We have added new photos of the 30 Grosvenor Square development.

Qatari Diar has broken ground at 30 Grosvenor Square to develop a new Rosewood hotel in Mayfair.

The total cost of the project will be about £1bn. The hotel will comprise 137 guest rooms, five restaurants, six flagship retail units, a spa and a ballroom with space for 1,000 guests.

Abdullah al-Attiyah, Qatari Diar CEO, commented: "Today, as we break ground at 30 Grosvenor Square, marks a momentous occasion for Qatari Diar. The opportunity to transform such an iconic address is something that only happens once in a lifetime and we are extremely proud to be responsible for it. We recognise the history of the building and are dedicated to sensitively redeveloping the former US Embassy into a new destination on Grosvenor Square."

The project is due to be completed in 2023.
