Common questions

About garden rooms in Grantchester.

Do I need planning permission for a garden room?
Most garden rooms fall within permitted development if they're under 30m², no taller than 2.5m at the boundary, and within 50% of the curtilage. Listed properties and conservation areas have extra rules — we'll check the specifics.
How long does a garden room take to build?
Six to ten weeks on site for a typical 15–25m² office or studio. Larger rooms with services and complex access run longer.
How much does a Grantchester garden room cost?
Insulated, fully-finished garden rooms built to house standards typically run £2,400–£3,500 per m². A 20m² office sits around £50k–£70k including foundations, services and joinery.
Can it have a bathroom or kitchenette?
Yes — drainage and water supply usually require a trench from the main house. We handle the foul, water, and electrics together.
