Garden rooms in Barnet.

A garden room in Barnet can create a dedicated workplace, a private gym or a more flexible family space. Cedar Spaces serves the area from Harpenden, with the layout developed around your garden, privacy and access rather than a fixed building size.

More room
for your everyday.

Explore a room in detail, from the first layout choices to relevant projects and local considerations.

Your Barnet garden

Balance outlook and privacy.

Mark where your room faces the house, a neighbouring window or a boundary. Larger glazing is not always the best answer: a carefully placed opening can bring daylight to a desk or training area while leaving a useful wall for storage.

We also discuss projects in and around High Barnet, New Barnet, East Barnet, Arkley, Whetstone, Totteridge. Share your postcode to confirm the property and access details.

Planning in Barnet

Confirm the permissions for your property.

Use Barnet Council’s planning guidance to check the route for your proposal. Give the exact address, intended use, footprint and height, and identify any conservation, listed-building or other restrictions before treating a garden building as permitted development.

Barnet council: Do I need planning permission?

Your intended use, dimensions and exact address need to be considered together. Planning permission and building regulations are separate checks.
