Gun-metal patina, elevated: How a client vision became a defining detail.

A single YouTube clip inspired a month-long transformation, turning raw structural steel into a seamless gun-metal patina that defines this oceanfront home’s industrial elegance.

A Vision Sparked by a Pocket Knife with a Distinct Patina

When the owners of our Oceanfront Industrial Farmhouse arrived with a short YouTube clip of a pocket-knife blade, they weren’t sharing a novelty – they were sharing a vision. The blade’s rich gun-metal patina was equal parts rugged and refined, and they asked if that exact character could flow across every structural steel element already standing in their nearly finished waterfront home. That single question launched one of the most complex, collaborative, and rewarding chapters in our thirty-plus years of crafting one-of-a-kind residences.

At the time, every exposed beam and bracket – vaulted ridge beams 30 feet above the great room, a cantilevered bridge walkway nearly 40 feet long, a sculptural staircase, and a 4,000-pound built-in bookcase – sat in factory primer awaiting a simple top-coat. A coat of paint would have been quick and predictable; it also would have fallen short of the client’s imagination and our own standards. Instead, our team sourced a reactive blackening chemistry from a specialist in California whose formula delivered the depth, warmth, and subtlety the owners loved.

Testing Before Commitment

Before committing the entire home to a new path, we slipped into laboratory mode. Sample coupons – bolts, plate-steel off-cuts, and welded seams – were blasted back to bare white metal and treated under controlled conditions. We trialled several blast media before crushed glass revealed itself as the perfect balance of gentle profile and stripping power, even if it was the slowest to use. Only when every sample showed consistent colour and adhesion did the owners approve the full treatment, and our construction calendar pivoted to accommodate a month-long micro-project inside the larger build.

Testing, testing, testing. This is one of the samples prepared for our clients prior to committing to the patina finish throughout.

Preparing for Precision Work

Protecting a sealed, high-performance house from two tonnes of airborne glass demanded meticulous planning. Windows and sliders were wrapped in plywood and poly, every duct and electrical opening was sealed, and adjacent finishes – from polished concrete floors to drywalled surfaces – were thoroughly masked. A mobile blast crew spent a week erasing primer and mill scale from every millimetre of steel.

A specialty mobile media blasting contractor was brought in from Vancouver to assist with preparation of the steel elements prior to applying the patina finish.
Not for the faint of heart – shooting over 2000 pounds of crushed glass into a partially finished house requires immense preparation. Here the blasting contractor is removing mill scale from the elevated bridge walkway structure inside the front entry of the home.

When the dust cleared, raw silver beams glimmered in coastal light – and the race against surface corrosion began.

Battling the Coastal Climate

Salt-laden air has no mercy on naked steel, so we brought in industrial electric heaters and commercial dehumidifiers to hold the interior environment steady while finishing proceeded. Working from floor level to ridge in tightly choreographed passes, our coating contractor misted on the patina solution, let the chemical reaction bloom, neutralised, and repeated until the steel settled into a unified charcoal tone. Flash rust appeared – an expected part of the process – and was carefully buffed away before two protective coats of clear coat locked in the finish without muting its natural variation.

It takes a team – our coatings contractor worked as a team of 4-5 individuals to ensure a perfect finish.

A Finish That Feels Original

The result is a seamless gun-metal patina that ties together welds, bolts, beams, and balustrades so convincingly you would swear the steel left the mill that way. Continuity matters to us, so the same finish accents every steel detail in the home, from the fireplace framework to the custom timber washers that secure the reclaimed-wood mantel. Even the four-thousand-pound bookcase – finished off-site and craned into position near project completion – carries the identical treatment, ensuring the finish reads as a single, intentional design language throughout.

Details matter – the finished concrete fireplace included custom patina-finished steel elements including wood storage on both sides, a front faceplate with matching hardware, and decorative chimney shroud to hide the actual stainless chimney piping inside.

What This Project Represents

Transforming a brief video clip into a signature architectural element illustrates three Falcon Heights hallmarks: innovation rooted in rigorous research, collaboration with skilled trade partners, and craftsmanship defined by exacting execution. By welcoming a mid-stream challenge – and obsessing over every test, timing interval, and environmental control – we delivered a finish that will endure and evolve as gracefully as the rest of the home.
