Sir George Colebrooke of Gatton Park in Surrey commissioned at least two paintings from Barret.
 Colebrooke was a London banker and also became chairman of the East India Company.
He became the Member of Parliament for the rotten borough of Gatton in 1754 as a member of the Whig party and held office under the Marquess of Rockingham.
However, his financial speculations led to his downfall and he was declared bankrupt in 1777.

This painting was exhibited at the Royal Academy with its counterpart, a view from the house overlooking the lake and the newly landscaped parkland This painting shows Barret being influenced by Richard Wilson and moving towards a picturesque scene centred around a lake.
