Bedded into the hillside high above the vibrant village of Ullapool on the north-west coast these two turf-topped curvaceous stone hideaways have architectural wow factor. Treetop, perched on the edge of a gorge, sleeps four with panoramic views over native woodland to the sea and mountains beyond through the vast picture windows. Curved Stone House also has fabulous views and a large terrace looking westwards towards the Summer Isles.
