About Us

Raising the Standard for Building in Coastal Florida

Net Zero Construction is a Sarasota-based custom home builder focused on one thing: building homes that perform when it matters most. Using advanced materials, ICF construction, hurricane-resistant methods, and energy-efficient design, we create luxury homes that protect your family and preserve long-term value on Florida’s Gulf Coast. Learn about our net-zero home builder approach.

The Net Zero Difference

What You See. What Protects It.

A finished custom home is only part of the story. Net Zero coordinates the walls, floors, roof, openings, structural connections, and building envelope around the design, site, and demands of Florida's coastal environment.

01

ICF Reinforced Concrete Walls

Insulated Concrete Form walls combine a reinforced concrete structural core with continuous insulation, supporting structural resilience and thermal performance.

02

Concrete Floor & Roof Systems

Reinforced-concrete or InsulDeck floor and roof assemblies may be used where the design and engineering call for them, rather than applying one system everywhere.

03

Impact-Rated Windows & Doors

Impact-rated openings help maintain the integrity of the building envelope while supporting protection against demanding Gulf Coast weather conditions.

04

Hurricane-Resilient Structural Design

Walls, floors, roof systems, openings, and structural connections are coordinated around site-specific loads and the demanding wind conditions of Florida’s Gulf Coast.

05

High-Performance Building Envelope

Continuous insulation, air sealing, roofing, flashing, and moisture-control details work together to support comfort, durability, and energy performance.

06

Built for Coastal Florida

Net Zero brings more than 25 years of hands-on experience to homes exposed to Florida heat, humidity, wind, heavy rain, and coastal conditions.

Luxury is not only what you see. It is how the structure, envelope, and systems behind the finishes work together.

Our Process

A Coordinated Approach to Building on Florida’s Gulf Coast

Building a custom home in Tampa Bay or the broader Florida Gulf Coast region requires careful coordination between design, engineering, materials, and construction. Our process keeps homeowners informed while bringing architects, engineers, trades, structural systems, and building-envelope details together from planning through completion. Read our hurricane-resistant construction guide and our HERS rating guide for more context.

01

Establish the Project

We begin by understanding your property, goals, priorities, and budget. Site conditions, coastal exposure, structural needs, energy performance, and overall feasibility are considered early so the project starts with a clear direction.

02

Build the Right Team

We get involved early to understand the property, project goals, feasibility, and budget. If your design team is not already in place, we help connect you with the right architect, design professionals, and engineers, then coordinate closely with that team as the plans develop and construction moves forward.

03

Verify Every Stage

Throughout construction, critical details are reviewed and documented as the home takes shape. Structural connections, waterproofing, flashing, openings, insulation, and other performance-related details receive attention before they are covered by finished materials.
