The garden will feature terraces and topiary complete with octagonal folly and a sunken Italianate pond. Every 15 minutes, box balls will bob up and down, conical bay trees begin to twirl, and planting will rise from the ground to dress the first-floor windows. A wooden shed houses contraptions created from cogs, wheels, straps and parts of old bicycles which form the garden gadgetry.
