Your equipment, your routine, your own space to move. Design a training room with the floor, headroom and ventilation your workouts need. Designed and built for your Enfield garden by our Harpenden-based team.

An Enfield gym should suit the routine you can keep using all year. Plan a place for shoes, towels and smaller equipment so the training floor stays clear. Tell us about early sessions, ventilation needs and the largest equipment item; those details help place doors and windows before you settle on a building size.
Three conversations to have before settling on the size and specification of your garden gym.
Share the exact models, weights and working clearances for racks, treadmills and benches. A floor area alone cannot confirm that equipment fits.
Internal ceiling height, lifting movements and equipment loads need to be checked together with the building structure.
Discuss ventilation, impact noise and the position of openings in relation to neighbouring homes.

This 5m x 5m bespoke garden gym in Harpenden brings the full fitness experience home. Finished in timeless cedar cladding, the interior features high-end gym equipment, a mirrored wall, and durable flooring — everything needed for strength, cardio, and functional training. Built with planning permission to achieve a 2.5m internal ceiling height, the space feels light, open, and professional. A stunning setup for maintaining fitness and wellbeing without leaving your property.

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.
