Working in East Molesey
Across KT7, KT8, we can visit, measure and advise. We also work in nearby West Molesey (1 mile), Esher (2 miles), Walton-on-Thames (3 miles), Sunbury-on-Thames (3 miles).
For homes towards Greater London, Hampton is around 1 mile away. In the South East, plenty of houses have already been extended once, which makes checking the remaining permitted development allowance an important early step.
Planning and approvals in East Molesey
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.
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).
What we take care of
- Foundations, walls and insulated perimeter roof
- Thermal calculations where glazing is generous
- Design of piers, roof perimeter and lantern proportions
- Aluminium or timber lantern and full-height glazing
- Opening into the main house
- Heating sized for the glass area

Questions people ask about orangery extensions
Who do I contract with for an orangery extension in East Molesey?
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.
How long does an orangery extension take to build in East Molesey?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Do you cover all of East Molesey?
Yes. We cover East Molesey and the surrounding parts of Surrey. Site visits are free and there is no obligation.
Does an orangery need planning permission?
It follows the same size limits as other single-storey extensions. In England many fit within permitted development or prior approval; others need an application.
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.
