Outdoor Kitchens, Sunrooms, Decks and Screened Porches on Hilton Head Island

Outdoor living costs on Hilton Head depend on which project you build and how large it is. Screened porches run $90 to $185 per square foot, decks run $75 to $125 per square foot, outdoor kitchens run $100 to $500 per linear foot of counter run, and sunrooms or four-season rooms run $150 to $325 per square foot. Within each, the finishes, materials and utility work chosen move the number. Design and construction happen under one roof, with a design agreement first and a fixed-price construction contract after, so the number you agree to is the number you pay. A project walkthrough gives you a range specific to your home.

A screened porch on Hilton Head typically runs $90 to $185 per square foot. A 320 sq ft screened porch typically costs $29K to $59K. The final number depends on a few things: the roof structure and whether it ties into the existing roofline, whether the porch sits on a new slab, piers, or an existing deck, the flooring and ceiling finishes chosen, and the screen system, lighting and fans added. Design and construction are handled under one roof, with a fixed-price construction contract after design, so the number you agree to is the number you pay. For a range specific to your home, a project walkthrough is the next step.

An outdoor kitchen on Hilton Head typically runs $100 to $500 per linear foot of counter run, so a 30 lin ft outdoor kitchen typically runs $3K to $15K. That price is priced per linear foot of counter run and covers the cabinetry, countertop, appliances and the utilities behind them. The number moves with the appliances and countertop material chosen, the length of the run, and how far gas, water and electric have to be brought to the kitchen. The patio or deck the kitchen sits on is priced separately, per square foot, under decks, so one slab is never priced twice. For a number specific to your home, a project walkthrough and room-by-room range is the next step.

A sunroom or four-season room on Hilton Head typically runs $150 to $325 per square foot. A 300 sq ft sunroom typically runs $45K to $98K. Design and construction are handled under one roof, with a design agreement first and a fixed-price construction contract after, so the number you agree to is the number you pay. For an estimate specific to your home, a project walkthrough and room-by-room range is the next step.

A deck on Hilton Head typically runs $75 to $125 per square foot. A 600 sq ft deck typically runs $45K to $75K. The number moves with the decking and railing materials chosen, whether composite, cable or metal, the height of the deck above grade, which sets the foundation and inspection requirements, and the amount of stairs, railing and built-in features. The foundation type matters too, since footing, rebar, concrete, anchor bolt, masonry or piling work each call for their own inspections. For a number specific to your home, a project walkthrough and room-by-room range is the next step.

Outdoor structures on Hilton Head Island are permitted through the Town of Hilton Head Island, except in Windmill Harbour, which is permitted by Beaufort County. If the project sits in a plantation, or in some areas outside one, it needs ARB approval before a permit application can even be submitted: the ARB reviews a concept and issues an approval letter, and the Town will not accept the permit without it. HHI Builders handles the permit pull. Turnaround runs from as little as two days for a simple freshen-up to one to five weeks for most projects, and up to five weeks for structural work that needs engineering and plan review.

The materials that hold up best on Hilton Head are composites, pressure-treated framing, metal or cable railings, cement-board siding and trim, and windows clad in metal or fiberglass, or vinyl. Composite decking and trim resist rot in the coastal humidity, pressure-treated framing stands up to moisture underneath, and metal or cable railings shrug off salt air without the upkeep that bare wood needs. Cement-board siding and trim hold paint and shape better than wood siding over time. HHI Builders specifies these materials on outdoor kitchens, decks, screened porches and sunrooms for that reason. Any outdoor structure also needs ARB approval before work starts, and the foundation type (footing, pier, piling, or slab) determines which inspections apply.
