Treatment rooms in London
Describe the activity before choosing a building. Client entry, privacy, cleaning, ventilation, services and any relevant permissions belong in the brief. Plan the treatment furniture in use and discuss requirements with Oeco.
Planning your London project
Position a desk or seating so the view works from inside the room. If neighbours overlook the proposed position, discuss glazing orientation and screening before choosing a design.
Use the property address to find the relevant borough or local planning authority. Garden access, neighbouring windows and space for services can be as important as the footprint itself. Photograph the full route from the street to the proposed position, including passages, turns and changes of level.
Find the authority for your London propertyLondon planning decisions are handled by the relevant local planning authority. Use your property address to find the borough or authority responsible, alongside London-wide information.
Council information ↗ Find your council ↗Make the space work
Plan the route from arrival to the room, space around the treatment couch or consultation desk, and a private place for changing or storing belongings. Keep clean supplies, used items and paperwork organised without blocking circulation.
Discuss handwashing, ventilation, privacy, lighting and any WC requirements early. Visiting clients, operating hours and business activity may affect planning and other professional requirements. Put these into the brief before choosing a domestic leisure-room layout.
Describe the treatment or service, equipment sizes, client numbers, accessibility needs and water or drainage requirements. Keep clinical and regulatory requirements with the appropriate professional advisers while Oeco discusses the building and installation.
What shapes the quote? Plumbing, a WC, specialist ventilation, privacy measures and access requirements can materially change a treatment-room project. Compare the building, foundations, installation and house-to-room connections as one project.

A useful local starting point
