Streatham Art Deco Flats

In the last of the quarter-final heats, the designers transform two rooms each in glamorous 1930s art deco flats. A possible asbestos outbreak means work is halted for one of the designers. Will they complete their rooms on time? Meanwhile, the other designer might be going too far off brief with a butterfly-inspired effect which dominates heavily throughout the living room. Architectural historian Tom Dyckhoff takes us back in time and shows us that 1930s Streatham, meaning 'Hamlet on the Street', was one of London's most forward futuristic glamorous neighbourhoods.
