Extensions in and around Enfield
Across EN1, EN2, EN3, N9, N14, N21, we can visit, measure and advise. Nearby, we also take on projects in Ponders End (2 miles), Edmonton (2 miles), Palmers Green (3 miles), Enfield Lock (3 miles).
In London, space is at a premium and gardens are often short, so side returns, wraparounds and carefully planned rear extensions tend to make the most of every metre.
Planning and approvals in Enfield
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 Enfield 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).

Common questions in Enfield
Do I need building regulations approval in Enfield?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How long does an orangery extension take to build in Enfield?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Will my neighbours in Enfield 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.
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.
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 Enfield.
