Double-storey extensions in Ilkeston

Homeowners in Ilkeston can get double-storey extensions from one company: the design, the paperwork and the building work sit with us rather than with three separate firms.

Covering Ilkeston

Ilkeston is about 8 miles north-east of Derby. We also cover Heanor (4 miles to the north-west), Long Eaton and Ripley.

Homes in the East Midlands

The East Midlands combines red-brick terraces in the cities with a lot of post-war and modern estate housing, so rear extensions, garage conversions and loft conversions are all common.

What does a double-storey extension involve?

A double-storey extension adds new rooms on both the ground and first floor in one build, typically a larger kitchen or living space downstairs and an extra bedroom or bathroom above. Because the roof and foundations are shared, the cost per square metre is usually lower than a single-storey extension.

  • Measured survey, design and planning drawings
  • Structural engineer’s design and calculations
  • Joining the new first floor to the existing landing

Do you need permission for a double-storey extension in Ilkeston?

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.

Two-storey rear extensions can sometimes be permitted development in England (no more than 3 m deep, at least 7 m from the rear boundary, roof pitch to match), but most two-storey and all two-storey side extensions need householder planning permission. Expect around eight weeks for a decision once the application is validated.

What can change the price or programme?

  • Side extensions close to a boundary are often set back or stepped down so they do not create a terraced effect.
  • The first-floor link can mean moving a bathroom or reshaping the landing.
