The Windsor Hexagonal Summerhouse

The Windsor is a hexagonal shaped, traditionally designed, western red cedar summerhouse and the perfect addition for any sized garden. This superior quality summerhouse provides an idyllic hideaway to escape the interruptions of everyday life, and the perfect retreat to enjoy the changing seasons.

Handcrafted by skilled carpenters, this British made summerhouse, features a Cedar shingle roof that is made to last. Cedar is renowned for its resistance to the effects of rain, sun, pests and time, making it the ideal choice for a long lasting look of beauty.

The Windsor has 2 opening casement windows and a set of double doors with leaded glass.  All doors are constructed in Western Red Cedar using traditional mortice & tennon joinery. A double glazing upgrade is available in either plain glass or plant-on real lead.

This luxury Summerhouse, comes with solid brass fittings and a high cedar shingle roof, with elegantly cambered eaves.  Internally the exposed battens and cedar shingles create a stunning traditional feature.  The interior walls benefit from a lined interior giving a clean finish. A tongue & groove floor comes as standard and an insulation upgrade is offered for those wishing to use their summerhouse all year round.

Chelsea Summerhouses are offered with a market leading 10 year guarantee and all timber used in manufacture is sourced from managed forestry.  All buildings are available installed.
