Project Overview & Homeowner Objectives in Grove City & Pine Township

Homeowners across Highland Avenue, Edgewood Avenue, and the spacious properties of Pine and Liberty Townships in Grove City, PA love hosting family gatherings outdoors—from Grove City College homecoming weekends to summer cookouts—yet sudden afternoon thunderstorms and blazing midday sun can quickly drive guests back indoors. For this backyard resort upgrade, our clients wanted a free-standing 16×24-foot heavy-timber cathedral pavilion anchored over their patio, complete with a standing-seam metal roof, a mounted outdoor television, ceiling fan, dimmable timber lighting, and a natural gas fire table—all without a single ugly metal electrical pipe visible on the wood posts.

Property Profile & Pre-Renovation Challenges

Lightweight big-box aluminum or thin cedar pergola kits buckle under Mercer County’s heavy lake-effect snow bands and uplift during severe summer squalls. Building a true architectural pavilion requires deep reinforced concrete piers, heavy-timber structural joinery, and pre-routed concealed mechanical utilities.

Scope of Work & Turnkey Single-Team Coordination

• Excavation and pouring of four 42-inch deep frost-line concrete piers integrated into the stamped concrete patio.
• Design and erection of a custom heavy-timber pavilion with arched knee braces and a 24-gauge standing-seam metal roof.
• In-house licensed electrical concealed timber wiring and plumbing underground natural gas piping.

Heavy-Timber Structural Joinery, Lake-Effect Snow Engineering & Standing-Seam Roofing

42-Inch Frost Piers & Concealed Steel Knife-Plate Anchors

To support the dead weight of heavy timber rafters and a 40-PSF Mercer County snow load while resisting 115-MPH wind uplift, we excavated four 20-inch diameter piers down 42 inches below grade and poured 4,500 PSI concrete reinforced with rebar cages. Rather than using ugly galvanized surface brackets, we embedded Simpson Strong-Tie concealed knife-plate post bases that hold the 8×8 kiln-dried Douglas Fir columns 1 inch above the concrete pad—preventing end-grain water wicking and securing the columns with through-bolted structural dowels.

Arched Knee Braces, Tongue-and-Groove Decking & Standing-Seam Metal Roof

Our carpenters framed the open cathedral span using 6×12 heavy-timber carrier beams, curved mortise-and-tenon knee braces reinforced with architectural black powder-coated steel gusset plates, and 2×8 V-groove tongue-and-groove ceiling decking stained in a UV-stable translucent cedar tone. Above the wood deck, we applied high-temperature ice-and-water shield and mechanically seamed a 24-gauge Kynar 500 Matte Black standing-seam metal roof with concealed fasteners that will last 50+ years without a single exposed washer screw.

Concealed In-House Electrical & Underground Gas Integration

Routing Power Inside the Timbers Before Assembly

When an electrician shows up *after* a pavilion is built, they have no choice but to strap silver metal conduit pipes up the outside of your stained wood posts. Because Dependable Home Solutions employs in-house licensed electricians and carpenters working side by side, we routed recessed wire channels directly into the back of the 8×8 posts and ridge beam before lifting them into place, concealing them behind flush-fitted wood spline caps. We trenched a 30-amp underground feeder to power a 60-inch wet-rated fan, four dimmable timber LED downlights, weather-resistant GFCI outlets, and a weatherproof TV enclosure on the gable end, while our plumbers stubbed up a natural gas quick-connect right in the center of the seating area.
