Built round a 300-year-old oak the 15ft long, oval-shaped, mid-air "dining room" is reached by a wide spiral staircase that sweeps round the girth of the tree.

There is a 'curvy' bespoke oak table that seats 12, a selection of chairs with cushions and a wicker basket on a pulley to bring up supplies. Although roofed with nicely weathered cedar shingles, the sides are open to the elements, giving the structure a light airy feel and affording wonderful views, particularly in the evenings.
