Need more space but love your location? A home addition lets you expand your living area without the hassle and expense of moving. Westerly Ventures builds additions that seamlessly integrate with your existing home — from single-room bump-outs to full second-story additions.

We specialize in second-story additions, room additions, ADU and DADU construction, garage conversions, and sunroom enclosures. Our design-build approach ensures the new space matches your existing home’s architecture, roofline, and interior finishes for a cohesive look.

Every addition project includes structural engineering, permit management, foundation work (if needed), framing, roofing tie-in, siding match, and complete interior finishing. We handle the complexity so you can focus on enjoying your new space.
