ICF Homes in Sarasota, Florida
Sarasota builds some of the finest custom homes on the Gulf Coast. We build the version that also stands up to the Gulf.
Sarasota's custom-home market is one of the most sophisticated in Florida — architect-driven houses on Siesta Key, Lido, Longboat, and along the bayfront, plus a steady run of high-end mainland builds east of the Trail. It's also a market that has been reminded, storm after recent storm, that the Gulf sets the terms. Ian passed close enough in 2022 to rattle the whole county, and the 2024 season put surge into barrier-island streets that had stayed dry for generations.
Net Zero Homes LLC brings insulated concrete form construction to Sarasota's custom and coastal projects: a solid reinforced concrete core with 5+ inches of continuous EPS insulation, engineered to resist hurricane-force winds and flying debris. Stucco, stone veneer, siding, and brick all attach to ICF, so the modern coastal architecture Sarasota is known for doesn't change — only what's behind it does.
We build under Florida contractor license CBC1253609, held since 1999 and ICF-exclusive since 2003, working alongside architects and custom builders rather than around them.
Barrier-island stakes
Homes on Siesta Key, Lido Key, and Longboat Key carry both the highest values and the highest exposure in the county. ICF walls on elevated foundations address wind and surge in the structure itself, not just in the shutters.
Architecture without compromise
Sarasota's design tradition favors clean modern lines, deep overhangs, and glass. ICF supports all of it — the wall system disappears behind stucco or cladding while adding concrete strength and STC 50+ quiet.
A luxury market that values resilience
Sarasota buyers increasingly ask about survivability before finishes. A concrete home with a FORTIFIED designation may qualify for meaningfully lower wind premiums — substantial savings on the wind portion.
Retiree and relocation demand
Much of Sarasota's new construction is for buyers arriving from out of state who plan to stay for decades. ICF suits that horizon: no rot, nothing for termites to eat, and cooling bills commonly 30–50% lower than frame.
Why Sarasota homeowners choose ICF
The pattern in Sarasota is consistent: buyers who watched neighbors repair frame houses after recent storms want the next house to be the last one they worry about. ICF delivers that without asking them to live in a bunker. The concrete core provides the wind and debris resistance; the continuous EPS insulation provides the comfort; the mass provides quiet that matters on a busy key or near downtown.
It also fits how Sarasota builds — custom, engineered, architect-led. We support design teams from schematic stage through the pour, including architectural support for ICF projects and consultation and design support for owners still choosing an approach.

ICF in Sarasota: FAQs
Can you build ICF on Siesta Key, Lido Key, or Longboat Key?
Yes. The keys are mapped flood zones with elevation requirements, and ICF pairs well with elevated foundations. The concrete walls resist wind, debris, salt air, and moisture intrusion — the exact conditions barrier-island homes face.
Will ICF limit the architectural style of a Sarasota custom home?
No. Stucco, siding, stone veneer, and brick all attach to ICF, and the system handles the clean modern forms Sarasota architecture favors. We regularly work directly with architects and offer ICF-specific design support.
How far is Sarasota from your Groveland headquarters?
Roughly two hours. Sarasota sits inside our Gulf Coast service area, which runs from Tarpon Springs south through Naples, and we schedule coastal projects there as a normal part of our rotation.
Does Sarasota County permitting accept ICF construction?
Yes. ICF is an engineered reinforced-concrete wall system under the Florida Building Code, permitted on sealed plans like any concrete home. We provide the ICF details and support your design team through Sarasota County or City of Sarasota review.
