Measuring 4m x 4m, the Creswell offers a versatile solution for those seeking a modern extension for various purposes. Whether it’s a home office, guest accommodation, or simply a retreat to unwind, this all-purpose garden room is designed for year-round use.
Enhanced with Anthracite UPVC doors and windows, the Creswell ensures both aesthetic appeal and practicality. The double-glazed windows not only provide a sleek finish but also contribute to maintaining a comfortable interior temperature throughout the seasons. With upgraded locks on both doors and windows, security is bolstered, offering peace of mind. The UPVC material also extends the longevity of the structure, forming an airtight seal against the elements.
In addition to Anthracite, the Creswell offers UPVC doors and windows in white and oak finishes, providing flexibility to suit various outdoor aesthetics. Alternatively, timber options are also available to cater to individual preferences.
Part of our premium Sherwood range, named after local landmarks, the Creswell boasts premium features as standard. Eco-quilt multi-foil insulation lines the walls, roof, and floor, offering the equivalent insulation of 100mm glass wool. Combined with double-glazed windows and French doors, this ensures a cozy interior regardless of external conditions. The walls feature a double-skinned design with easily removable internal panels, facilitating the installation of electrical components—a perfect solution for organizing office cables. Furthermore, the roof is topped with a durable waterproof rubber membrane designed to last for 50 years.
Externally, the Creswell boasts a modern design with elegant architectural features. The recessed front aspect not only adds visual appeal but also provides a sheltered entrance and veranda—ideal for rainy days. The open-plan interior creates a bright and airy atmosphere, suitable for various activities, from work to relaxation.
Customization options abound with the Creswell, from additional windows to door relocation. Manufactured to order in the UK by our skilled team using top-grade materials, quality is assured.
