Garden annexes in Yate

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

Covering Yate

Yate sits 24 miles south of Gloucester, with Kingswood 7 miles to the south-west and Bath 12 miles to the south.

Homes in the South West

The South West mixes stone and render cottages, Victorian terraces in the larger towns and modern estates, and many historic centres are conservation areas where materials and roof shapes are closely controlled.

What does a garden annexe involve?

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.

  • Brick, block or timber-frame structure

Planning and building rules in Yate

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.

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 Yate homeowners check first?

  • The annexe normally has to remain part of the main household, not let as a separate home.
  • Drainage may need a pump if the garden falls away from the sewer.

What are the steps?

  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.
