TechFive designs and builds custom composite, wood, and hybrid decks for homeowners in Oshkosh and the Lake Winnebago area. When projects include covered decks, screened porches, or patio roof structures, we coordinate structural planning, load paths, and water management before construction begins.

Every build is planned around structural performance, material durability, and how the space will actually be used—ensuring long-term value in Northeast Wisconsin’s climate.

Oshkosh homeowners choose TechFive when they want a defined plan—not guesswork. We focus on custom deck construction, covered outdoor living spaces, and structural roof systems designed specifically for the home, layout, and site conditions.

From open-air decks to permanent patio roof structures, our work emphasizes proper framing, clean tie-ins, and structural clarity. Projects are designed first—then built—so the finished result fits the home instead of forcing the home to fit the project.

We work with Oshkosh homeowners on a focused range of deck and residential projects, each defined by clear scope, structural planning, and material standards before construction begins, including:

Every project we build in Oshkosh is designed around the home’s elevation, drainage patterns, structural conditions, and intended use of the space. Layout, materials, and connection details are defined before construction begins, ensuring the finished structure integrates cleanly and performs long term.

Most construction problems don’t start with poor workmanship—they start with unclear planning. Our design-build process helps Oshkosh homeowners make key decisions early, align expectations, and reduce mid-project adjustments. The result is a smoother build experience and a structure that performs as intended.

Outdoor structures in Oshkosh must account for freeze-thaw cycles, snow load, wind exposure, and seasonal moisture—especially near Lake Winnebago. Structural planning, drainage strategy, and material selection must reflect those conditions from the start.

Framing layouts based on elevation and wind exposure

In addition to Oshkosh, we work with homeowners throughout the surrounding Lake Winnebago and Fox Valley communities, including Winneconne, Omro, and nearby residential areas. We bring the same planning-first process and structural standards to every site we serve.

Every Oshkosh project begins with a focused review to evaluate layout, structure, materials, and feasibility. This allows us to determine alignment early and ensure your deck or outdoor living project is properly planned before construction begins.
