FORZA 4M x 3M
£18,950 + VAT
The FORZA is our most popular garden room, offering a well-balanced 4m x 3m layout designed for comfortable, year-round use. With generous internal space that suits a wide range of needs, it’s an ideal choice for a garden office, studio, or flexible multi-purpose room that feels open without overwhelming the garden.
Large double-glazed doors and windows bring in natural light and create a strong connection to the outdoors, while full insulation throughout ensures consistent comfort in every season.
Your Versatile Space
With just under 12 square metres of internal floor space, the FORZA offers generous room for a wide range of uses while still sitting comfortably within the garden.
It works particularly well as a garden office, treatment room, studio, workshop, or creative space, but the layout is intentionally flexible, allowing you to adapt the cabin around how you want to use it, rather than the other way around.
Fully insulated throughout the floor, walls, and roof, FORZA is designed for comfortable, year-round use in every season.
A horizontal window comes as standard to bring in natural light, with the option to add a floor-to-ceiling vertical side window if you’d like to increase light further or tailor the layout to your space.
Every aspect of the FORZA garden room is carefully considered, from its proportions to the materials and finishes used throughout.
Large double-glazed openings at the front of the cabin allow natural light to flow into the space, creating a bright and welcoming interior with a strong connection to the outdoors. A fixed double-glazed window complements this, helping to balance light, privacy, and usability.
Subtle matte black spotlights come as standard, providing practical illumination while maintaining a clean, contemporary interior finish suitable for both work and relaxation.
Externally, FORZA is finished in Thermowood cladding, selected for its durability, stability, and attractive natural grain. Over time, the timber weathers naturally, allowing the cabin to sit comfortably within its surroundings.
The result is a well-resolved garden room where quality, comfort, and design work seamlessly together.
Attention to Detail
A Multitude of Uses
The FORZA garden room is designed to support a wide range of uses, allowing you to shape the space around how you want to live and work.
Our to-scale layout drawings show one possible configuration, combining a practical garden office with a relaxed seating area. These illustrations are intended to help visualise how the internal space can be arranged, rather than define how it must be used.
Whether you’re creating a focused workspace, a calm retreat, or a flexible room that balances work and relaxation, FORZA offers the adaptability to suit your needs, now and as they evolve over time.
