Luxury Construction in Key Biscayne
Island building is its own discipline. On Key Biscayne, every project answers to flood maps, salt air, storm surge, and a single causeway for every truckload of material — which is why the Village's homeowners hire Xpert Construction Group, the island's leading licensed design-build contractor. We plan logistics as carefully as architecture, keeping crews productive and neighbors undisturbed on an island that values its quiet.
Backed by Florida license CRC 1335930 and 25+ years of combined experience, we deliver waterfront home remodeling and ground-up custom home construction engineered for coastal exposure: elevated foundations, impact-rated envelopes, and materials chosen to shrug off salt and humidity. Interiors get equal rigor, from full condo renovations to estate kitchens. Read why island homeowners choose Xpert — then let's walk your property together and talk honestly about scope, budget, and schedule.
Building in Key Biscayne: Local Knowledge Matters
Key Biscayne pairs two very different housing markets: oceanfront condominiums along the Atlantic side — including the Key Colony and Ocean Club communities — and single-family neighborhoods threaded with canals and bayfront lots on streets like Harbor Drive and around Mashta Island, where older ranch homes are steadily giving way to elevated new construction. Much of the island lies in AE and VE flood zones, so substantial renovations trigger FEMA substantial-improvement math and new homes are built well above base flood elevation. The Village of Key Biscayne runs its own Building, Zoning and Planning Department, and all envelope work must satisfy Miami-Dade High-Velocity Hurricane Zone product approvals — both realities we engineer for from the first site visit.What we build in Key Biscayne
Our Services in Key Biscayne, FL
Custom Home Building
New Key Biscayne homes are built up as much as out — elevated living levels above flood elevation, ground floors designed to code for parking and storage, and structures engineered for HVHZ wind loads and salt exposure. Xpert handles the full design-build arc: architecture, coastal engineering, Village permitting, and construction with island logistics managed daily.
Custom Home Building →Home Remodeling
Remodeling on the Key ranges from refreshing an Ocean Club residence to gut-renovating a 1970s canal-front ranch. We navigate FEMA substantial-improvement rules candidly — telling you when a renovation makes sense and when rebuilding is smarter — then execute with marine-grade materials, impact glazing, and Village permits handled entirely in-house.
Home Remodeling →Kitchen Remodeling
Island kitchens earn their keep: school mornings, boat-day lunches, and season-long entertaining. We build them with custom cabinetry sealed against humidity, stone counters, and ventilation sized for serious cooking, opening walls to water views where structure allows — with Key Biscayne permits, engineering, and condo association coordination all managed by our team.
Kitchen Remodeling →Home Additions
On canal and interior lots, additions let families expand without leaving the island: new wings, elevated second stories, and outdoor living structures engineered for High-Velocity Hurricane Zone conditions. Xpert checks flood-zone implications before design begins, then carries plans through Village of Key Biscayne review and builds with disciplined scheduling.
Home Additions →ADU Construction
Where Village zoning allows, a guest cottage or garage conversion gives Key Biscayne households flexible space for visiting family and seasonal guests. We assess your lot's coverage, setbacks, and flood-zone constraints honestly, then design, permit, and build a self-contained accessory space finished to the same coastal-grade standard as the main home.
ADU Construction →Key Biscayne Construction FAQs
How do flood zones affect remodeling on Key Biscayne?
Much of the island sits in mapped flood zones, so major renovations are measured against FEMA's substantial-improvement threshold — exceed it, and the whole home must be brought to current elevation and code. Xpert runs that analysis early so you know whether to remodel or rebuild before spending on design.
What does construction cost on Key Biscayne?
Island logistics, coastal engineering, and flood compliance put Key Biscayne at the premium end of typical South Florida ranges: significant remodels commonly reach the mid six figures, and new elevated custom homes price in the millions. We provide a fixed, itemized proposal after design and site review.
How long do Village of Key Biscayne permits and construction take?
Design, engineering, and Village permitting for major work typically run three to six months, with construction adding roughly six months for large remodels and twelve to eighteen for new homes. Barging in mindset if not in fact — every delivery crosses one causeway — we schedule materials early to avoid idle weeks.
Do you work in the island's condominiums as well as houses?
Yes. We renovate residences in Key Colony, the Ocean Club, and other oceanfront communities — managing association approvals and building logistics — and we remodel and build single-family homes across the Village, from Harbor Drive and Mashta Island to the interior streets.
