For a modern, multipurpose garden building, suitable for use the whole year round, choose the Mercia Helios 4m x 3m Curved Roof Log Cabin (44mm) - Double Glazed. A British-Built Log Cabin Expertly built in Great Britain, from 44mm interlocking logs, this garden cabin is robust, durable and incredibly well insulated. Both the floor and roof are constructed from 16mm tongue and groove, so they’re strong, stylish and supremely weathertight. The roof features an eye-catching curved design and is fitted with a premium mineral felt cover, so you’ll enjoy complete weatherproof protection. The wood used to build this stylish log cabin is FSC® certified, which is the world’s most trusted mark for sustainable forestry. Double Doors and Opening Windows You can gain easy access to the garden room via glazed double doors, which include adjustable hinges, a chrome handle, and key-operated lock to keep your valuables secure. Thanks to 3 additional large windows, this log cabin enjoys an abundance of natural light. All of these windows are openers, so you can ventilate the interior, whenever you desire. The glass used is 14mm double glazing, providing increased insulation and better soundproofing. Installation, Treatment and Guarantees This log cabin should be installed on a firm, level base. The wood is supplied untreated and must be coated in a high-quality preservative and waterproofing treatment upon assembly, and annually thereafter. This will protect it from rot, validate the impressive 10-year anti-rot guarantee, and maintain the log cabin’s attractive appearance. Alternatively, why not paint your new garden cabin for a more individual look? A 1-year parts guarantee is also included. Available Sizes and Optional Upgrades You can purchase this log cabin in 2 different sizes.
