Much altered internally and extended over the years, today it is the registered office of the Royal Bank of Scotland and its parent, NatWest Group and is protected as a category A listed building.

[3] Sir Lawrence Dundas saw the layout and decided the church site would make a good location for a prestigious town mansion, and in 1768 he acquired the land.

Much of these alterations were removed by John Dick Peddie in 1857 when a banking hall with a distinctive pierced dome was added to the rear of the existing house.

[5] In 1834, a statue of John Hope, 4th Earl of Hopetoun, who had served as Governor of the Bank 1820–23, was placed in the garden in front of Dundas House.

The statue was originally commissioned in 1824 by a group of high ranking persons in Edinburgh, led by James Gibson Craig, from the sculptor Thomas Campbell.

Although several sources state that the statue was designed for Charlotte Square, there is no evidence of any plans for locating on that site, and Hope's link to the Royal Bank make Dundas House a more obvious first choice.

The house is built of cream sandstone ashlar, weathered to light grey, from Ravelston Quarry some three miles to the west.
