Orangery extensions across Pinner

From the first sketch to final sign-off, we plan and build orangery extensions in Pinner and the surrounding Greater London area.

What is included

  • Aluminium or timber lantern and full-height glazing
  • Design of piers, roof perimeter and lantern proportions
  • Opening into the main house
  • Thermal calculations where glazing is generous

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.

Do I need planning permission in Pinner?

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.

Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.

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.

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).

Extensions in and around Pinner

Site visits are available across Pinner (HA2, HA5). The same team covers Wealdstone (2 miles), Ruislip (2 miles), Harrow (2 miles), South Ruislip (3 miles), all within easy reach.

For homes towards Hertfordshire, Bushey is around 4 miles away. 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.

How the project works

Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

  1. Free site visit

    First, a site visit: we look at the house, garden, access and drains and listen to what you need.

  2. Design and approvals

    Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.

  3. Fixed written price

    You receive a written, itemised price and programme. Nothing starts until you are happy with it.

  4. Build and sign-off

    Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.

How long does an orangery extension take to build in Pinner?

On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.

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.

Yes. We cover Pinner and the surrounding parts of Greater London. Site visits are free and there is no obligation.
