Saunas & cold plunges in Victoria Island

The lift, the slab, the membrane

Three checks before any price: the service lift's height, width and diagonal; the terrace slab's capacity for something close to a tonne of water; and whether the existing waterproof membrane was ever designed to live under a permanently wet installation.

Panels are then built to pass the lift with room to turn. A panel that fits the drawing but not the lift is an expensive afternoon, and we would rather spend twenty minutes measuring.

Drainage nobody planned for

A terrace gully sized for rainwater is not automatically sized for a full tub emptying. We design the discharge properly, because water finding its way into the apartment below is the single most expensive failure available on a tower terrace.

Hotels that cannot go dark

For the hotel work here the defining requirement is continuity: every guest-facing load — heater, chiller, lighting, extract — on circuits the changeover feeds, and sequenced so a generator start does not trip on inrush.

A spa that goes dark at seven on a Friday is a spa guests stop booking, regardless of how good the mosaic is.
