RETIRED BBC journalist Tim Sayer and his wife Annemarie Norton, theatrical costume maker and former ballet dancer, live in a modest north London terrace.

Its exterior looks much like neighbouring houses but stepping inside is to be transported into a wondrous domain whose every surface is crammed with art.

Paintings, drawings, photographs, prints, sculptures, antiquities and tribal art by predominantly living British artists greet you from all walls, ceilings, both sides of doors, floors and the staircase. They’re even in the bathroom and toilet.
