With both a 17.3m² and a 5.5m² room; creating a fabulous 22.8m² of space, this high quality garden room is built with 70mm thick logs allowing year round usage of this Palmako Heidi Log Cabin as a guest suite, home office or a myriad of other uses.

Made from high quality Nordic spruce, the 70mm interlocking logs are chalet-cut for improved protection against wind and rain. Further strength and stability is provided by threaded rods (which increase wind protection) for a robust, durable garden cabin. At 70mm, this is one of the thickest logs offered, providing a garden room suitable for year round use. The notch corners add a traditional appeal.

The roof and floor are constructed from 19mm tongue and groove cladding, well-known for its weather resistance, durability and strength - with the floor also being supported by treated foundation joists providing a long-lasting and hardwearing surface for the many years of use this space will receive. The distinctive roof overhang is not only an attractive design feature but also provides practical shade and protection for the front of the log cabin and for you.

The two immense windows and the fully glazed double doors provide extensive light to the main room of the log cabin and offer your excellent views of your garden. A high, privacy window provides light for the side room, ideal as a bedroom. All are double glazed with rubber seals providing enhanced insulation for the garden cabin. The doors also benefit from a stainless steel door sill to protect this high traffic area. For increased strength and improved resistance to adverse reactions to extreme temperatures, such as warping or cracking, the door frames are laminated in construction. A key-operated cylinder lock provides security

A five year guarantee supports the high quality of this garden building. The garden cabin is supplied untreated; we would recommend that an initial anti-fungal treatment is applied and repeated annually thereafter to support the guarantee. Alternatively, paint could be applied to suit your preference or garden design.

The Heidi from Palmako is available as a 20x11 log cabin or a 44mm 10x13 log cabin.

*Please be advised that this garden building is supplied untreated. You should apply a coat of quality wood preservative upon assembly, and annually thereafter, in order to protect the wood from rot and maintain its handsome appearance.*
