Garden annexes in Canterbury

Planning garden annexes in Canterbury? We design and build them for houses across Kent, and we fix the price for the agreed specification in writing before any building work starts.

Covering Canterbury

We work in Canterbury (CT1) and the places around it, including Whitstable, Herne Bay and Faversham.

Homes in the South East

The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.

What do you get with a garden annexe?

We design annexes as permanent buildings with proper foundations, insulation and services, and we prepare the planning case showing how the annexe will be used as part of the main home. Connections for water, drainage and power are planned from the start.

  • Foundations and drainage connections
  • Heating, hot water and electrics
  • Accessible design options for older relatives

Do you need permission for a garden annexe in Canterbury?

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

A self-contained annexe used for sleeping and living normally needs planning permission in England.

What should Canterbury homeowners check first?

  • Drainage may need a pump if the garden falls away from the sewer.
  • A level threshold and wider doors make the annexe suitable for later life.

What happens after I enquire?

  1. Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
  2. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  3. Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.

Your questions answered

Do I need planning permission for a garden annexe?

Usually yes, because people will sleep in it. Outbuilding permitted development does not cover living accommodation.

Can I rent the annexe out?

Usually not without a separate planning permission, because councils normally require it to stay part of the main house.

Can you visit a house in Canterbury to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
