then appointed another architect, who made changes to the design. However, the building, which now serves as the City Chambers, is still often attributed to John Adam. On Robert's return to Britain, he established himself in London, where he was joined by the younger brothers James and William. John continued to look after the family's Scottish interests, investing in further quarrying ventures, and the Carron Iron Works. He supplied his London-based brothers with capital from the Blair Adam estate, at least until the collapse of a stock market venture by his friend Andrew Fairholme in 1764 left him out of pocket. Further losses occurred after the failure of Robert's speculative Adelphi development in 1772, and John was forced to mortgage Blair Adam. John Adam designed other houses in Edinburgh and the surrounding area, including Milton House in the Old Town, Hawkhill House, near Leith Links, for Lord Alemoor and Kerse House nr. Falkirk for Sir Lawrence Dundas (all now demolished). In the Annandale town of Moffat he designed Moffat House for the Earl of Hopetoun. Among his more significant work was Adam Square, a speculative development of three houses on his own property in the city. The development, although not a true "square", represents one of the first terraces of townhouses in Edinburgh. Construction began in 1761, and despite the financial troubles, Lord President Robert Dundas was able to move in by 1768. Adam himself also lived there until 1772, as well as having a villa at Merchiston. Adam Square was demolished in the 1870s, and the site is now occupied by Adam House, a building of the University of Edinburgh. In Edinburgh he lived at Niddry's Wynd (now known as Niddry Street.) Upon his death in 1792, he was succeeded as laird of Blair Adam by his only surviving son, the politician and judge William Adam. He is buried in his father's mausoleum in Greyfriars Kirkyard in Edinburgh. It is the largest monument in the graveyard and stands just south-west of the church. Family He was married to Jean Ramsay of Abbotshall in Fife (d.1795).
