A Tribeca apartment designed by James Ramsey, the brains behind New York’s Lowline, is now available to rent.

The property at 151 Hudson Street, a 1910 structure, features a custom-made bookcase that hides a secret door leading into a bedroom. It also retains many of its pre-war details, including wooden ceiling beams and exposed brickwork.

‘I love the idea that you can have secrets and find discoveries in a space – the secret bookcase door was just me having fun,’ says Ramsey. ‘Even just the thought that something like that exists makes people wonder if there are other things they haven’t found yet, so it makes for a level of intellectual engagement with a space that makes it more special.’

Ramsey, the principal of Raad Studio, has worked on several Manhattan apartments but is best known for his Lowline proposal to convert a disused trolley terminal into an underground park.

He launched the Lowline Lab last year in New York’s former Essex Street Market building as a test bed for the subterranean scheme.

The two-bedroom apartment at 151 Hudson Street is available via Douglas Elliman for $14,000 a month.
