of every project.
