Made for life
in Harpenden.
The completed 5 × 5 m gym in Harpenden shows why headroom belongs in the first conversation. That project used planning permission for its internal ceiling height. Bring your equipment list and preferred exercises to the design discussion, then compare a dedicated training room with a layout that keeps a smaller area for recovery.
Start with what mattersGood design
Good design
begins here.
Three conversations to have before settling on the size and specification of your garden gym.
01
Equipment first
Share the exact models, weights and working clearances for racks, treadmills and benches. A floor area alone cannot confirm that equipment fits.
02
Headroom and floor design
Internal ceiling height, lifting movements and equipment loads need to be checked together with the building structure.
03
Sound and fresh air
Discuss ventilation, impact noise and the position of openings in relation to neighbouring homes.

Do you build garden gyms in Harpenden?
Yes. Harpenden 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.
Will a standard garden room height work for my gym?
That depends on your height, equipment and movements. Internal headroom is less than the external building height. Cedar’s 5 × 5 m Harpenden gym used planning permission to achieve its documented 2.5 m internal ceiling; your own design needs a separate assessment.
What should I check about planning in Harpenden?
Harpenden includes a conservation area, and the district also has address-specific Article 4 restrictions. Check the council’s maps and the exact controls applying to your property before settling the position and appearance of a building. Ask St Albans City and District 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.
