Extensions in and around Worcester Park
Site visits are available across Worcester Park (KT3, KT4, SM3). The same team covers New Malden (2 miles), Morden (2 miles), Surbiton (2 miles), Hook (3 miles), all within easy reach.
Ewell, in Surrey, is roughly 2 miles from Worcester Park and also on our list. Across London, terraced houses with narrow side returns and tight access are the norm, which shapes everything from party wall notices to how materials reach the back garden.
Planning rules that apply in Worcester Park
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 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).
Included in a typical project
- Thermal calculations where glazing is generous
- Heating sized for the glass area
- Design of piers, roof perimeter and lantern proportions
- Opening into the main house
- Foundations, walls and insulated perimeter roof
- Aluminium or timber lantern and full-height glazing

Orangery extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Worcester Park, 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 Worcester Park?
Yes. We cover Worcester Park and the surrounding parts of Greater London. Site visits are free and there is no obligation.
Do I need building regulations approval in Worcester Park?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
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 £3,120 to £5,850 per m² including VAT, so a 16 m² standard-spec orangery is typically £58,000 to £73,000 in Worcester Park.
