Luxury is not a finish — it is a feeling of permanence, privacy, and effortless comfort the moment you step inside. For coastal estates, that experience begins with the structure itself. Insulated Concrete Form (ICF) construction creates a level of silence, solidity, and livable comfort that conventional methods simply cannot replicate.
Where wood-frame homes flex, transmit sound, and age over time, an ICF estate feels grounded, composed, and architecturally substantial — the difference is not cosmetic, it’s experiential. The walls do not simply protect the home; they define the way it lives.
This structural integrity is why ICF has become the preferred standard for boutique coastal residences — not as an “upgrade,” but as the core element that separates a luxury property from a conventional one. For high-net-worth owners, ICF is not a material choice — it is a long-term investment in the quality, comfort, and legacy of the home itself.
Discretion. Permanence. A quieter, healthier, and more secure home. These are the motivations behind ICF in the luxury market — not marketing buzzwords.
Estate buyers in Palm Beach, Jupiter Island, Manalapan, and other shielded enclaves choose ICF because it aligns with how they think about property: as a generational asset, not a project.
ICF estates deliver:
For clients who expect not just beauty, but enduring value, ICF is the quiet standard of excellence.
True luxury architecture does not begin on paper — it begins with the confidence of a structure designed to endure. The most successful custom estates are not drawn toward a building method; they are designed around it.
ICF gives architects a foundation of permanence to create freely — wide-span openings, dramatic glazing, soaring interior volumes, and quiet sanctuary-like interiors become structurally appropriate, not aspirational.
Before a single line is drafted, we lead a pre-construction process that clarifies feasibility, massing, site orientation, prevailing winds, privacy lines, view corridors, and resiliency strategy. The result is not just a design — it is a correctly engineered vision, protected from downstream compromise.
This is where conventional builders diverge from estate-caliber development:
They “value engineer” after the design is complete. We safeguard the design before it is ever drawn.
For the high-net-worth client, this distinction is everything. It protects timeline, cost structure, architectural intent, and long-term livability — the hallmarks of a legacy estate.
Design-build at the luxury level is not about efficiency — it is about alignment. When structural logic and architectural ambition develop in parallel, the home becomes quieter, stronger, more refined, and more beautiful in its proportions.
We do not “fit construction to architecture”; we evolve both together. This is why our ICF estates feel cohesive down to the smallest detail — the walls, openings, transitions, and mechanical infrastructure are coordinated from inception, not improvised in the field.
Working directly alongside architects, structural engineers, and site planners, we remove friction, guesswork, and redesign cycles — replacing them with stewardship, precision, and clarity of intent.
Luxury is experienced first through atmosphere — the stillness of a room, the absence of outside intrusion, the sense of grounded calm as soon as you enter. ICF estates deliver a level of comfort that cannot be approximated by conventional framing:
It is not simply a quieter home — it is a more composed home. That composure is the heart of high-end livability.
In coastal Florida, true luxury is inseparable from security. A home built to outlast severe weather is not merely fortified — it is reassuring. This is why wealth preservation and ICF go hand in hand: the structure protects both the family and the asset.
ICF estates are engineered for category-level events, outperforming conventional methods in impact resistance, wind load, thermal performance, and fire protection. But more importantly, they remove uncertainty. The home is not just designed to “survive” — it is designed to remain intact, undisturbed, and timeless.
Permanence is the ultimate luxury.
In luxury estates, technology is successful when it disappears. The objective is not automation for its own sake — it is orchestration: security, lighting, climate, and infrastructure operating in harmony, quietly in the background.
ICF enhances this integration, not just by concealing and protecting infrastructure within the envelope, but by stabilizing the environment around it. The result is not a “smart home” in the consumer sense — it is a well-composed estate, where convenience and comfort are embedded in the structure rather than layered on top.
An ICF home is not simply “built differently” — it is conceived differently. At the estate level, structure, architecture, comfort, privacy, and longevity are developed together as a single experience. The result is a residence that feels intentional, substantial, and future-proof from the first day of occupancy.A luxury ICF estate with Rheace includes:
We offer two pathways into an ICF estate — both designed for clients who value permanence, privacy, and architectural intention.
