I’ve often spotted it on my walk along the towpath from Folly Bridge to Iffley. Across on the east bank of the Isis, nestled into the Kidney Stream, an old cut leading to the Cherwell from the Thames just before you reach Donnington Bridge. A fanciful floating pavilion rising from the water, its curved prow reminiscent of classical longboats, flagpole erect, pilasters framing the door to a whimsical white wooden cabin with hobbit like oval windows. There’s an external staircase leading to a raised rooftop garden overhung with willow, a tall chimney in the middle from which on colder days white plumes of smoke announce that there are occupants below. It all looks very romantic.
