Napoleon-proof your home: convert a Martello tower

Britain's Martello towers were built to keep the French navy at bay.
Jonathan Glancey reports on how one rotting relic in Suffolk was turned
into an extraordinary new home.
Martello towers were built, at great cost, along the coasts of Kent,
Sussex, Essex and Suffolk at the time of the Napoleonic wars.
Originally, there were 103 of these 30ft-high towers, with walls 13ft
thick and roof-mounted cannons capable of shooting lead balls a mile out
to sea.Duncan Jackson's Martello tower, rising from behind the
seawall at Bawdsey in Suffolk, is a daunting structure, yet it has been
reworked to provide a warm and unexpected welcome: warm because the
thick walls keep the winter at bay; and unexpected because, inside,
industrial designer Jackson has shaped one of the most original and
soul-stirring modern homes in Britain – from a neglected fort never
designed for comfort.

I've seen some of those towers and I've seen the one converted into a home.
There was a tv documentary on it following the conversion from start to finish.
Amazing!
