Home Addition Contractor in Boca Raton, FL

When Experience Matters

More Space. More Life. No Need to Move.

Your home is in the right neighborhood, on the right street, in the community you love. But somewhere along the way, it stopped fitting the way you live. A growing family, aging parents moving in, or simply the desire for more space — a thoughtfully designed home addition is the answer.

Bluestone Contractors is Boca Raton’s premier design-build home addition contractor, delivering seamlessly integrated expansions across the country club communities to the coastal estates of Boca Raton. We don’t just add square footage — we extend the architecture, character, and flow of your existing home with the high-end finishes and craftsmanship that Boca Raton’s finest residences deserve.

Remodeling or Addition — What’s the Right Solution?

Remodeling means reconfiguring or repurposing space you already have. It’s the right choice when your footprint is sufficient but your layout isn’t working.

An Addition or Extension means expanding your home’s footprint or envelope — a new wing, a second story, a primary suite, or a seamlessly connected living space. It’s the right choice when you’ve outgrown what you have.
Bluestone’s design-build process evaluates both before recommending either. Sometimes the best addition is no addition at all — just a smarter use of what’s already there.

One of Six

We believe exceptional work requires exceptional attention. That’s why Bluestone limits our practice to a maximum of six major remodeling projects per year. When you choose Bluestone for your home addition, you are one of six families who will receive our complete focus — from the first design meeting to the final punch list.

Spaces are limited. If you’re planning a home addition in Boca Raton, we’d love to hear about your project.

Frequently Asked Questions

What is the difference between a home addition and a home renovation?

A renovation refreshes the existing footprint — new finishes, fixtures, or surfaces without adding square footage. An addition extends the footprint: new square footage added to the structure, requiring architectural design, structural engineering, permitting, and construction. Additions are among the most complex residential projects because the new space must integrate seamlessly with the existing structure, roofline, and exterior. Bluestone's design-build team specializes in additions that look and feel as though they were always part of the original home.

How much does a luxury home addition cost in Boca Raton?

Luxury home additions in Boca Raton range from $300 to $600+ per square foot in 2026. A 500 sq ft primary suite addition at the luxury tier typically runs $150,000–$300,000+. Second-story additions and those incorporating premium outdoor living elements run toward the higher end. Bluestone provides a project-specific estimate after an initial site assessment and design consultation with our team.

What permits and approvals are required for a home addition in Palm Beach County?

A home addition requires building, structural, mechanical, electrical, and plumbing permits. If your home is within the City of Boca Raton, or in another Palm Beach County municipality or unincorporated area, permits are coordinated through the appropriate local or county building department. HOA architectural review committee (ARC) approval is typically required before permit applications are filed. Bluestone manages both the permit and HOA submission processes.

How do I make sure a home addition looks like it was always part of the house?

This is fundamentally an architectural challenge. Our design team studies your home's existing proportions, rooflines, exterior materials, window configurations, and interior details before designing the addition. The goal is to make the connection point disappear — matching exterior materials, maintaining consistent ceiling heights and trim profiles, and designing the floor plan so the addition flows naturally from the existing layout. Additions that look like additions are usually the result of design that wasn't design focused-led from the beginning.

Can I add a second story to my home in Boca Raton?

In most cases yes — but it requires structural engineering to confirm your existing foundation and framing can support the addition, a full building permit through the correct jurisdiction, and potentially HOA approval. FEMA flood zone designation may also affect requirements for properties in Palm Beach County's coastal areas. Second-story additions are among the most structurally complex residential projects and require close collaboration between our design-build team and structural engineers. Bluestone can assess feasibility for your specific home.

What HOA restrictions affect home additions in Boca Raton communities?

Common HOA restrictions include: maximum height above the roofline, setback requirements, exterior material and color restrictions, roof pitch requirements, and square footage limits. Communities like Boca West, Broken Sound, and Royal Palm Yacht Club have detailed architectural standards that must be met before permits are filed through the City of Boca Raton or the appropriate Palm Beach County jurisdiction. Bluestone reviews your governing documents before any design begins.

How does Bluestone ensure my addition matches my home's existing architecture?

Our design team conducts a thorough analysis of your existing home before design begins: roofline geometry, exterior material sourcing, window proportions, interior millwork profiles, and ceiling heights. We source matching or complementary exterior materials, coordinate with your existing roof structure, and design the floor plan so transitions between old and new construction feel intentional. The result is an addition that enhances the home rather than looking like a box attached to the back of it.

Will a home addition increase my property value in the Boca Raton market?

The right addition can significantly increase property value — particularly primary suite additions, kitchen expansions that improve the home's flow, and additions that create outdoor living connections. The key is ensuring the addition aligns with what buyers at your price point expect. Over-building relative to neighborhood comparables limits your return. Bluestone provides guidance calibrated to your specific market and street to develop a seamless end product.

How long does a home addition take in South Florida from start to finish?

From contract signing to completion, a luxury home addition typically takes 6–12 months: 4–6 weeks for design and engineering; 4–8 weeks for HOA approval (if required); 4–8 weeks for permit processing through the correct jurisdiction; 2-3 months for design and working drawings, and 3–6 months for construction. Bluestone submits HOA applications and permits in parallel with design finalization to compress the pre-construction period.

How does Bluestone manage a home addition without disrupting my daily life?

We plan the construction sequence to minimize disruption to occupied areas. Exterior work, foundation, and framing are sequenced before interior tie-ins wherever possible. We maintain clean job sites, establish dedicated contractor entry and exit points, and protect occupied areas with proper containment. For tie-ins to existing living spaces, we schedule those phases strategically and complete them as quickly as possible. The remodel-level disruption of a tie-in is temporary; the benefit of the new space is permanent.

What if my Boca Raton property is in a flood zone — does that affect my home addition?

Flood zone designation is one of the first things Bluestone evaluates before any design work begins. A large portion of Boca Raton lies within a FEMA-designated Special Flood Hazard Area, and updated flood maps that took effect December 20, 2024 increased base flood elevations for more than 16,000 parcels across Palm Beach County. If your property is in a flood zone, Florida’s FEMA 50% Rule may apply. Bluestone conducts a full flood zone and slab elevation analysis before recommending any scope of work.
