JW Marriott has officially unveiled central London's historic St Pancras Renaissance Hotel, which follows the completion of an extensive £150m restoration of the Victorian property.

Manhattan Loft Corporation worked alongside contractor Galliford Try; RHWL Architects; conservation architects Richard Griffiths; and GA Design International on the scheme. Facilities at the 245-room hotel include a 6,226sq ft (578sq m) spa area, which includes five treatment rooms and a couple's suite; a spa pool; and a relaxation area.

France-based supplier Cinq Mondes has been appointed to devise the treatment menu at the hotel, which officially opened 138 years to the day after the Midland Grand first opened on the site. Other facilities at St Pancras Renaissance boast chef Marcus Wareing's flagship restaurant - The Gilbert Scott - and the Hansom Hall, a banquet area capable of accommodating 550 people.

Tina Edmundson, senior vice president of lifestyle brands at Marriott International, said: "Renaissance believes in discovering the hidden gems of every city, and I cannot imagine a greater or more unique find."
