Chelsea roofs are constructed from Western Red Cedar shingles with elegantly cambered eaves. Shingles are cut to size by hand and are laid in a roof specific pattern to avoid water penetration. Internally the roof is left unlined with braced battons. (The roof is lined with plywood when upgraded to a fully insulated building).


Chelsea summerhouse sides are constructed and externally clad with Western Red Cedar shiplap panel boards and are lined internally with either plain or tongue and groove moisture resistant MDF or hardwood veneer plywood. All buildings have the option of having insulation as an upgrade, with the exception of the Sunbury gazebo.


Flooring within all summerhouses have integral tongue and grooved flooring laid onto traditional preservative treated floor joists, with the exception of The Sunbury that is supplied with a slatted floor.


Chelsea Summerhouse doors on all models are constructed in cedar using traditional mortice and tenon joinery. All our timbers are ethically sourced and are PEFC certified.


Traditional hand leaded lights, made from individual panes of glass are standard. An upgrade to double glazing is also available, with a plant-on lead or plain glass option. Windows are side hung.

Full Height Glazing

We also offer the option of full height glazing enabling you to have panoramic views of your garden. This would be toughened double plain glazing.

Base Works

For peace of mind and many years trouble free use, we recommend a concrete base or a hard standing such as a paved area to sit your summerhouse on. Full and comprehensive base plans will be supplied when your order has been placed.


All buildings have the option of having insulation as an upgrade, with the exception of the Sunbury gazebo. Foil backed insulation is used to insulate the floors, sides and roof.


An electrical pack is available, which consists of two double sockets, a ceiling light and external consumer box.


All door and window furniture is brass as standard with the option of pewter or black.


An exclusively designed storage feature within the summerhouse boarded panels, shelving is available as an optional extra. The shelving allows drinks, glasses, books or even a radio to be within easy reach and can be incorporated within any of the summerhouse models.

Box Seating

This clever sectional style of seating offers the best use of interior space, for any Chelsea Summerhouse as it also doubles up as integral storage space. It comes complete with deep foam padded seats and loose back-rest cushions in a range fabrics.  All seating is painted to match your summerhouse so that it blends in perfectly.
