Frequently Asked Questions

  • The cost to build a 1 bed annexe depends on its size, layout, specification and site conditions. One bedroom granny annexes typically vary in price based on internal floor area, level of finish and any required groundworks. Clear pricing for each one bedroom model is shown on this page.

  • The size of a granny annexe should be large enough to comfortably accommodate a bedroom, bathroom and living area. For a one bedroom layout, this typically means allowing sufficient space for independent living while remaining proportionate to the garden and compliant with local planning guidance.

  • Some granny annexes can be built under permitted development, while others require planning permission. This depends on factors such as size, height, location and how the annexe will be used. Planning requirements can vary by local authority, so it is always important to check before building.
