Our Range of Customisable Garden Gym Buildings

We sell garden rooms in a range of designs, which can be used for many specific uses, like garden offices, art studios, or garden gyms. Our “Contemporary” design is ideal for a garden gym room, helping you to create a beautiful exercise space within your garden.

The dimensions of your home gym can be either be small enough to fit a running machine and training mat, or large enough to fit several pieces of gym equipment and a weight bench. Our standard garden gym room sizes can go up to 6.2m x 4.2m, offering a huge garden space. Structurally, the height can also be adjusted, and you’ll have the option to install an internal wall in larger buildings.

You can choose from our selection of quality UPVC window options, featuring everything from longer screen windows to smaller vent windows, which can offer airflow whilst maintaining privacy. Windows can be installed wherever required in your garden room, allowing you to prioritise natural light, or give yourself privacy from certain angles.

Aesthetically, you’ll be able to choose the colour of your UPVC windows and doors, the type of internal and external wall cladding, and the type of laminate flooring installed. Our garden rooms come with insulation, internal spotlights, and electrical sockets as standard.

How to Utilise Your Home Gym

A garden gym room can be tailored to meet your exercise needs, making a beautiful extra space outside your property. Whether looking for a high cardio workout featuring a treadmill, an exercise bike, and a rowing machine, or a weight room with a bench, a squat rack, and a dumbbell stand, we can build you an ideal home gym. Having a quality exercise area within your property will allow you to stay fit around the busiest of schedules, whilst maximising comfort and privacy.

How can I order a garden room in a different size than those listed?

The sizes provided are shown as guidelines for our customers, and we are able to produce our designs in other bespoke dimensions. Simply email us with your desired bespoke measurements and we will be able to give you a quote.

Do I need groundwork for my garden room?

Our Garden Rooms can either be installed on to a concrete or paving slab base (customer to organise with a local contractor). Alternatively, if you are within our standard radius, then we are able to offer the option of a ground-screw base, with timber frame. (Please note, ground-screws are only available on selected models).

Will I need planning permission to build a garden room?

In the majority of cases planning permission will not be needed to install a garden room. If looking to build within 2m of the boundary around your garden, you will have to opt for our default 2.5m height. In some select cases, such as when your house is a listed building, or when your garden borders an area of outstanding natural beauty, you may need to apply for planning permission. We recommend contacting your local building authority with any concerns you may have about building a garden room.

If you require planning permission, you will need a local planning consultant or architect to prepare the drawings required for a planning application. We can provide the information for you to allow the drawings to be produced. You can then either submit the application yourself or employ someone to do so on your behalf.

Is my garden room/office suitable for year round use?

The Garden Rooms and Offices are fully insulated for year round use. They are designed to be warm in the winter and cool in the summer, however the location in your garden will have an impact on how warm / cool the building is.

North faced gardens will have buildings that are naturally cooler throughout the year, whilst south facing garden will be naturally warmer throughout the year.

A building in the shade or in a north faced garden, will need a small heater during the winter months, but will remain cosy when the building is up to temperature.

A building in direct sunlight or in a south facing garden will benefit from more ventilation and blinds between the glass to keep the building cooler.

How long will my building take to build on site?

Garden Rooms are usually constructed within 1-2 days (up to 6.2m x 3.6m sizes) depending on the final specifications.

Garages up to 6.1m x 6.1m are usually constructed within 1 day. Larger buildings will often take 2 days on site.

Commercial Buildings usually take 1 week on site – depending on the final specification.

What is the lead time?

The lead time for a building can vary between 2 – 6 months.

You are welcome to book in advance to secure a delivery slot, and still make adjustments to the design up to the point that the base has been constructed.
(Please note that items that have been specifically order for you will still need to be paid for)

Please explain the electrics?

Garden Rooms and Offices include the first fix wiring, along with the consumer unit, lighting and the faceplates.

All wiring is installed within the cavity and is ready for an electrician to connect the tail ends of the wiring at the consumer unit and the faceplates.

The electrician will need to provide and install a power feed from your house / garage to the new building – usually a 6mm armoured cable is used. The wiring provided is 1.5mm cables for lighting on a 6 Amp fused circuit, and 2.5mm cables with a 32 Amp breaker for the sockets – on a ring main.
There is space for a 3rd breaker if it is required for another feed.

It usually takes half a day for the internal connections, plus the time required for the electrician to install the cable that you require.

Our electrician can offer customers in Warwickshire and Worcestershire with installation and certification independently – please contact him directly (Andy Punnett) via his website If you live in Berkshire or Hampshire, please contact Ben Thorp on 07917 131984

What maintenance is required?

The weather, location and the sun can all have an effect on buildings, however throughout our 35 years we understand how our product works and how it stands up to the test of time.

Your maintenance schedule should be:

  • To clean the gutters out to keep free from debris
  • Adjust doors and windows that have expanded or contracted through weather conditions
  • Remove debris from the roof
  • Treat the outside of the building as required to maintain an attractive appearance. (This provides a waterproof coat to the timber and keeps the moisture content of the wood consistent – which in turn improves the stability of the timber, and reduces the expansion & contraction of the timber)

Our guarantee is in respect of design and manufacturing faults, corrosion and rot for 10 years from the date of installation.
