Developments & Real Estate
The wellness suite that looks like the render and runs like the spec.
Cold water immersion designed into the build, not bolted on after: plant out of sight, finishes to the scheme, performance specified once and held for the life of the asset. Done at drawing stage, it's a line on the plan. Done after, it's a retrofit, and that difference is thousands.
Month thirty-six is too late.
Most wellness gets into a development the same way: the design is set, the building is underway, and somewhere around month thirty-six someone adds a cold plunge to the spec. It photographs well in the brochure. But specced that late, it's a retrofit system disconnected from the plant room, an M&E headache, thousands extra in build and earning nothing it could have earned as a decision planned for at the start. As a guide, a configured system is typically a five-figure installation; a fully bespoke build runs to six figures.
Price it into the underwriting.
The schemes getting it right aren't adding wellness at the end. They're pricing it in at master-plan stage, because that's where it changes the value of the building as well as the look of the amenity floor. The Global Wellness Institute's Build Well to Live Well (Vol 2, May 2026) documents a 10–25% price premium on wellness-positioned residential property at the middle and upper ends of the market, and a 4.4–7.7% commercial rental premium. GWI's own worked illustration: on a $200M residential build, a ~15% premium is roughly $30M of gross asset value against a $5–10M wellness integration. Their numbers, not ours, but the direction is clear. Wellness is moving from amenity-at-the-end to underwriting-at-day-one. Run properly, cold water immersion is readiness infrastructure: the stress training your residents and guests are already reading about, engineered into the building like any other system.

Drawn in, not dropped in.
Brass Monkey builds the freestanding or integrated system designed to run to your environment, so cold water immersion can be specified at design stage and priced in like any other piece of infrastructure, not squeezed into FF&E as a standalone object. Every system connects through HALO: live telemetry covering temperature, uptime and system status, with remote diagnostics and fleet-level monitoring across a scheme or a portfolio. Designed and built in Britain, supported by UK engineers, serviceable for the life of the asset. Two of those capabilities are hard to find anywhere else. Spa-grade freestanding systems, plug-and-play installation carrying a high daily user load, nobody else builds. And fully custom work, meaning headless plant-room builds, bespoke finishing and dry-cooled systems for spaces where conventional cooling can't go, very few can follow. At specification stage we supply the M&E schematics, power and water requirements and plant layout your design team needs, so it goes on the drawings like any other building service.
A standard your asset can stand on.
The Cold Standard is how cold water immersion is done properly: science, infrastructure, governance. For a development, the weight sits on infrastructure and governance.
Infrastructure: the headless plant-room system plus the connected layer, specifiable at design stage and serviceable for the life of the asset, not a retrofitted object.
Governance: a clear safety floor for resident, member or guest use, structured handover and trained delivery for the operator partner and post-sale service through ProCare.
That's what lets you put cold into a scheme in front of an operator or an insurer, with a standard behind it they can check.
The system that's specified to the scheme.
What's on the drawing has to match the customer experience. For most schemes the approach is a headless system run to the plant room, dry-cooled, the vessel finished to the scheme's own palette, cold water immersion specified like any other building service. For high-throughput amenity floors, a spa level serving a whole development, the freestanding Spa range installs plug-and-play and is engineered for up to 400 users a day. For a smaller residents' gym, the Pro range carries the same standard at up to 75 users a day. Three ways in, one standard, sized to the building and the life it's designed for.
Installed where the standards are being set.
A residents' gym or a spa level runs on the same questions as any commercial floor, whoever ends up operating it. Specifying Readiness is our guide to answering them at drawing stage. It works through the four things that decide most installs: the space, the demand, the water plan and the experience. That way cold water immersion goes on the plan with the hard questions already settled.
