Step 1 of 6

When you love your neighborhood but need more space, a home addition is the answer. Locali Builders designs and constructs additions that integrate seamlessly with your existing home - matching rooflines, exterior materials, and architectural character so the new space looks like it was always there.

Common additions include primary suite expansions, second-story builds, family room extensions, sunrooms, bonus rooms, and in-law suites. We work with structural engineers to ensure your foundation and framing can support the addition, and we handle all architectural plans and city permits.

The design phase is critical. We study your existing home's architecture, materials, and style to create an addition that flows naturally. Interior ceiling heights, flooring transitions, HVAC ductwork routing, and electrical load requirements are all planned in advance to avoid costly surprises during construction.

Most home additions take 3-5 months from permit approval to completion. We provide a fixed-price contract after the design phase so there are no budget surprises. Our team handles every aspect of construction including foundation, framing, roofing, windows, electrical, plumbing, HVAC, insulation, drywall, and all interior finishes.
