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 Barnet garden by our Harpenden-based team.

For a Barnet golf studio, first establish the simulator’s clearances and where the screen can sit without compromising the swing area. Then consider impact noise and glare in relation to neighbouring homes. Our completed St Albans studio shows a bespoke solution with planning permission; the same dimensions will need their own assessment in Barnet.
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.
