The Willow 5.0 x 4.0m Log Cabin is one of our most sought-after models for those seeking a substantial, "room-sized" garden extension. With a generous 20 square metres of internal floor space, the Willow perfectly balances a large internal volume with a footprint that fits comfortably into most medium-to-large UK gardens. Its classic apex roof and symmetrical frontage, featuring wide double doors and large flanking windows—create a bright, airy, and professional atmosphere. Whether you need a high-end executive workspace or a family leisure retreat, the Willow provides a permanent, solid feel that enhances your lifestyle and property value.

Built from 44mm premium Nordic spruce, the Willow is designed for year-round use. The thick interlocking logs offer excellent natural insulation and structural mass, ensuring the building remains quiet and temperate through all four seasons. This model is delivered as a precision-engineered log cabin kit, specifically tailored for the self-build enthusiast. By taking the DIY approach, you can achieve a professional-standard garden room while avoiding the high costs of specialist contractors.

To ensure your Willow remains a durable fixture for years to come, we recommend a solid, level base as detailed in our base requirements guide. The Willow’s dimensions are intelligently considered to often fall within standard UK planning permission guidelines.
