20ft (6.10m) Wide

In these 20ft wide models, potential features are thoughtfully incorporated to cater to various preferences. Depending on the model, there might be guarantees of 10, 15, or 25 years, offering peace of mind regarding the longevity and quality of your summerhouse. Single or double French doors add a touch of elegance and provide easy access. In contrast, the choice between single or double-glazing ensures your summerhouse is well-lit and comfortable throughout the year. High-quality shiplap tongue and groove boards might be used in construction, ensuring durability and a refined finish, and dip-treated timber could extend the life of these structures.

Roof designs might vary between apex or pent, with options for insulated or non-insulated roofs to suit different needs. Some models' use of environmentally friendly FSC-certified timber underlines a commitment to sustainability. These 20ft wide summer houses are not just an addition to your garden; they are a statement of luxury, versatility, and environmental consciousness, enhancing your outdoor living experience in countless ways.
