Transform Your Home with Seamless, Purpose-Built Expansion

At Finish Carpentry Design, we don’t just add space—we design it to belong. Our home additions and extensions are thoughtfully crafted to complement your home’s existing structure, architectural character, and lifestyle needs. 

Whether you’re looking to expand your living area, add a sun-filled family room, or build a custom office or in-law suite, we bring your vision to life with precision and elegance.

Room Additions – More space. More function. More value.

Room additions are one of the most impactful ways to enhance your home’s functionality and comfort. We specialize in:

We ensure every detail of your addition—from the roof tie-in to the final trim—blends perfectly with your home’s original build. We use only high-quality materials and work under architect-certified plans that meet or exceed local building codes. HVAC integration, foundational work, and finishing carpentry are all handled in-house to ensure a clean, unified result.

Bump-Outs & Extensions

Want to extend your kitchen, expand a bathroom, or add space to a primary suite? Our architectural bump-outs and horizontal extensions offer big impact with minimal disruption. These smaller-scale additions maximize usable square footage and are often completed faster than full-scale room additions.

Common bump-out and extension services include:

We handle everything from foundation to framing to finish trim—ensuring your extension feels like it’s always been part of the home.
