What’s the process for converting a double garage to a granny flat in Bedfordshire?

Converting a double garage into a granny flat in Bedfordshire usually means creating a self-contained annexe with its own living space, bathroom and kitchenette, so planning permission is more likely to be needed than for a simple room conversion. The process runs: confirm the planning position with the council, design the layout, apply for Building Regulations approval, then complete the build with insulation, damp-proofing, heating, ventilation, electrics and compliant drainage. A double garage gives enough floor area for a comfortable, independent space for a relative. See a real example in our self-contained annexe project, or explore detached garage conversions if the annexe is separate from the house.
