Other early designs included Drum House, which boasted Scotland's first venetian window, and Mavisbank, both near Edinburgh. Mavisbank House, constructed between 1723 and 1727, was the first Palladian villa in Scotland, a collaboration between Adam and the owner, amateur architect Sir John Clerk of Penicuik. The latter claimed much of the credit, and certainly criticised some of Adam's suggestions, although evidence suggests Adam got his way on a number of points. As at Hopetoun, here Adam enjoyed an unusually close relationship with his client, despite their differences of opinion. His most ambitious early work was the baroque, Vanbrugh-inspired house at Arniston, near Gorebridge. Built for Robert Dundas, a lawyer and politician linked to the Earl of Stair, Arniston includes extensive grounds laid out by Adam, with a parterre and cascade, and a main avenue centred on Arthur's Seat to the north. The stucco work to the hall at Arniston is one of Adam's finest Vanbrughian interiors.
