Planning and approvals in Braintree

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.

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).

Local to Braintree

Across CM7, CM77, we can visit, measure and advise. Neighbouring towns we cover include Witham (7 miles), Chelmsford (10 miles), Maldon (11 miles), Colchester (15 miles).

Just over the Suffolk border, Sudbury is about 13 miles away. Across the East of England many houses sit on generous plots, and single-storey and wraparound extensions are a natural fit.

Included in a typical project

  • Thermal calculations where glazing is generous
  • Opening into the main house
  • Design of piers, roof perimeter and lantern proportions
  • Foundations, walls and insulated perimeter roof
  • Heating sized for the glass area
  • 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

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

  2. Design and approvals

    We draw the design, agree it with you and handle planning or permitted development checks and building regulations.

  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

    The build is managed from start to finish, inspected at each stage and signed off on completion.

Common questions in Braintree

Do I need building regulations approval in Braintree?

Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.

Can I see a price before committing to anything?

Yes. The guide prices on this page are adjusted for Braintree, 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 Braintree 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.

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.

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.
