Garden Room Directory


Sanctum Garden Studios offers four ranges of buildings ideally suited for use as home gyms. Their designs span a wide range of sizes, starting from a compact 1.8m x 1.8m—among the smallest options on the market—to a generous 9m x 3.5m. For those seeking specific dimensions, Sanctum also provides a bespoke design service.

Sanctum Garden Studios designs each of their ranges as a multi-layered structure, ensuring year-round comfort. This allows you to utilise your garden gym every single day, regardless of the season. For those who wish to set an ideal workout temperature, air conditioning can be added as an option.

Sanctum Garden Studios’ glazing configurations foster a lovely connection with the garden, allowing natural light to flood in and frame views of the garden. There are a range of window styles to choose from, including opening windows so you can easily ventilate the gym room.

Each Sanctum Garden Studio includes the foundation system, so all that is required before the installation team arrives on-site is that the ground be relatively level and free of vegetation. If you have a concrete slab already in place Sanctum can adjust their system to work with this. Sanctum has a streamlined installation process with on-site build times for some ranges being just a day. The gym’s electrics are connected to an external junction box, so all that is required is for you to get a local electrician to run the connection between the house and the gym. Once this is done, your garden gym will be ready to start using.

The Hampton – is designed to provide excellent value for money. It features a glazed front elevation, made up of a mix of a single door and long windows. You can choose where the door is positioned in this configuration and you can swap one of the fixed windows for an opening one. Sanctum offers several options to personalise the Hampton, including adding Western Red Cedar panels to the side elevations. The Hampton comes in three sizes: 2.4m x 2.4m, 3m x 2.4m and 3.6m x 2.4m.

The QuadPod – has a contemporary style enhanced by the mix of Western Red Cedar cladding on the prominent elevations and dark grey weatherboard on the other walls. The QuadPod comes with a choice of two window styles: an office variant with a desk-height window or a studio variant with a tall window. The QuadPod range comes in five popular sizes: Super Micro 1.8m x 1.8m, Micro 2.4m x 1.8m, Mini 2.4m x 2.4m, Maxi 3m x 2.4m and the Super Maxi 3.6m x 2.4m.

The Contemporary – this range offers customers greater flexibility over the size, finishes and configuration of doors and windows. The Contemporary range comes in sizes from 2.4m x 2.4m. Available in two styles – one with a roof overhang and the other with a cubed roofline – these studios allow for customisation of the size and configuration of doors and windows. With its Cedar cladding finish, this range offers the freedom to create a home gym tailored to your individual needs and preferences.

The Urban – the latest addition to the Sanctum Garden Studios range, it features maintenance-free composite cladding available in five colours. Like the Contemporary range, the Urban comes in two roof styles: overhang and cubed.

If you have something unique in mind, Sanctum Garden Studios also offers a bespoke design service. They can incorporate special design features, such as roof canopies and covered seating areas, to meet your specific requirements.

Sanctum Garden Studios’ in-house team travels across the UK to install their buildings.

Examples of Sanctum Garden Studios exterior finishes

Each of the four ranges offered by Sanctum Garden Studios has a unique palette of exterior finishes:

For the Hampton range, the walls are finished with a dark grey engineered wood weatherboard. This board is colour-matched with the uPVC door and window frames for a cohesive look. Customers can choose to add Western Red Cedar panels to one or both side walls. The roof is an insulated steel system that has a dark grey finish externally and a crisp white finish internally.

The QuadPod range offers two walls of Western Red Cedar cladding, while the other walls are finished in dark grey engineered wood weatherboard. Anthracite grey uPVC is used for the door and window frames. The roof is an EPDM system complemented with a shingle covering.

The Contemporary range, as standard, features Western Red Cedar cladding on the front elevation, combined with tanalised Redwood cladding on the other walls. However, customers have the option to swap the Redwood for Cedar on these walls, with clear pricing for this option provided on the website. The door and window frames on the Contemporary range are Anthracite uPVC, with a selection of French and sliding door styles, as well as Aluminium bifold door options to choose from. There are also several window styles on offer. For the Contemporary Overhang variant, the roof is a steel insulated panel, dark grey on the outside and white on the inside. In contrast, the Cubed variant features a maintenance-free EPDM roof with a shingle covering.

Lastly, the Urban range features maintenance-free composite wood exterior cladding. The cladding boards feature a textured wood grain and are available in five different colours. The options for doors, windows, and roofing are the same as those in the Contemporary range.

Examples of Sanctum Garden Studios interior finishes

Sanctum Garden Studios offers different interior finishes across their range of buildings:

The interior of the Hampton and QuadPod ranges feature an MDF lining. This smooth, matt finish can be left bare, or you can paint it in your choice of colour. MDF takes paint well.

The Contemporary and Urban range features a white Melamine interior with neat uPVC strips over the joints. This finish creates a light modern interior and is easy to keep clean. As an optional extra, you can swap the Melamine for plasterboard, which you could then arrange to have skimmed and decorated.

Each Sanctum Garden Studio is pre-wired with electrics, the number of sockets and light fittings is listed on each range page on their website. Additional sockets can be added, and they are clearly priced on their website. The electrics run to a junction box on the exterior of the gym. You would then arrange for a local electrician to run a cable between this junction box and your house.
