Piercy Connor Architects has won planning permission for this conversion of a Napoleonic sea defence tower. The scheme will convert the Martello Tower Y on the Suffolk coast into a private dwelling.The 200-year-old scheduled monument stands in an Area of Outstanding Natural Beauty and is currently on the Buildings At Risk Register. The project will float a new roof above the existing historic fabric, which will undergo extensive restoration. A continuous 700mm-deep skirt of perimeter glazing below the roof will provide a 360-degree view of the landscape and sea. The project is due for completion in November.
