Home Additions

It depends on the foundation and framing the footprint needs, whether the roofline ties in or extends, and how far the systems have to reach. Structural engineering and plan-check add to it. We scope it on site and price it in writing.

Home additions require building permits, structural engineering approval, and drawings reviewed by the local building department. We prepare the drawings and manage the permit process from submission through final approval, with a licensed engineer stamping what the city requires.

Most home additions take 3-7 months depending on square footage, structural scope, and permitting timelines.

Yes, that's the core of how we design additions: matching materials, rooflines, and proportions so the new space reads as original to the home rather than a bolt-on.

Building out is usually cheaper per square foot, because a second storey needs the existing foundation and framing checked and often reinforced, plus a stair that costs you floor area on both levels. Building up wins when the lot has no room left, or when setbacks and lot coverage limits close off the ground.

Usually, until the connection. Most of an addition is built outside the existing envelope, so the disruption stays outdoors. The exception is the week the wall comes down to join the two, which is loud, dusty and worth planning around.

A ground-floor addition needs its own foundation, and it has to be tied to the existing one so the two settle together. A second-storey addition uses the foundation you have, which is why it gets inspected and sometimes reinforced first.