For landowners or those redeveloping an existing property, we craft bespoke estates from the ground up — quietly, privately, and with full design-build alignment. Every detail is tailored to the way the family lives, entertains, and protects its long-term legacy.
In select locations, Rheace develops a small number of private, invitation-only spec estates — not mass-market builds, and never listed as retail product. These residences are curated in advance, designed as finished architectural statements, and acquired by clients who prefer a turn-key estate without entering a full design cycle.
Each spec residence is treated with the same stewardship as a commissioned custom home — the difference is only in timing, not intention.
Luxury is not “custom or spec.”
Luxury is curated or commissioned.
The strength of an ICF residence is most appreciated in markets where architecture, privacy, and permanence are not preferences — they are requirements. Our work is focused exclusively in the coastal and estate enclaves where structural integrity and long-term asset preservation matter most.

ICF (Insulated Concrete Form) homes are built using interlocking foam blocks that are stacked to form the exterior walls, then filled with reinforced concrete. At Rheace Contracting, we utilize Nudura ICF systems, which create walls that are significantly stronger than traditional wood-frame construction. The Nudura ICF blocks consist of two layers of expanded polystyrene (EPS) foam insulation with concrete poured between them, resulting in walls that are typically 6-12 inches thick. This construction method provides superior structural integrity, insulation performance, and protection against hurricanes, fire, and extreme weather conditions common in South Florida.
Nudura ICF construction offers multiple advantages over traditional wood-frame building, especially in Florida's challenging climate. ICF walls provide Category 5 hurricane protection with wind resistance up to 250 mph, compared to standard construction which typically fails at much lower wind speeds. Fire safety is dramatically improved, with Nudura ICF walls offering 4+ hours of fire protection versus just 45 minutes for wood-frame homes. Additionally, the superior insulation properties of Nudura ICF reduce energy costs by 40-60%, maintain consistent indoor temperatures year-round, and provide exceptional soundproofing. The concrete core also prevents moisture infiltration, termite damage, and mold growth—critical factors in South Florida's humid coastal environment.
Building a luxury ICF home with Nudura systems typically costs 5-10% more than traditional construction initially, but this is offset by long-term savings and value. The investment includes higher upfront material and specialized labor costs, but homeowners save 40-60% on energy bills, benefit from lower insurance premiums due to superior hurricane and fire resistance, and enjoy minimal maintenance costs over the home's lifetime. For custom luxury homes in Palm Beach and Martin Counties, clients can expect the added ICF investment to pay for itself within 5-7 years through energy savings and insurance reductions alone. Most importantly, Nudura ICF construction significantly increases property value and marketability, making it a sound long-term investment.
Custom ICF homes built by Rheace Contracting typically require 12-18 months from initial design to completion, because homes of this caliber cannot be rushed. Each phase receives the time, attention, and craftsmanship that generational architecture demands. The Nudura ICF wall installation itself is efficient—often completed in just a few weeks—but the overall process includes architectural design, engineering for South Florida's coastal conditions, permitting, foundation work, ICF wall construction, interior finishing with premium materials, and final inspections. For clients seeking a faster move-in option, our luxury spec homes offer turnkey Nudura ICF construction without the extended custom design timeline, typically available within 6-9 months.
Yes, Nudura ICF homes provide exceptional hurricane protection that far exceeds traditional construction standards. ICF walls can withstand winds up to 250 mph—well beyond Category 5 hurricane strength—and prevent wind-blown debris from penetrating the home's exterior. In South Florida, where hurricanes are an inevitable reality, this level of protection is critical. Nudura ICF construction doesn't just meet Miami-Dade hurricane codes; it dramatically exceeds them, providing structural integrity that remains intact during extreme weather events. The monolithic concrete core, combined with impact-rated windows and standing seam metal roofing, creates a complete building envelope that keeps your family safe and your home secure when storms strike. This superior protection also translates to lower insurance premiums and peace of mind that your luxury investment will endure for generations.
