What is Design+Build?

The Design+Build process means one entity orchestrates both design and construction to produce maximum results from a fully coordinated, collaborative team throughout the entire process. Design leads in creating the concept and construction informs design, producing a cost-effective, imaginative, unique and fully constructable home with the highest levels of quality and craftsmanship in a highly efficient manner.


All of our homes are designed and built with Gold Standard Specifications using what we believe to be the best possible materials and sustainable building practices.

Our Approach

At Vertical | Design+Build, we have more than 50 years of experience in designing and building award-winning, high-end custom homes along Florida’s beautiful Gulf Coast.

Unlike traditional custom home builders, Vertical | Design+Build features an internal design studio headed by a state licensed architect and a team of interior designers, along with a construction management staff who work together in a fully coordinated process to deliver extraordinary experiences in the design and quality construction of your new home.

When it comes to designing and building your home, our approach allows Vertical | Design+Build to provide a best in class level of operational and project excellence.
