Basement and cellar conversions in South Shields

We take on basement and cellar conversions in South Shields as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering South Shields

Our coverage around South Shields (NE33) also includes Tynemouth, North Shields and Jarrow.

Homes in the North East

In the North East, terraces, semis and bungalows all offer room to extend, with stone-built villages and conservation areas in parts of County Durham and Northumberland.

What does a basement conversion involve?

Everything below ground depends on keeping water out. We design the waterproofing system (usually a cavity drain membrane with a pump, or tanking) to the relevant British Standard guidance, then add insulation, ventilation, light and an escape route. New basements involve underpinning and a party wall process and are designed with a structural engineer.

  • Damp and structural survey
  • Underpinning or lowering the floor where needed
  • Ventilation, heating and electrics

Planning and building rules in South Shields

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

Converting an existing cellar with no external changes usually does not need planning permission in England. Digging a new basement or adding a lightwell often does, and many councils have basement policies.

What can affect a basement conversion?

  • Groundwater levels drive the waterproofing design and cost.
  • Headroom of about 2.1 m or more is needed, which may mean lowering the floor.

From first call to completion

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
  4. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
