Construction
The 12mm tongue and groove cladding is fitted to a hefty 50mm squared frame for a durable, long-lasting structure, finished with a smooth-planed surface for a neat appearance in any garden. Standard supply is dip-treated timber, with the option to upgrade to pressure-treated wood and complimentary 15mm cladding for extra protection.
Treatment & Guarantee
Dip-treated timber comes with a 1-year parts guarantee and needs re-treatment within six weeks of assembly and annually thereafter. The pressure-treated timber upgrade includes a 15-year anti-rot guarantee with no re-treatment required, plus free 15mm cladding, though waterproofing is still needed within a month of assembly and annually after.
Doors & Windows
Double doors at the front, 6’2 x 7ft, provide excellent access for vehicles and machinery, while a personal access door at the rear allows entry without opening the main doors. All doors are ledged, braced and fitted with zinc fittings and rim locks. Three windows, one of which opens, provide abundant natural light.
