Garden annexes in Cumbria

Covering Cumbria

We cover Cumbria, including Carlisle, Barrow-in-Furness, Kendal and Whitehaven, and the towns around them.

Because Cumbria covers a wide area, we confirm availability after the first call and include any travel costs in the written quote rather than adding them later.

Homes in the North West

Terraced housing is a defining feature of many North West towns, which brings party walls and narrow access into most projects, with more space to extend on suburban semis.

What is included in a garden annexe in Cumbria?

A garden annexe is a separate single-storey building in the grounds of a house with its own bedroom, bathroom and kitchenette, used by family members as part of the main household. Unlike a garden office, an annexe that people sleep in normally needs planning permission and full building regulations approval.

Planning and building rules in Cumbria

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?

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?

Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.

Garden annexes: common questions

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.

Who deals with the council for a project in Cumbria?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
