Adding an en-suite to a South Hampstead bedroom is mostly an exercise in drainage and space. The new bathroom has to find a few square metres — from the bedroom, a landing or a cupboard — and then connect to a soil stack that may be some distance away, all within the depth of a period floor or the constraints of a conversion flat.
Waterproofing is the other non-negotiable. A bathroom built over a period timber floor must be properly tanked and detailed so it never leaks into the room — or the flat — below, and pipework has to be routed without butchering joists. In a leasehold flat, alterations to services usually need freeholder consent as well.
We plan the en-suite to take the least space for the most function, resolve the drainage and waterproofing properly, secure any consents, and fit it out — tiling, screens, heating, ventilation — in one contract, to the standard the rest of the home deserves, with honest budgets in pounds sterling.
