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.
Decide how new materials will age beside existing ones in an addition.
Which trade-off matters?
Uniform colour and low maintenance are not automatically the same choice. Compare a coated surface with a material allowed to change visibly, including access for future maintenance.
What the drawing needs to explain
Detail the lower edge and the junction with another material. Show where water can drain and how an element can be replaced without opening the entire finish.
Decide this before construction
Select the material early enough to design edges and fixings around it. Review a sample in its intended location before placing the full order.
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.
