Bespoke Garden Gyms from £12,959

Fully customisable garden gyms, bespoke outdoor fitness studios, and external home exercise rooms with fast nationwide installation. Made to order from durable all-weather materials, our collection of modern garden gyms come with a 10-year guarantee.

Whether you’re doing an intense workout with weights and cardio or stretching and strength building with yoga and pilates, a modern garden gym will give you a space to train without distraction – all year round.

Our modern garden gyms are the perfect alternative to sacrificing a room within your home or choosing an expensive and messy extension. Depending on the size and design of your bespoke exercise studio, we can typically have your modern garden gym fabricated, installed and up-and-running in just one to three weeks. We begin with a detailed site survey to understand your requirements and assess the possibilities available within the space you have. With this information, our team can bring your vision to life and design a bespoke outdoor gym that smashes your goals. Fully customisable, insulated, heated, and powered, a modern garden gym is a fast, flexible solution to working out at home.

Choosing your
Modern Garden Gym

Garden Gym Planning Permission

Install a bespoke workout space in the peace and tranquillity of your garden, without the need for planning permission.

Our modern garden gyms have been specifically engineered to meet Planning Permission criteria for external buildings added to your property. In most circumstances, your bespoke garden gym can be erected without needing to make a planning application. Our collection of garden gyms are designed to take up 50% or less of your total garden area, and the structures are no higher than 2.5m from the bottom of the building to the top of the roof to comply with planning permission guidelines. This makes the installation process straightforward and easy to navigate. Without the time and cost of the planning application and approval process, you could be working out in your new garden gym in as little as three weeks.

Get active in your garden

Our collection of garden gym designs offer the perfect space to get active outdoors, all year round – rain or shine.

Equipped with everything you need for comfort and fully customisable to meet your exact requirements, our garden gyms are warm and weather resistant. With energy-efficient insulation and built-in heating, lighting and power, your outdoor gym can easily be adapted for use as a multi-purpose space – for example, a garden office-come exercise studio.

If you’re tired of working out in the living room, sacrificing space in your home office, or tripping over the treadmill, then it’s time to upgrade your workout space to a dedicated home exercise studio. A modern garden gym is a great solution for those who don’t have room to spare. A bespoke garden gym gives you the dedicated space you need to take your training to the next level. We design your garden gym to your exact specification and customise the size, shape, fixtures, fittings, and furnishings to suit your taste.
