What this work involves
Start with the space you need in daily life. Place furniture and walking routes on the plan before deciding the external dimensions. A deeper extension is not automatically better: daylight in the existing part deserves equal attention.
- Dimensions and position of the extension
- Existing rear wall and structural changes
- Foundation, floor build-up and connection to the house
- Glazing, rooflights, shading and ventilation
- Kitchen, heating and electrical layout
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Compare extension with a smarter combination of glazing and storage.
Which trade-off matters?
A larger glazed area can visually open the room but remove useful wall space. Compare window divisions and bespoke storage together, including curtains or other screening.
What the drawing needs to explain
Draw fixed furniture, sightlines and opening windows together. Allow room for screening so it does not later obstruct cupboards, heaters or passages.
Decide this before construction
Choose layout and storage needs before fixing window divisions. Then coordinate lighting and connection points with the remaining usable walls.
Cost factors for this service
Size, foundation method, access, structural work and finishes determine the budget. Ask for drawings, installations, demolition and garden reinstatement to be identified separately.
Bring this to the discussion
A floor plan, photographs, approximate dimensions and a short list of requirements.
Questions about the work
Can I stay at home during the extension?
It depends on the work. Discuss when the existing wall is opened, how the house is protected from dust and rain, and which facilities become unavailable.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
