His first commission seems to have been for extensions to Hopetoun House, near Edinburgh, for Charles Hope, 1st Earl of Hopetoun. Hopetoun had been built only 20 years before by Sir William Bruce, and Adam was retained to rebuild the south-east wing. These works, completed in 1725, aimed to give the east front a bold new facade, stepping forward at the ends with curved sections. According to John Fleming, "nothing so ambitious or imaginative had ever before been attempted in Scotland". Over the following years, Adam would return to Hopetoun, building the south colonnade from 1726, the north wing from 1728, and finally the pavilions from 1736. These were not finished until 1742, the year of the Earl's death, and the completed scheme was finished by Adam's sons after his own death. Adam also laid out the gardens, possibly to designs by Bruce, whose axial style they follow.
