John Tasker, architect and builder, was born in London in 1738. He later worked on Mortimer Street, Cavendish Square, where he housed his own practice. Tasker was much employed by Thomas Weld of Lulworth Castle, Dorset. There Tasker was responsible for redecorating the interior (1780-2) and building a domed Roman Catholic chapel. In 1811, Tasker created the Greek revival facade of Spetchley Park, Worcestershire, as well as repairing 17 Portman Square.
On a few occasions Tasker presented at the Royal Academy.
