Built-In Benches & Planters
Built-in benches and planters is the Handis carpentry that turns a flat deck into a place people actually want to sit and a space that grows herbs six feet from the cook surface — L-shaped, U-shaped, or perimeter cedar benches integrated into the deck rail or anchored to the framing, plus matching cedar planters built into the rail or freestanding on the deck surface with proper drainage. Three to six working days per project, from $1,500 for a single 6-foot bench with hidden fasteners to $5,000 for a full L-shape with three integrated planters and matching back-rest. Cedar is the Pacific Northwest default — ages to silver patina that looks intentional in eighteen months, resists rot for fifteen to twenty years without a finish, and matches the typical deck board. Every seat surface gets hidden fasteners (Camo screws, Cortex plugs) so nothing snags shorts or seats. Every planter gets a perforated liner, a drainage gap, and stand-off blocks so soil does not sit on the deck and rot the boards underneath. The build is pure Handis carpentry — no plumber, no electrician, no permit. We measure, we build, we leave.
Service
How the Bench-and-Planter Build Works
Five sequential phases from layout to last fastener — the actual sequence we run on every built-in bench and planter project. No licensed-sub handoff; this is pure Handis carpentry.
Estimate Visit + Layout Confirmation + Cedar Order
On the estimate visit we confirm the bench shape (single straight, L-shape, U-shape, perimeter), the planter count and locations, the cedar grade (clear or knotty), the fastener system (Camo edge-screws or Cortex plugs), and the finish preference (silver patina or penetrating sealer). Cedar is ordered to length so we cut as little as possible on site. Clear-grade cedar lead time is typically three to seven working days from a Seattle lumberyard.
Frame Layout + Anchoring to Deck Framing
Pressure-treated 2x4 or 2x6 frame laid out on the deck per the agreed footprint, anchored to the deck framing (joists or beams) with hot-dip galvanized Simpson Strong-Tie angle brackets. The frame is set true, plumb, and level before any cedar goes on. Bench height locked at 17 to 18 inches; back-rest height locked at 14 to 16 inches above the seat. Day 1.
Cedar Seat + Back-Rest Install with Hidden Fasteners
Clear-grade cedar boards (typically 5/4 by 6 or 2 by 6) installed on the seat surface and the back-rest with the chosen hidden-fastener system. Camo edge-screws drive at an angle into the board edge so nothing shows on the seat. Cortex plugs cover face screws with matching cedar. Either way no fastener head telegraphs through the seat. Front edge of each seat board gets a 1/4-inch round-over with a router so the edge is comfortable against the back of the knees. Days 1 to 2.
Planter Box Construction with Drainage + Stand-Off
Cedar planter boxes built to the agreed size and location, with a 1/2-inch drainage gap between bottom boards, perforated landscape-fabric liner sized to the box, and cedar stand-off blocks 1/2 inch above the deck so water drains under the planter, not against the deck boards. Soil sits on the liner; you can change out plantings any season. Days 2 to 3.
Optional Finish + Walk-Through + Hand-Off
If you chose the silver-patina path the cedar gets installed raw and starts patinaing immediately. If you chose the penetrating sealer we apply one coat of Cabot Australian Timber Oil, Penofin, or TWP at install and walk you through homeowner re-application every two to three years. Walk-through with you, hand-off of warranty paperwork. Final fastener heads checked, edges round-overed, no splinters left on the seat.
Built-In Benches & Planters Pricing
Final pricing depends on bench length, bench shape (straight, L-shape, U-shape, perimeter), planter count, cedar grade (clear costs more than knotty), and finish (silver patina is no-cost; penetrating sealer add).

Why Homeowners Book Handis for Built-In Benches & Planters
A built-in cedar bench looks like a small, simple build until you sit on one that was done wrong. The seat that catches the back of the leg on a recessed screw divot every time you stand up. The planter set directly on the deck with no stand-off and the cedar board underneath turns black with rot in eighteen months. The back-rest pitched at 95 degrees so no one can lean back without their head hitting the rail. The fastener heads streaking rust down the seat board within twelve months because the contractor used plain galvanized screws instead of stainless. None of these are exotic mistakes — they are the production shortcuts that happen when the crew has never had to live with their own bench. Handis builds benches we would actually sit on, with hidden fasteners on every seat, proper drainage on every planter, comfortable back-rest pitch (95 to 100 degrees off vertical), and stainless hardware so the cedar ages without streak. Three to six working days, no permit, no licensed sub, no surprises.
Estimate
Tell us the deck (footprint, age, board material), the bench shape you have in mind (single straight, L-shape, U-shape, perimeter), the planter count and rough location preference, the cedar grade preference (clear or knotty), and the finish preference (silver patina or penetrating sealer). We send back a clear estimate and a project timeline.
Customer Reviews
Built-in benches and planters reviews from real Seattle-area Handis customers.
L-shaped cedar bench around two sides of our Bellevue deck with a matching back-rest and two integrated planters at the ends. Five working days. The hidden Camo fasteners are the detail that mattered most — my kids sit on it daily and no one has caught a knee on a screw head. The planters have a perforated liner and stand-off blocks, and the rosemary has been alive through fourteen months including last December's freeze.
Single 6-foot cedar bench with back-rest along the back rail of our Magnolia deck. Three working days. Clear-grade cedar, all stainless hardware, no finish — they recommended letting it patina and after eighteen months the bench is a soft silver that looks intentional. The back-rest pitch is comfortable for actually reading on. Cost $2,100 with the back-rest add-on. Worth every dollar.
Full U-shape perimeter bench around our Issaquah deck with three integrated planters and matching back-rest on all three sides. Six working days as quoted. The crew worked clean — drop cloths down every day, fasteners and offcuts swept up at the end of each day, no splinters left on the seat. The bench has been the gathering point for every family dinner since.
We had a previous contractor build a similar bench five years ago that streaked rust within eighteen months because he used plain galvanized screws. Handis pulled the old bench (which we asked them to dispose of), framed a new one with full stainless hardware and hidden Camo screws, and matched the original L-shape. Five working days. Two years in, zero rust streak, no maintenance needed. The difference is real.
Three standalone cedar planters on our existing deck — 24-inch boxes, perforated drainage liner, stand-off blocks so the deck stays dry underneath. They mocked up the placement with painter's tape before they committed so we could see where they actually wanted to put them. Single day of work. We have herbs and a Japanese maple in them now and the cedar is patinaing exactly as they described.
