Rebuilt by Sir James Miller, whose family made its fortune selling herring to Russia, Manderston is a masterful example of the no-expense-spared Edwardian country house. Designed by John Kinross, a young local architect, the original Georgian house from the 1790s was completely renovated between 1903 and 1905. The silver-plated staircase was modeled after the one in the Petit Trianon, at Versailles. Look for the collection of late-19th- and early-20th-century cookie tins.
There's much to see downstairs in the kitchens, and outside, among a cluster of other buildings, is the octagonal, one-of-a-kind marble dairy where lunch, dinner, or afternoon tea can be arranged for groups. You can reach the house by traveling northeast from Coldstream along the A6112 to Duns, then taking the A6105 east.
