Home additions
Orlando, FL

Home addition investment depends on scope — a simple bonus room is a very different project from a second-story addition or a fully plumbed in-law suite that extends your foundation, roofline, and every home system. KBF begins by establishing a target investment together, then aligns the design, engineering, and construction scope to that target. After the in-home consultation and design development, you receive a fixed-scope written estimate before work begins. Any later change is documented and approved in writing before it affects cost or schedule.

KBF builds primary suite additions, in-law suites, second-story additions, sunroom and lanai enclosures, garage conversions, bonus rooms, and bump-outs for kitchens or living spaces. Every addition is engineered to integrate with your existing roofline, HVAC, and electrical, so it reads as part of the original home — not a tacked-on box.

A KBF home addition typically takes 4 to 7 months from contract to final walkthrough — roughly 6–10 weeks for design, engineering, and permitting, and 10–18 weeks for construction depending on size and complexity. Second-story additions and additions over 500 sq ft trend toward the longer end because of structural engineering and inspection sequencing.

Yes — every home addition in Florida requires a building permit, and most require structural engineering drawings, an energy calculation, and a survey showing setback compliance. KBF handles the full permit package — engineering, architectural plans, county/city submittal, and all inspections — so you don’t manage the building department directly. Permitting in Orange County typically takes 6–10 weeks.

Yes, in almost every case. Adding heated/cooled square footage triggers a reassessment by the Orange County (or your county’s) Property Appraiser, and your assessed value will rise to reflect the added space and improvements. The increase is generally proportional to the addition’s value, and most KBF clients find that the resale appreciation and daily use value substantially outweigh the tax impact. We recommend talking to a CPA before signing if the tax piece is material to your decision.

KBF handles design and brings in a licensed Florida architect or structural engineer when the project requires it — second stories, load-bearing modifications, or complex rooflines. That cost is built into the design phase upfront, not added later, so you see the full design investment before construction starts.

Yes — most KBF home additions are designed so the existing home stays fully livable during construction, with the addition built and sealed before we cut into the existing structure. Dust containment, temporary weatherproofing, and protected work pathways are standard. Plan on 2–4 days of disruption when we tie the addition into the existing space (the “break-through” phase).

Late fall through early spring (October through March) is the ideal window to start a Florida home addition, because foundation work, framing, and roof dry-in happen before hurricane season and summer rains. Projects started in late spring or summer can absolutely succeed — KBF builds year-round — but the schedule needs more weather-day buffer. We monitor the forecast daily and adjust the critical-path schedule accordingly.

KBF prepares the full HOA submittal package — site plan, elevation drawings, exterior material and color specs, and any required setback documentation — and submits it on your behalf or alongside you, depending on your community’s rules. We’ve worked with HOAs across Winter Park, Lake Mary, Windermere, Dr. Phillips, Baldwin Park, and other Central Florida communities and know what each board typically asks for. Plan on 2–8 weeks for HOA review, separate from county permitting.

Yes — matching is the standard, not the exception. KBF custom-orders or hand-blends siding, stucco, brick, roof tile, and trim to match your existing exterior, and we tie interior flooring, trim profiles, and paint colors so the addition reads as original. On older homes where exact materials are discontinued, we’ll show you 2–3 close-match options with samples before any are ordered.
