Garden annexes in Doncaster

We take on garden annexes in Doncaster as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering Doncaster

Our coverage around Doncaster (DN1, DN2, DN55) also includes Bentley, Rotherham and Pontefract.

Homes in Yorkshire and the Humber

Across Yorkshire and the Humber, older stone and brick terraces sit alongside inter-war semis and newer estates, and dormers and rear extensions are designed to suit each.

What is 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.

  • Design and planning application
  • Brick, block or timber-frame structure
  • Heating, hot water and electrics

How much should I budget for a garden annexe?

Guide prices for garden annexes, including VAT where it applies. Your fixed price is confirmed in writing after the survey.

Do you need permission for a garden annexe in Doncaster?

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. Permitted development for outbuildings does not cover living accommodation.

What should Doncaster homeowners check first?

  • Drainage may need a pump if the garden falls away from the sewer.
  • Council tax treatment depends on who lives there; check with your council.

From first call to completion

  1. Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
  4. Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
