Extensions in and around Esher
Postcode districts we cover around Esher include KT7, KT8, KT10, KT12. The same team covers East Molesey (2 miles), West Molesey (2 miles), Walton-on-Thames (2 miles), Sunbury-on-Thames (3 miles), all within easy reach.
Just over the Greater London border, Hook is about 3 miles away. The South East has a broad mix of 1930s semis, post-war estates, newer developments and period cottages, and many houses have enough garden for a generous rear extension.

Planning and approvals in Esher
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.
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.
Applications are decided by the local planning authority (your district, borough or unitary council).

Orangery extension questions answered
Who do I contract with for an orangery extension in Esher?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Will my neighbours in Esher 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.
Do you cover all of Esher?
Yes. We cover Esher and the surrounding parts of Surrey. Site visits are free and there is no obligation.
Will an orangery be too hot in summer?
Not if it is designed with solar-control glass, a solid perimeter and ventilation. We size the lantern and opening vents with that in mind.
How much does an orangery cost?
Our guide range is about £2,690 to £5,040 per m² including VAT, so a 16 m² standard-spec orangery is typically £50,000 to £63,000 in Esher.
