The André Balazs website is still without any mention of the hotel, but taking the name of Knight Harwood (the contractor for the site) to the internet, we found some interesting bits of information and... renderings!
According to the website, the Grade II listed fire station - which dates back to 1889 - will house just 26 luxury suites. That's an even smaller number of rooms than we had thought. The project is "the vision of Manhattan Loft Corporation who have built schemes such as the St. Pancras Renaissance Hotel in London and André Balazs who developed The Mercer and Chateau Marmont in the USA".
Renderings show exposed brick, lattice-wood on the ceilings, and lots of greenery. We'd venture a guess that the pitched ceiling with the beams is in the smaller structure with the two little turrets that you see in one of the pictures, across the courtyard from the main building that is currently mostly covered in scaffolding.
These little snippets of information only increase our hunger for more details on what André has up his sleeve here. We'll keep you posted as we try and find out more.
