Martello Tower Y

Martello Tower Y

This award-winning conversion of a dilapidated Napoleonic sea defence tower into a contemporary home is highly respectful of both heritage and setting. A Scheduled Monument in an Area of Outstanding Beauty, it took a committed multi-disciplinary team to ensure that the design vision remained intact throughout two years of complex planning negotiations.

The existing fabric, geometry, and form were key design drivers. A new lightweight curving roof extension of steel and plywood, prefabricated off-site using computer generated cutting patterns, is lightly tethered to the existing structure and set back to minimize visual impact. A deep curved skirt of frameless glass floats between old and new and provides stunning 360-degree views of the coastal landscape from within.

The curving roof extension is not only sensitive to the monument and it’s setting, it echoes the sculptural interior of vaulted brickwork creating a congruency between contemporary and historic.
