This large playhouse was designed to function as an outdoor classroom. The classroom sits on a platform which is accessed via a small staircase which leads up to a veranda.  There are double doors on the front which allow good access and can be opened up when the weather is worth enjoying.  Either side of the door there is a large window to allow plenty of light into the classroom.  On the right hand side there are 3 double casement windows. The central casement is double opening and then then other 2 have 1 casement opening.

Specification

Your playhouse comes with a solid floor, it is constructed using 25mm x 50mmm tanolised bearers supporting an 18mm wbp external grade plywood floor: this is treated on the upper side using sadolin classic timber protection. Sandwiched between the bearers and plywood is a damp proof membrane that then wraps around the edge and sits under the playhouse side. The membrane is there to stop moisture coming up.  A soft floor is fitted to the ground floor of the playhouse once finished - this floor can be removed easily for cleaning.  This is then sited on to a decking platform.

The playhouse roof is built to withstand the English climate; 75mm x 50mm bearers are put across from side to side. Screwed to these bearers is 12mm external quality plywood covered with a base layer of waterproof membrane and then a top layer of 38kg mineral felt, using stainless steel staples. The felt is wrapped over the front and back and sealed behind the facia board.

The windows are built as separate units; once they have been sanded and treated they are glazed and then fitted and sealed using clear silicon into the frame. These windows are glazed with 2mm polycarbonate sheet, this is completely clear, will not fade or become brittle with time, it is 200 times the strength of glass making it virtually shatter proof. The opening window is hinged on either the right of left using a stainless steel piano hinge and our special non trap design. When the window is in the closed position there is a taper between the casement and frame so should any little fingers be in the way they will not get pinched. The casements are held using a brass handle and casement stay.

This is our highest level of build, the playhouse will have a damp proof membrane in the walls, full insulation and flat plywood lined walls on the inside with architrave around the doors and windows and skirting board around the bottom of the walls.

Initially a framework is built using 50mm x 38mm timber. To this we fix on the outside a weatherproof membrane and good quality redwood ship lap using galvanised brads, insulation panels are fitted between the framework before 6mmwbp plywood in fitted as an internal skin, this makes the side panels. Architrave is fitted around the doors and windows and skirting around the bottom of the walls. These panels are then sanded and treated on the outside using two coats of Sadolin wood preservative. These are then fitted together on site, a clear silicon seal is applied to all the corners.

• Mineral Felt

  High quality 38kg mineral felt over the top of base felt.

• Felt Shingles

  To give the appearance of tiles, these go over the base layer of felt.

• Cedar Shingles

  Traditional roof finish in North America, Cedar shingles are fitted over the top to the felt.

• Option 2

  All of option 1 with the addition of 6mm wbp plywood and a damp proof membrane between the frame work and the shiplap. The floor is 18mm wbp plywood with a damp proof membrane on tanolised bearers.

• Option 3

  All of option 2 with the addition of fitted insulation. The insulation fits within the frame and the plywood is attached to the inside giving a flat surface throughout the walls. The windows and doors are finished with architrave and skirting is fitted around the bottom. The floor is 18mm wbp plywood with a damp proof membrane on tanolised bearers.
