Local to Woodford Green
We cover Woodford Green and the postcode districts E4, E18, IG8. We also work in nearby Chingford (2 miles), Walthamstow (2 miles), Leytonstone (3 miles), Edmonton (4 miles).
Just over the Essex border, Waltham Abbey is about 5 miles away. 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.

Will the council need to approve it?
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.
The planning position for a specific Woodford Green address depends on its history and any designations, which is why we check it at the first visit.
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).
Included in a typical project
- Aluminium or timber lantern and full-height glazing
- Thermal calculations where glazing is generous
- Heating sized for the glass area
- Opening into the main house
- Foundations, walls and insulated perimeter roof
The lantern-to-roof ratio sets the character. A wider solid perimeter gives a calmer, more room-like space and hides downlights and speakers; a bigger lantern feels brighter but needs more care against summer heat.

Orangery extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Woodford Green, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Will my neighbours in Woodford Green 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 I need building regulations approval in Woodford Green?
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 Woodford Green.
