This is the Corner House on the High Street a former doctor's surgery, everybody knows it. It was renovated by T-Space architects who are on the upper floors, Age Concern occupy the ground. The interesting thing is the plaque on the Grove Park side of the building, it is for James Bradley. Bradley, 1693 - 1762, was the third Astronomer Royal and according to the plaque 'was first to demonstrate that the earth moved around the sun'. I believe his observations were made from The Rectory in Wanstead, now whether that was on the site of the Corner House or not I do not know. As ever any further information welcome.
