Family rooms in London
Think about who will use the room and its view from the house. Plan furniture, storage and glazing around games, reading or shared downtime. A flexible layout can support several activities while keeping useful space clear.
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
Arrange seating, play space and storage as separate zones. Check how the room connects to the house and garden, how the doors open and where shoes, toys or hobby equipment will live. Flexible furniture helps a shared room change through the day.
Balance views out with privacy from neighbours. Think about heating controls, ventilation and lighting for both daytime activities and quieter evenings. Choose surfaces and storage around the people who will actually use the room.
Tell Oeco who will use the space, the main activities and whether the room needs to switch from play to study or relaxing. Sleeping or self-contained accommodation needs an annexe brief rather than an ordinary leisure-room specification.
What shapes the quote? Glazing, heating, storage, room divisions and the overall furniture footprint shape family-room decisions. Compare the building, foundations, installation and house-to-room connections as one project.

Your project

Start with the activities that need the most space, then allow clear circulation and practical storage. Consider the view from the house and where seating or play areas will sit relative to glazing.
Flexible furniture and well-positioned sockets can help. Keep the primary use clear when choosing the initial building specification and confirm future requirements before assuming a different activity will be suitable.
Your postcode, intended use, approximate space and photographs of the position and access route. Discuss the chosen range and final specification with Oeco.
Oeco’s indoor showrooms are in Ripon, where you can compare the buildings and finishes.
Oeco provides your quotation, customer contract, installation and aftercare. Ask for the size, specification and inclusions in writing before ordering.

Another way to use the space
A useful local starting point
Measure patio space, boundaries and the usable garden around the room. Think about privacy as well as daylight when positioning doors and windows. The London installation below uses an existing patio and corner glazing to open up a 4m × 3m room.
