What this work involves
Position the bed, desk or storage first. Width alone says little without the dormer's position in the roof and the resulting headroom. Coordinate the design with the existing roof and room ventilation.
- Position and dimensions
- External material and finish
- Window arrangement and ventilation
- Roof and insulation connections
- Internal finishing, electrics and shading
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Include intended interior details in the design of additional space.
Which trade-off matters?
A minimal joint or concealed fixing may need extra coordination. Compare the intended appearance with tolerances, maintenance and replaceability before treating a detail as straightforward.
What the drawing needs to explain
Draw one bespoke junction at a large scale with every adjoining finish layer. Identify who takes final dimensions and which substrate must be ready for that measurement.
Decide this before construction
Approve material combinations and the sample detail before production. Complete work affecting dimensions before ordering final bespoke components.
Cost factors for this service
Dimensions, construction, access and internal finishing influence the price. Compare the same scope: lining and painting are not always included.
Bring this to the discussion
Photographs of the roof and loft, desired width and a sketch of the room.
Questions about the work
Is internal finishing included?
That depends on the proposal. Ask for window boards, lining, plastering, painting and electrical changes to be specified if you want a finished room.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
