A side-return extension fills part of the narrow strip alongside a house, often next to an existing kitchen. The extra width can change how the whole ground floor works. Before booking a measured survey, walk through these five decisions and make a few notes about what you want the new space to do.
1. Follow your route through the house
Walk from the front door to the kitchen and garden as you would on an ordinary day. Note where coats, shoes, bins and shopping currently go. If you use the side passage for bikes, bins or garden access, decide where those things would go if the passage were built over. Photograph the route from both ends.
2. Decide what should happen in the middle room
Extending behind a dining or sitting room can leave that room deeper inside the house. Think about whether you want it to stay separate, open into the kitchen or work as a quieter space. Photograph the existing room in daylight with the lights off and note which windows light it now. That gives your designer a starting point for comparing openings, glazing and rooflights.
3. Sketch the furniture before choosing the doors
Mark your preferred dining table, island or peninsula on a rough sketch. Add chairs in use and show which way you want to walk to the garden. A large opening can look generous on an elevation while leaving little useful wall for storage. An early furniture layout helps you compare options before settling on a door position.
4. Photograph the boundary and drainage features
From your own property, take photos of the side wall, boundary, downpipes and any visible inspection covers. If the garden and kitchen floors sit at different levels, include a photo of the step. These details help flag where specialist input may be needed. We prepare planning drawings and can quote for Building Regulations working drawings on suitable projects where we prepared and submitted the planning drawings. A structural engineer can be commissioned separately where structural design is needed.
5. Write down what you would keep if the scope changed
List the two things the extension must deliver and the features you could drop. You might need a family dining table and easier garden access, for example, with an island as an optional extra. That makes it easier to test a smaller proposal if the available space, budget or site constraints limit the first idea.
What to send for a quote
Send your postcode, a few photos and a short note about what you want the extension to achieve. An estate-agent floor plan or hand sketch is helpful if you have one.
