He was appointed to a commission in 1680, charged with seeking out and punishing Covenanters in Peeblesshire, particularly those who had been at the Battle of Bothwell Brig in 1679.

He was appointed "Sole Master of Work, Overseer, and Director-General of their Majesties' buildings" on 24 December 1689 by King William III, filling the post which had been vacant since Sir William Bruce's dismissal in 1678.
