Patrick Home had built Paxton House, but on inheriting Wedderburn Castle in 1766, commissioned Robert Adam to re-model the Castle and furnished it with furniture from London designer and cabinetmaker, Thomas Chippendale Junior. Wine bottles were stored in the pull-out cellarette drawers. In the right back corner, there is a small cupboard door to hold a potty. Men would use this whilst drinking in the Dining Room after the women had departed the table for the Withdrawing Room.

At this point in time, Patrick was MP for Berwickshire (1784-96). From c.1771, he had helped his brother-in-law, John Graham, who owned the Douglaston estate in Grenada from 1768 and several plots on Tobago, manage his sugar plantations as an absentee landlord. John stayed at Wedderburn until his death in 1782. Patrick was an executor of John’s estate. This meant that Patrick, along with his fellow trustees, was responsible for selling the land (in 1790) and the enslaved people that his brother-in-law had owned.

The Douglaston estate was advertised in The London Gazette, 31 July, 1790, p.485
