Garden rooms & granny annexes: areas we cover
Find your area, then explore a garden room for work and leisure or an annexe designed for independent living. Each guide connects design ideas with real projects, specifications and practical planning advice.
These are service areas, not branch offices. Every project starts with a site-specific assessment. The groups below help you browse; use your property postcode to confirm the responsible planning authority.
