Planning and approvals in Alfreton
In England a single-storey side return infill is often permitted development if it stays within the height limits and is no wider than half the width of the original house. Conservation areas, listed buildings and flats always need an application, and the boundary wall usually brings in the Party Wall Act.
The planning position for a specific Alfreton address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
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).
Extensions in and around Alfreton
Our survey diary covers Alfreton, including DE55. We also work in nearby Ripley (4 miles), Heanor (6 miles), Belper (7 miles), Ilkeston (9 miles).
Homes across the East Midlands often have usable side land or a driveway beside the house, which opens up side and wraparound options.
Included in a typical project
- Kitchen-ready shell or full finish
- New boundary wall or raised party wall
- Party wall notice support (England and Wales)
- Glazed, sloping or flat roof with rooflights
- Removal of the side wall and new steelwork
Light is the design problem. A side return can make the middle of the house darker if the roof is solid, so we model the daylight and usually recommend a glazed slope or a run of rooflights along the boundary edge.

Common questions in Alfreton
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Alfreton, 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 Alfreton?
Yes. We cover Alfreton and the surrounding parts of Derbyshire. Site visits are free and there is no obligation.
Do I need building regulations approval in Alfreton?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can I combine a side return with a rear extension?
Yes. That combination is a wraparound extension, which adds the most space to a terraced house.
Do side return extensions need planning permission?
In England many single-storey side returns fit within permitted development if they stay within the height limits and are no wider than half the width of the original house. Conservation areas, listed buildings and flats need an application. Other UK nations have their own rules, which we check.
