What this work involves
Establish existing service routes, levels, ground conditions and access before planning excavation.
- Excavation boundaries
- Removal and reuse of soil
- Levels and surrounding connections
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Coordinate larger openings with the useful wall sections that remain.
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
Costs depend on soil volume, access and disposal arrangements. 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 groundworks & site preparation. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging groundworks & site preparation?
Even a small extension may need groundworks. Foundation design, existing landscaping and service routes determine the extent.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
