Opened in the late 1920s, the Grosvenor House hotel boasts frontage along Park Lane across from Hyde Park and encompasses the entire block between Upper Grosvenor Street, Mount Street and Park Street in the most coveted London postcode. The restoration will encompass its exterior facade, guest rooms, public space, dining areas, health club, kitchens and the addition of spa facilities. Upon completion, the hotel will offer 498 guest rooms and will be rebranded The Grosvenor House, a JW Marriott Hotel, the first property to carry this flag in the United Kingdom. The Shelbourne originally opened in 1824 and is located on St. Stephens Green in central Dublin. In 1922, the Irish Constitution was drafted and signed in the hotel, and the property still plays a prominent role in Irish society.
