Hopetoun House near Edinburgh was started in 1699 by the 1st Earl of Hoptoun, Charles Hope. It describes itself as "Scotland's finest stately home". It was designed by Sir William Bruce but enlargements were made in 1721 by William Adam. It was Adam who introduced the sweeping curves and extra apartments. Interior decoration was not completed until 1767 and much of that survives to this day. It is also still the home of the same family - though now elevated to Marquess of Linlithgow.
