The Henley Summerhouse

The Henley offers a large and airy outdoor room for entertaining or as a garden office or studio.  Rectangular in design, this beautifully proportioned  summerhouse is constructed from Western Red Cedar, and offers endless possibilities as a substantial garden living space.

Handcrafted by skilled carpenters, this British made summerhouse, is constructed from the finest Western red cedar and features a stunning cedar shingle roof.  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 Henley comes with 2 opening windows to the front elevation, one set of opening windows to the side, a set of fixed windows to the side, plus a set of double doors all with leaded glass.  All doors are constructed from Western red cedar using traditional mortice & tennon joinery. A double glazing upgrade is available in either plain glass or with plant-on lead.  Alternatively, choose long fixed windows for a more contemporary feel (see pictures).

This luxury Summerhouse, has solid brass fittings and a high cedar shingle roof, with elegantly cambered eaves.  This beautiful structure benefits 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.

Do I need a base?

Yes, your Summerhouse must be erected onto a level hard standing base, ideally in concrete, smooth paving slabs or decking.  Base plans are available for all summerhouses. Please note that if a base is found to be more than 20mm out of level, the installers may be unable to install.
