A multi-purpose garden room, consideredMade for life
Made for life
in Barnet.
In a Barnet family room, decide how the space should look from the house after dark as well as during the day. Seating, screens and desk positions can be arranged to preserve privacy while retaining a garden outlook. If you want a toilet or kitchenette, bring that into the initial brief so the layout and service routes are considered together.
Start with what mattersGood design
Good design
begins here.
Three conversations to have before settling on the size and specification of your multi-purpose garden room.
01
Choose the main use
Give the activity you do most enough room. Then test how a desk, sofa, exercise area or games table shares the remaining space.
02
Separate where it matters
A partition can give working calls some privacy; integrated storage can keep the main room useful between activities.
03
Plan services early
Mention a toilet, refreshments area or other plumbing at the start so routes, approvals and costs can be assessed.

6m x 3.5m Leisure Room in St Albans
This 6m x 3.5m garden room in central St Albans is clad in timeless Western Red Cedar, making it a stunning focal point within a newly landscaped garden. Designed as a multi-purpose space, it serves as a TV lounge and chill-out zone while also housing a Wattbike and weights for fitness. Two sets of bi-fold doors flood the room with natural light and open seamlessly onto the garden, creating a bright, flexible space perfect for both relaxation and exercise.

Do you build multi-purpose garden rooms in Barnet?
Yes. Barnet is within Cedar Spaces’ published Hertfordshire and North London service area. Our team is based in Harpenden. Share your postcode and garden details so we can assess access and the scope of your project.
Can a garden room combine an office and a family space?
Yes. Cedar’s project collection includes partitioned offices, leisure rooms and larger multi-use buildings. We can discuss open-plan and separated layouts. Overnight accommodation or a self-contained annexe needs a separate brief and permissions assessment.
What should I check about planning in Barnet?
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. Ask Barnet Council about the requirements for your specific address and proposal.
How do I get an accurate price?
Share your postcode, intended use, approximate dimensions and access details. We then discuss the specification and site requirements. The online studio’s base guide is not a complete installed quotation; Cedar Spaces is VAT registered; ask for a written total with the VAT breakdown, inclusions and exclusions.
Can I see real Cedar Spaces projects?
Yes. Our project collection includes photographs and descriptions of completed buildings, including offices and gyms in Harpenden and leisure and golf rooms in St Albans. Each example shows its actual location.
