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.
Test extra floor area against simultaneous cooking, play and work.
Which trade-off matters?
An open living space makes contact easy but offers less separation for sound and work. Compare a fully open plan with closable zones while retaining clear routes to the kitchen and stairs.
What the drawing needs to explain
Show furniture, door swings and circulation on one plan. Mark a quiet workspace and the places where several people pass at once.
Decide this before construction
Decide which room remains available for quiet and study during the work. Do not automatically schedule kitchen and bathroom disruption in the same phase.
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.
