"[One Aldwych] quickly became known for its blend of Edwardian grandeur and splendid Parisian elegance. Its distinctive features include curved corners, a coppered cupola dome and a mansard roof of Westmoreland slate, whilst decorative features such as female head keystones, cornices and low balustrade balconies add to the charming Parisian feel. It is still often described as Mewes and Davis’ finest work and is thought to be one of the most important Edwardian buildings in London. " ~ http://www.onealdwych.com/our-story/history
