Arthur George Sydney Mitchell was a Scottish architect. He designed a large number of bank branches, country houses, churches, and church halls. His most significant commissions include the housing developments at Well Court and Ramsay Garden, both in Edinburgh.

Ramsay Garden is a block of sixteen private apartment buildings in the Castlehill area of Edinburgh, Scotland. They stand out for their red ashlar and white harled exteriors, and for their prominent position, most visible from Princes Street.
