What this work involves

- Stairs, daylight and ventilation
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Coordinate the structure with the proposed opening to the garden.
What the drawing needs to explain
Draw one section through the kitchen, glazing and terrace. Include finished floor levels, the roof edge and shading position; separate supplier sketches do not fully show these relationships.
Decide this before construction
Fix the kitchen layout and finished floor levels before ordering services and glazing. Plan the outdoor transition too, even when garden work will follow later.
Cost factors for this service
Costs depend on depth, foundation alterations, water management and access. Ask for the scope and selected specification to be described separately.
Bring this to the discussion
Photographs of the existing situation, available drawings and your requirements for basement construction. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging basement construction?
A basement is not feasible beneath every home. Specialist assessment must establish whether the proposed work can be carried out appropriately.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
