The property, which is being marketed as an “urban resort”, is located on the banks of Lake Alster around 10 minutes’ walk from the centre of the northern German city.
The Fontenay has been designed by local architect Jan Stormer and features 130 rooms and suites – the majority of which will include a balcony.
The hotel’s main public space will be the Atrium Lounge featuring a 27-metre ceiling with 200 satin glass windows.
The Fontenay will have two restaurants – an all-day garden restaurant with a terrace opening on to the banks of the lake, and a fine-dining outlet, Lakeside, whose head chef Cornelius Speinle formerly worked at Heston Blumenthal’s The Fat Duck restaurant in Bray.
The Fontenay Bar on the sixth floor features an outdoor terrace with panoramic views of Hamburg, while the hotel’s spa includes a 20-metre indoor/outdoor infinity pool and offers treatments by La Mer and vegan brand Ebenholz Natural Skin Care.
The hotel, which is a member of Leading Hotels of the World, is named after US shipbroker John Fontenay who settled in Hamburg during the 19th century.
