Building New on Two Different Lot Types
Inland Lantana lots are typically modest in size, shaped by the original mid-century subdivision pattern, and new construction there usually means replacing an existing block home whose footprint and setbacks largely define what's buildable in its place. There's less room to reimagine the site than there would be on a much larger estate parcel elsewhere.
Hypoluxo Island lots offer more latitude in program and orientation toward the water, but flood elevation requirements shape the foundation and massing more than they would on a standard inland lot, which means the architecture has to answer to the site's flood zone from the earliest concept sketch.
Neither condition leaves much room for a generic floor plan dropped onto the site. Every Lantana lot, island or inland, comes with a specific set of constraints the design has to work with from the outset rather than a set of preferences applied around them later.
Permitting New Construction in Lantana
New construction inland goes through Lantana Development Services for site plan, structural, electrical, plumbing and mechanical permits, with setbacks and lot coverage reviewed against the original subdivision's zoning. On a lot this size, confirming buildable footprint early avoids designing a home the site can't actually accommodate.
On Hypoluxo Island, new construction is squarely subject to current flood elevation standards regardless of what stood there before, since replacing a structure resets the compliance clock. An elevation certificate and base flood elevation documentation are required as part of the permit package, not an optional add-on.
That documentation feeds directly into the foundation design, so we treat it as a design input rather than a permitting formality handled after the architecture is already set on paper and hard to revise without real cost, delay and a round of redrawn structural plans no one wants to pay for twice.
Coordinating Architect, Engineer and Contractor
A new build in Lantana benefits from architect, structural engineer and contractor coordination from the earliest site evaluation, since foundation type, drainage and — on the island — elevation strategy all shape the architecture rather than following behind it. We sit in on that coordination rather than receiving finished drawings after the fact.
On projects like Open Frame House and the Azure Horizon Residence, early coordination between design and engineering kept structural decisions from forcing late changes to the architectural program once foundation work was already underway and the shell was taking shape above it, well past the point of easy revision.
Foundation and Envelope for Flood Zones and Block Lots
On Hypoluxo Island, foundation design typically means elevating the lowest floor above base flood elevation, which affects everything from the entry sequence to how the ground floor is used, since space below that elevation is restricted in what it can enclose. Geotechnical evaluation confirms soil conditions before foundation type is finalized.
Inland, foundation work is more conventional, though replacing an existing slab still requires geotechnical confirmation rather than assuming the old foundation's condition applies to new construction. The building envelope on either lot type follows the same coastal-rated standard used across this part of the county. Elements we specify on nearly every Lantana new build include:
- Elevation certificate and base flood elevation documentation on island lots
- Geotechnical evaluation confirming foundation type before design is finalized
- Impact-rated glazing package meeting wind-borne debris region requirements
- Corrosion-resistant hardware and flashing on any waterfront-facing structure
- Roofing rated for sustained coastal wind exposure
Sequencing From Site to Certificate of Occupancy
Construction proceeds through site work and any demolition, foundation and structural shell, envelope enclosure, then interior architecture and finish, with each phase gated by inspection before the next begins. On the island, elevation-related foundation work adds time to the early phases that an inland project doesn't encounter, since raised construction methods take longer than a standard slab.
Final inspections and certificate of occupancy require structural, mechanical, electrical and life-safety systems to each pass independently before the town signs off, and we track that sequence closely in the closing months of the build, since a single failed inspection can hold up final approval for the whole property.
What Drives the Cost of Building New
On the island, foundation and elevation strategy is the leading cost variable, since building above base flood elevation changes structural requirements and construction method compared to a standard slab-on-grade approach. Geotechnical findings can shift that budget further depending on soil conditions specific to the lot and its proximity to the water.
Inland, demolition and site preparation add cost before new construction starts, and lot size constraints mean the buildable footprint — and therefore the overall project scale — is often set by the site itself rather than by program ambition. Envelope specification adds a consistent cost layer on either lot type across town. Categories that shape a Lantana new-construction budget most include:
- Foundation type, including raised construction on island lots
- Demolition and site preparation where an existing structure comes down
- Geotechnical evaluation and any soil-related foundation adjustment
- Impact-glazing package sized to the final elevations
- Interior architecture and finish carpentry scaled to final square footage
Staying Informed Through the Build
A custom home runs long enough that structured updates at defined milestones — foundation complete, shell dried in, systems rough-in — give a clearer picture of progress than occasional informal visits, particularly on an island project where elevation work extends the early schedule beyond what an inland build would need.
We also coordinate delivery hours and staging with an awareness of neighboring properties on both the island and inland lots, since Lantana's smaller parcels put construction activity closer to adjacent homes than a larger estate lot would allow for over the course of the build.
Starting a Custom Home Project in Lantana
We begin with a site evaluation covering zoning and setbacks inland, or flood elevation and geotechnical conditions on the island, since those findings determine what an architect can reasonably design before a single drawing is produced for either lot type found in town, island or inland.
From there we coordinate with the architect and engineering team through design development, carry the project through Lantana's permitting process, and manage construction through foundation, shell, envelope and finish to final certificate of occupancy as one accountable team throughout the entire build, start to close.
Common questions
Yes. New construction resets the compliance clock regardless of what stood there before, so the lowest floor typically has to sit above base flood elevation as documented by an elevation certificate submitted with the permit package.
It depends on setbacks and lot coverage under the original subdivision's zoning. We confirm buildable footprint early in site evaluation so the design reflects what the lot can actually accommodate before drawings are finalized.
Island lots typically require elevating the lowest floor above base flood elevation, which affects structural method and space use below that elevation. Inland lots follow a more conventional slab foundation confirmed by geotechnical evaluation.
It depends on lot conditions, scope and how permitting review proceeds, especially where island elevation requirements extend the early schedule; we don't quote a fixed timeline until site evaluation and design are far enough along.
We coordinate delivery hours and staging with an awareness of adjacent properties, which matters more here than on a larger estate lot since Lantana's parcels put construction activity closer to neighboring homes.
