Local to Essex

Towns we cover in Essex include Southend-on-Sea, Basildon, Colchester, Chelmsford, Harlow, Grays, Braintree, Brentwood. The East of England mixes market-town terraces, inter-war semis and modern estates. Clay soils are common in parts of the region, which can affect foundation design.

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.

In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.

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.

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

  • Thermal calculations where glazing is generous
  • Heating sized for the glass area
  • Foundations, walls and insulated perimeter roof
  • Aluminium or timber lantern and full-height glazing

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.

From first visit to completion

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

    We visit your Essex home, measure up, talk through what you want and check the planning position.

  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

    The price is fixed in writing once the design is settled, with a clear programme and payment stages.

  4. Build and sign-off

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

Your questions about an orangery extension in Essex

Who do I contract with for an orangery extension in Essex?

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.

Do you cover all of Essex?

Yes, across the whole of Essex. Site visits are free and there is no obligation.

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

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

What is the difference between an orangery and a conservatory?

An orangery has a solid roof perimeter with a central lantern and more solid wall, so it is warmer and more like a room. A conservatory is mostly glass. Building regulations treat a heated orangery joined to the house as an extension.

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.
