The Woodman’s Treehouse in Dorset is a private and unique retreat set high up in the branches of a veteran oak. A combination of sustainable craftsmanship and luxurious interiors, the two level treehouse offers uninterrupted vistas through the tree canopy across the magical Dorset woodland. The project has created a huge amount of media attention in Britain.

Luxury get-away in the tree tops

The grand pier-like boardwalk of the Woodsman’s Treehouse extends into your own private kingdom: a king-sized bed, a double-ended copper bath and the rotating fireplace that can be positioned toward the bed, sofa or kitchen. A particularly notable feature is a window in the floor, looking down to the stream below. The thick insulating walls feature picture windows that offer woodland views, and there is a ceiling window above the bed that looks up at the impressive oak canopy above. No practicalities have been overlooked either: the treehouse has a proper indoor flushing loo and an entrance porch for coats and muddy boots. Outside on the huge rear deck there is a wood-fired pizza oven and barbeque, as well as one of the outdoor tree showers – supplied with endless piping-hot water. It’s ideal in the rain or snow. From this level a spiral staircase leads up to the roof/spa deck, where one finds a hot tub and a sauna offering complete privacy. 

It’s a very special experience to be relaxing up amongst the branches, looking through the woods towards the sunset.

An unique experience installing Sarnafil single-ply roofing membrane on a tree house

It proved to be a special moment for the Axminster-based Roof Assured by Sarnafil installer, Climax Windows, when they were invited to install the single-ply roofing membrane on the flat roof deck of the treehouse. Brian Deem, Managing Director, and his team worked directly with visionary treehouse owner Guy Mallinson and his architect to install 60 mof lead-grey Sarnafil membrane on the decking surrounding the jacuzzi area. The flexibility of the mechanically fixed membrane was perfect for this project, which involved some complex detailing and upstands around the deck railings.

Once the membrane was installed, it was covered with timber decking to continue the natural woodland feel. 

The treehouse is a private kingdom

Owner Guy Mallinson was keen to use local contractors for this undertaking and  chose Climax Windows for their proximity and because they are registered installers  of the high performance Sarnafil membrane. Quality, craftsmanship and aesthetics  were an important feature of this design.

Roofing installers are used to working at heights but in this instance they were literally in the trees working alongside other installers on what can only be described as a unique project. Climax Windows has been a Roof Assured by Sarnafil registered installer for many years and this is the first time they have installed the membrane on a treehouse.

"This was a fantastic project. There was a real sense of working on something special and implementing owner Guy Mallinson’s vision of a magical, luxurious treehouse. The Sarnafil membrane fulfilled all the performance and environmental credentials needed for this project.In all roofing installations correct detailing is critical and there is true craftsmanship in completing complex flat roof detailing and upstands.
