One Team. One License. One Point of Accountability.

You love the neighborhood. You don't love feeling like you'll outgrow the house in two years. Build Serve plans, permits, and builds additions and whole-home renovations across Central Florida — with our in-house design, structural, HVAC, and electrical teams handling every phase of the job. Over 30 years of doing this in Central Florida means we know the soils, the codes, the inspectors, and the HOA design-review committees. That experience shows up in additions that look like they were always there.

Our back door frame was loose, and the door wouldn't shut tight unless we pulled super hard on it. Larry fixed the frame and also installed new moulding around the frame inside and out. Looks great and works great.

Home Additions & Renovations FAQ

Honest answers to the questions Central Florida homeowners ask us most.

How long does a home addition take?

A single-room addition usually runs 3 to 5 months from permit to keys. Whole-home renovations and second-story additions typically run 6 to 9 months. We give you a written schedule before construction starts and stick to it.

Can we live in the home during construction?

Most of the time, yes — we phase the work and seal off active zones. Whole-home gut renovations and second-story additions are the exceptions; we'll talk through the trade-offs at the site visit.

Do you handle the permits and HOA approvals?

Yes. Permits, drawings, structural calculations, and HOA submittals are all part of our scope. You sign, we do the legwork.

Will the addition match the existing home?

That's the goal. Roof lines, exterior finishes, trim profiles, interior moldings — we match what's there so the addition reads as original.

What if we don't have drawings yet?

You don't need them. Our in-house design team produces everything from concept through permitted construction documents.

Are you licensed and insured?

Florida Certified General Contractor (CGC1537508), fully insured. License and insurance details are on every contract.
