Extensions in and around Ilkeston
We cover Ilkeston and the postcode districts DE7. Neighbouring towns we cover include Heanor (4 miles), Long Eaton (5 miles), Ripley (6 miles), Derby (8 miles).
Eastwood, in Nottinghamshire, is roughly 2 miles from Ilkeston and also on our list. Homes across the East Midlands often have usable side land or a driveway beside the house, which opens up side and wraparound options.
Do I need planning permission in Ilkeston?
In England the main routes are permitted development (ideally confirmed with a lawful development certificate, £274), larger home extension prior approval (£249, 42 days) and a householder planning application (£548, normally 8 weeks), with council fees as set from 1 April 2026.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).

Who this service is for
- Anyone who wants fixed designs before getting build prices
- Projects that need a planning application or other approval
- Homeowners at the very start of a project
The most expensive changes are the ones made after the steel is ordered. A good design stage settles layout, heights, glazing and services on paper, so the build price is firm.

Questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Ilkeston, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Ilkeston?
Yes. We cover Ilkeston and the surrounding parts of Derbyshire. Site visits are free and there is no obligation.
Will my neighbours in Ilkeston be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Can I use your drawings with another builder?
Yes. Once paid for, the drawings are yours to use for your project.
How much do extension plans cost?
Our design packs range from about £1,100 to £5,250 including VAT, from planning drawings only to a full pack with building regulations drawings, structural calculations and 3D views. Council fees are separate.
