Luxury Gym and Sauna Garden Room | Balham, South West London

We’re proud to showcase this exceptional 24sqm Modern Range garden room, recently completed in Balham. Designed as a premium home wellness space, this bespoke garden building combines a fully equipped gym, luxurious sauna, and contemporary wet room, giving the homeowners everything they need to prioritise their health and wellbeing without leaving home.
Blending sleek architecture with innovative design features and premium materials, this project is a perfect example of how a garden room can become so much more than an additional space; it can transform your lifestyle.
A 24sqm Modern Range Garden Room
At 24sqm, this bespoke garden room offers generous internal space while maintaining a clean, contemporary footprint within the garden. Designed as part of our Modern Range, the building features minimalist styling, high-quality finishes and a practical layout that allows multiple wellness zones to coexist under one roof. The spacious design comfortably accommodates a dedicated gym, luxurious sauna and fully functional wet room, creating a complete home wellness retreat just steps from the house.
A Bespoke Home Gym, Sauna and Wet Room
Inside, the garden room has been designed to create the ultimate home wellness experience. The gym area provides ample room for strength and cardio equipment, giving the homeowners the flexibility to exercise whenever it suits them. Adjacent to the gym is a luxurious sauna, offering the perfect place to relax and recover after a workout. Completing the layout is a contemporary wet room, allowing users to shower and refresh without needing to return to the main house. Together, these three spaces create a fully self-contained wellness suite that rivals many commercial health clubs.
Contemporary Design with a 500mm Roof Overhang
A defining feature of this project is the 500mm roof overhang, which extends across the front elevation to create a bold architectural statement. The overhang adds depth and definition to the building while offering practical protection from the weather around the entrance.
Combined with the crisp lines of the Modern Range, it gives the garden room a sleek and sophisticated appearance that complements the contemporary landscaping.


Horizontal Cedar Cladding with a Living Sedum Roof
The exterior is finished in horizontal cedar cladding, bringing natural warmth and texture to the contemporary design. The rich cedar tones soften the modern architecture while allowing the building to blend beautifully into its garden surroundings. Above, a striking sedum roof provides both visual appeal and environmental benefits. The living roof helps support biodiversity, improves rainwater management and enhances thermal performance, while creating a seamless connection between the garden room and the surrounding landscape.
Hidden Aluminium Door for a Seamless Finish
One of the most distinctive features of this project is the secret aluminium door on the rear elevation. Cleverly concealed within the wall panelling, the door sits flush with the exterior cladding, creating an uninterrupted façade and preserving the building’s clean architectural lines. This hidden access point demonstrates the attention to detail that defines every Hawksbeck Garden Rooms project, combining innovative design with everyday functionality.
A Luxury Garden Wellness Retreat
This Balham project demonstrates how a bespoke garden room can completely redefine the way homeowners use their outdoor space. By combining premium materials, contemporary architecture, and innovative features such as a hidden aluminium door and sedum roof, we’ve created a truly unique building that is as practical as it is beautiful.
