Built 1936-1938 to the designs of architect John Murray Easton. This view shows the stairwell. The building has been converted into flats. "The Laboratory Building at No. 177 Rosebery Avenue, on the east side of New River Head, was built for the Metropolitan Water Board in 1936–8 for water testing. The board's laboratory staff of seventy had responsibility for monitoring biological, bacteriological, chemical and chlorination aspects of London's water. This was done in a strikingly suave building designed by John Murray Easton, of Stanley Hall & Easton and Robertson, a firm beginning to specialise in medical and scientific buildings. The builders were Walter Lawrence & Son Ltd." - Link
