We at a Avant have the ability to make projects from conception to delivery. 

Avant Construction was founded in 1996 by Frinee Mattesich, a civil engineer and a 20-year veteran of the construction industry. In cooperation with a telecom company, Avant commenced operations as a builder of data centers and satellite earth stations. As a general contractor, the company evolved to build custom homes, commercial projects, and sundry projects on behalf of local governments in Charlotte and Lee Counties (South West Florida). As a subcontractor to other builders, Avant specializes in the structural elements of buildings to meet strict hurricane hardening codes for all concrete, masonry, and roofing components of a structure. Avant now offers the full range of design-build services for the residential, commercial and public sectormarkets, including repair, remodeling, and “greening” of new and existing buildings.
