Custom Backyard Additions in Columbus, Ohio

A backyard addition should look and work like it was planned with the home, not dropped into the yard afterward. PrimeBuild Designs creates custom pool houses, cabanas, covered bars, and entertainment pavilions across Central Ohio, coordinating the structure, utilities, finishes, and surrounding outdoor spaces as one complete project.

The scope

What we build

  • Custom pool houses and pool cabanas
  • Changing suites, bathrooms, and integrated storage
  • Covered outdoor bars and entertainment pavilions
  • Open-air and enclosed backyard structures
  • Kitchens, lighting, power, plumbing, and finished interiors
  • Structures integrated with patios, pools, outdoor kitchens, and fire features

The investment

What drives the cost

Backyard additions can range from an open pavilion to a fully finished pool house, so the scope inside the structure matters as much as its footprint. The main cost drivers are:

  • Structure size, roof design, foundation, and finish level
  • Open-air construction versus conditioned or enclosed space
  • Bathrooms, showers, kitchens, bars, and built-in storage
  • Electrical, lighting, plumbing, gas, and utility-run distances
  • Masonry, siding, trim, ceilings, doors, windows, and interior finishes
  • Patios, steps, drainage, and connections to the surrounding backyard
  • Engineering, permitting, site access, and municipality requirements

01

Typical timeline

The full schedule includes design, selections, structural planning, utility coordination, municipal review, and construction. Open pavilions are typically simpler than finished buildings with plumbing and interior rooms. We establish the dependable sequence after the site and scope are confirmed, and early planning gives the best chance of having the space ready for the season you want to use it.

02

Materials

Rooflines, siding, masonry, trim, columns, ceilings, doors, and windows are selected around the main house rather than from a one-style package. Every exterior assembly is planned for Central Ohio weather, while interior and utility specifications follow how the building will actually be used.

03

Permits and inspections

Most permanent backyard structures require zoning or building review, and bathrooms, kitchens, electrical work, gas, and utility connections add their own inspections. Setbacks, lot coverage, foundation requirements, and utility paths vary by municipality. We identify the applicable path before the construction schedule is locked.

Straight answers

Backyard addition planning questions

Use, utilities, architecture, and the surrounding backyard should be settled before the structure is designed in detail.

What counts as a backyard addition?

On this page, a backyard addition means a permanent outdoor structure such as a pool house, cabana, covered bar, or entertainment pavilion. It does not mean an enclosed room addition to the main house.

What is the difference between a pool house, cabana, and pavilion?

A pool house is often enclosed and may include utilities, changing rooms, storage, or a bathroom. A cabana is commonly smaller or more open to the pool, while a pavilion is primarily a roofed entertainment space. The right form follows how you want to use the backyard.

Can the structure match my house?

Yes. We coordinate rooflines, proportions, materials, trim, masonry, and colors with the home, then use project visuals to make the relationship clear before construction.

Can a backyard addition include a bathroom, kitchen, or bar?

Yes. Bathrooms, changing suites, kitchens, covered bars, power, lighting, and storage can be planned into the structure. Those features affect utilities, permits, budget, and timeline, so they need to be scoped early.

Will my backyard addition need a permit?

Most permanent structures need some combination of zoning, building, electrical, plumbing, or gas review. The exact requirements depend on the municipality, placement, size, utilities, and whether the structure is open or enclosed.
