More time for your game. Start with your swing and chosen simulator, then shape a dedicated practice room around your garden. Designed and built for your Harpenden garden by our Harpenden-based team.

For a golf studio in Harpenden, begin with the simulator rather than choosing a building from a photograph. Our completed St Albans golf project is a useful nearby reference for a room designed around practice, cinema and fitness. Confirm the clear swing space and planning route for your Harpenden property before committing to its height.
Three conversations to have before settling on the size and specification of your golf studio.
Check width, depth and clear internal height with your simulator supplier for the actual players and clubs.
Allow for screen stand-off, impact protection, projector position and the tracking requirements of your chosen equipment.
Balance glare control for the screen with daylight, seating and any cinema or fitness use.

This 6m x 4m garden room was designed with a 3m internal ceiling height to accommodate a state-of-the-art golf simulator, creating the perfect environment for year-round practice. Built with planning permission secured, the space also doubles as a home cinema and private gym, making it a truly versatile addition to the property. Finished with premium materials and tailored for multi-use, it blends luxury and functionality in one bespoke Cedar Space.
