Frequently asked questions
Do I need an architect for an addition?
For most additions we coordinate the drawings and engineering ourselves. For larger or complex projects we bring in an architect and manage that work as part of the job.
How long does an addition take?
Most additions take a few months from permit to final walkthrough, depending on size and town permit timing. Your proposal includes a schedule.
Can you match my existing siding and roof?
Yes. We match siding, trim, and roofing to the existing house so the addition looks like it was always there.
