The True Cost of a Luxury Custom Driveway Gate in Northern California

When we quote a custom driveway gate, we break it into five core components. Understanding each one helps you scope your budget with clarity instead of sticker shock.

Hardwood and materials account for 25–35% of the total, driven by species, board feet, grain matching, and thickness. Automation and operator come in at 20–30%, sized to gate weight, cycle frequency, and smart-access integration. Ironwork and hardware represent 15–25%, with the spread between forged and cast, ornamental versus minimal, and the engineering of the hinge system. Finish and protection — marine-grade sealers, UV-stable stains, and maintenance plans — account for 10–15%. Design, fabrication, and installation make up the final 15–20%, covering CNC complexity, site conditions, and electrical trenching.

The hardwood you choose sets the baseline. For a typical 14-foot dual-leaf estate gate (180–220 board feet), here's how the species we work with most often stack up:

Sapele — $4,500–$7,500. Our signature wood. Mahogany-like, stable, beautiful ribbon grain. Sustainably sourced. Excellent for Bay Area marine climates.

White oak — $5,500–$9,000. Dense, strong, takes stain beautifully. Heavier than Sapele, which affects hardware and operator sizing.

Ipe — $7,000–$11,000. Ultra-durable, naturally resistant to rot and insects. Dense and hard on tools, but lasts 40+ years with minimal maintenance.

Teak — $10,000–$16,000. The gold standard. Naturally oily, virtually impervious to water. Premium pricing reflects global demand and sustainable harvesting constraints.

Sapele offers 85% of Teak's weather resistance at roughly 40% of the material cost. That's why it's our default recommendation for Bay Area estates. But if you're building a gate for a coastal Marin property with salt air and no overhang, Teak or Ipe earns its premium.

A luxury gate isn't just beautiful wood. It's a machine that opens and closes reliably, rain or shine, thousands of times a year. For estates in Atherton, Hillsborough, and Woodside, we typically specify heavy-duty linear or articulated arm operators rated for 1,500+ lbs per leaf, photoelectric and edge safety sensors on both leaves, loop detectors for vehicle presence, smart access control (keypad, remote, app-based, or integrated with Control4, Lutron, Ring, or Apple Home), and battery backup for power outages.

Operator packages typically run $6,000–$18,000 depending on gate weight, cycle speed requirements, and integration complexity. A dual-leaf 16-foot white oak gate with smart-home integration and battery backup lands squarely in the middle of that range.

Wrought iron should complement the hardwood, not compete with it. We collaborate with Bay Area blacksmiths on hinge straps and pintles engineered for gate weight, ornamental scrollwork, spears, and custom motifs, frame reinforcement for wide-span gates, and automated latching mechanisms.

Ironwork ranges from $3,500 for clean, minimal hardware to $15,000+ for elaborate forged panels and custom motifs. The key is proportion. A heavy iron frame on a delicate Sapele leaf looks institutional. A whisper-thin iron accent on a massive Teak gate looks temporary. Balance is everything — for more on hardware specifically, see our piece on hand-forged iron hardware.

Bay Area sun, fog, and occasional hard rain are tough on exterior wood. Our standard finish protocol is a penetrating oil or marine-grade sealer (Sikkens, Penofin, or custom-mixed), a UV-stable pigmented topcoat to prevent graying, and an annual inspection and touch-up plan included for two years, then optional.

Finish and initial protection runs $2,500–$5,000 depending on gate size and complexity. Ongoing maintenance budgets $800–$1,500 annually for inspection, hardware lubrication, finish touch-ups, and operator calibration. A well-maintained Sapele gate will look stunning at year 15. A neglected one will show it by year 5.

Atherton estate — Sapele swing gate — $34,000. 14-foot dual-leaf swing, Sapele at 2.25" thick with bookmatched panels, minimal forged hinges and latch in black powder coat, linear operator with keypad and remote, marine-grade sealer in satin. The homeowner wanted warmth and understatement. The Sapele's ribbon grain does the talking. Clean lines, no scrollwork, just precision joinery and hardware that disappears.

Hillsborough property — white oak and iron statement — $62,000. 18-foot dual-leaf swing, white oak at 2.5" thick with a custom CNC-engraved family crest, forged scrollwork top rail and heavy-duty strap hinges with automated latch, articulated arm operator with smart-home integration, battery backup, and loop detector, custom stain to match the front door with UV topcoat. This gate needed to carry visual weight. The white oak's density justified the heavier ironwork, and the CNC-engraved crest turned a functional entry into a family heirloom.

Woodside compound — Teak and wrought iron estate gate — $118,000. 24-foot dual-leaf swing with custom pier columns, Teak at 3" thick with matched grain across both leaves, full forged frame with ornamental spears, custom motif, and integrated lighting, dual linear operators with app control, video intercom, solar backup, and full safety suite, natural oil finish with an annual maintenance plan prepaid five years. The Teak will outlive the house. The ironwork was designed to patina gracefully. Every component was oversized for reliability. This is a gate that will still be opening smoothly in 2040.

Measure your opening — width, height, slope, clearance. Choose your hardwood — Sapele for value, Teak or Ipe for extreme exposure. Decide on automation — manual, basic operator, or full smart integration. Define your ironwork — minimal, functional, or ornamental statement. Factor in site work — electrical trenching, pier columns, landscaping. Plan for maintenance — annual care protects your investment.

Every estate we build for starts with a site visit and a conversation about architecture, landscape, and how the gate will be used. From there we sketch, render in CAD, and walk the client through the full quote with every line item exposed.
