A three story block of seven shops and offices with flats above, on the corner of London Road and Locks Lane, postcode CR4 2JA.
Eric Montague, on page 5 of Mitcham Histories: 14 Upper Mitcham and Western Road, said it was named after William Frederick Laing, who founded the estate agents Seymour Laing and Co.
Mitcham Borough Council minutes, page 131, of 7th December, 1938, said that the block was given a name as there were only four numbers available in London Road, which wasn’t enough for all twelve flats.
