Gold leaf and marble remain distinct features of the public rooms of the hotel, including the restaurants, with features more reminiscent of an English country house than a hotel. Considerable efforts to make the rooms soundproof at the Dorchester were made from the outset; the exterior walls were faced with cork, and the floors and ceilings of the bedrooms and suites were lined with compressed seaweed. Following renovation, the hotel was fitted with double glazing, and triple glazing on the Park Lane side to further improve soundproofing.
