Covering Newark-on-Trent
Across NG24, we can visit, measure and advise. Neighbouring towns we cover include Arnold (14 miles), Nottingham (16 miles), West Bridgford (16 miles), Hucknall (16 miles).
Grantham, in Lincolnshire, is roughly 13 miles from Newark-on-Trent 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.
Planning rules that apply in Newark-on-Trent
In England a glazed or orangery-style extension follows the same size limits as any single-storey rear extension: 3 m or 4 m without an application, or up to 6 m and 8 m through prior approval. Building regulations limit glazing to about a quarter of the new floor area plus the openings it replaces, unless whole-house calculations show the design still performs.
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.
Applications are decided by the local planning authority (your district, borough or unitary council).

Questions people ask about glass extensions
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Newark-on-Trent, 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 Newark-on-Trent?
Yes. We cover Newark-on-Trent and the surrounding parts of Nottinghamshire. Site visits are free and there is no obligation.
Do I need building regulations approval in Newark-on-Trent?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How much does a glass extension cost?
Our guide range is about £2,850 to £5,510 per m² including VAT, because structural glass is made to order. A 12 m² standard-spec glass extension is typically £39,500 to £50,500 in Newark-on-Trent.
Are glass extensions cold in winter?
Modern double or triple glazing with warm-edge spacers and underfloor heating keeps them comfortable. They are not as warm as a solid room, and we explain the trade-off honestly.
