It’s the ultimate home extension.
A couple have turned their small flat into a £2m duplex by adding an entire extra floor with a crane.
Instead of bringing in bricklayers and builders to construct the extension on the top of their roof apartment for months, the owners had the new prefabricated section of their living space added Lego style.
The original apartment had a cramped living room, a galley kitchen, a main bedroom and a small spare room.
But the crane has dropped double the living space into their lives.
Planning permission for the property in Marylebone in London was granted in 2014 after initially being refused the previous year.
The result is a 1,219 sq/ft flat which is now worth £2 million.
Craig Moffat, of Craig Moffat Architects, advised the owners on planning the project, which took just six weeks.
It took two weeks to erect scaffolding, another two weeks to demolish the old roof and a final two weeks to install the new living spaces.
Four modules were prefabricated by Moduloft in Yorkshire then transported to London, before being lifted on to the top of the building by a six-storey high crane.
The owners have put the flat on the market for £1,995,000 with Rokstone estate agents.
Becky Fatemi, managing director of Rokstone, said: “This superb duplex is the result of an ingenious ‘Grand Designs’ style remodeling which has replaced a small single level flat with a stunning loft-style duplex apartment.
“The owners have liaised with architects, planners and a modular construction specialist in order to create their dream London home.
“The makeover has effectively doubled the size of the apartment and created a brand new home on the roof of an existing period building.”
