designed by Dick Peddie & Mackay and built in 1898 as a five-storey car-showroom which must make it one of the earliest not in Scotland, Douglas House is dominated by large street-facing arched windows flanked by symmetrical bays of narrow double windows with dominant keystones, triangular pediments and bullseye windows to the attic floor. A 1908 OS map shows the showroom when the adjoining Sunbury Distillery was still in operation. The projection on the east side was a car elevator to transport vehicles between the floor-levels.

JM Sloan & Co specialised as distributors for Wolseley Motors, a British luxury car manufacturer established in 1901 and hugely popular by the 1920s, become the largest car manufacturer in Britain during that decade but falling out of favour after the Second World War, although Sloan continued to be a distributor until well into the 1950s.

At some point between 1914 and 1933, the rest of the Sunbury Distillery buildings were removed and Sloan built a street-fronted garage at No 59 knows as Sloan’s Garage maybe incorporating some of the old distillery buildings to the rear. By 1925 their business was incorporated as the Edinburgh Western Garage Company, although the Sloan name was soon revived.

An undated photo from the mid-20^th century shows the garage taking in the slope of the street with a small basement level at the junction of Belford Road and Sunbury Mews, including a prominent corner block with a pyradmidal roof and urn finials; Douglas House and its car elevator can be seen behind. In 1981 both garage and elevator were swept away and a functional new brick-built office block built in its place called Belford House for the Health and Safety Executive. That has now been demolished, and Douglas House is being renovated along with new build to create an apartment block.
