Independent living, close to home
A proper home within your garden.
A garden annexe can bring a living area, kitchenette, bathroom and bedroom into one self-contained space. Plan it around the person who will live there, their routines, privacy and changing access needs.
Oeco offers bespoke garden annexes with residential layouts. These are a different project from an office, gym or leisure room.
Interior inspiration
Discuss a garden annexeEveryday living
Decide whether you need one or two bedrooms, a separate lounge, a kitchen or kitchenette and a shower room. Plan furniture, storage and clear circulation as carefully as the room divisions.
Comfort and independence
Think about the route from the main house, door openings, bathroom access, lighting and easy-to-use controls. Bring specific accessibility requirements into the design discussion from the start.
Residential services
Water, drainage, electricity, heating and ventilation belong in the initial brief. Explain who will occupy the annexe and how it relates to the main home so the correct planning and building requirements can be established.
Annexes and ordinary garden rooms follow different briefs.
Planning Portal’s outbuilding guidance does not cover separate self-contained living accommodation. Start with the residential use and the property’s planning authority, then develop the building and service specification. An annexe intended for family accommodation should not be assumed to be authorised for separate letting.
Planning your London project
Plan privacy and daylight together.
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.
London: identify the authority for your address
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.

London 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.

Plan your garden annexe in London.
A home planned around its resident
Start with the bedroom, bathroom, kitchen and living space, then check furniture, storage and routes between them. Discuss door openings, shower access and the path to the main house around the person who will live here.
Residential comfort and services
Plan the water, drainage, electricity, heating and ventilation together. Explain the intended occupation and relationship with the main home so Oeco can discuss the appropriate residential specification and installation requirements.
A complete annexe brief
Include who will occupy the annexe, the rooms required, any accessibility needs and the available footprint. Add photographs of the site and access. Establish planning and building requirements for living accommodation before treating the design as ready to order.
What shapes the quote? Room divisions, kitchen and bathroom fit-out, service connections, access requirements and the residential specification shape an annexe project. Compare the building, foundations, installation and house-to-room connections as one project.

A useful local starting point
Make the footprint and glazing work together.
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.
