A downstairs cloakroom is one of the most useful additions to a South Hampstead villa or flat, but it is almost always a puzzle of tight space and drainage. The obvious spot — under the stairs, off the hall, beside the kitchen — is usually small and far from a soil stack, so the planning matters more than the fittings.
Where gravity drainage cannot reach, a concealed macerator or pump makes the WC possible without major works; where it can, we connect properly to the existing stack. In a conversion or mansion flat the stack is shared, so the connection has to respect the building and the neighbours, and the room needs reliable ventilation because a small internal WC has no natural airflow.
We design the cloakroom to use every inch, build any joinery bespoke to the space, and handle the drainage, electrics, ventilation and finishes in one tidy contract — a small room done to the same standard as a large one, with honest budgets in pounds sterling.
A cloakroom is a small room with big technical questions — drainage and ventilation lead the design.
Distance to the soil stack determines whether it is a gravity connection or a concealed macerator/pump.
A small internal WC needs proper extraction; we design it in rather than leave it stuffy.
Bespoke joinery and compact fittings make an understairs or box space genuinely usable.
In a conversion or mansion flat the soil stack is shared, so the connection respects the building and neighbours.
