Sky den was designed by George Clarke and William Hardie as part of Channel 4’s George Clarke’s Amazing Spaces.

Sitting high in the trees, Sky den is composed of three different shapes – cube, cylinder and prism - that each blend together the best of outdoors and indoors, taking in everything from the red squirrels in the trees to the sweeping river below. 

The cube is the main living space, with glass doors opening onto a wide balcony with captivating views over the river. Inside it is an impressively versatile space, with a functional kitchen and entertaining fold-away furniture and beds. A wet room is accessible from the deck. The cylinder is a simple viewpoint of corrugated galvanised steel, where you can have a picnic and brew up a cuppa way over a wood-burning stove. Finally the prism is the loft space accessed by steps from the outside deck, from where it's possible to open the whole roof for an unobstructed view of Northumberland’s dark skies.
