Our Avon log cabins include many features which you'll struggle to find anywhere else! From a tall walkthrough height of 6'2" and high internal eaves to wide opening French doors. If that's not enough, we also include an industry-leading 4-point locking system and additional shootbolt locking.

Let's not forget the pressure treated floor bearers with a 10-year guarantee. Or, the thick 19mm roof and floorboards which are included as standard. Not an optional extra like some competitors. Did we mention the 4mm toughened glass yet? We don't use styrene, Perspex or weak 3mm horticultural glass.
