Garden annexes in Lancaster

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

Homes in the North West

Across the North West, Victorian terraces, inter-war semis and modern estates all feature, and brick or stone matching is chosen to suit each street.

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.

  • Brick, block or timber-frame structure
  • Heating, hot water and electrics
  • Accessible design options for older relatives

How is a garden annexe approved in Lancaster?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it 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 I think about before starting?

  • 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.

What happens after I enquire?

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
