Motcombe Court was designed by the architect Henry Tanner F.R.I.B.A. in the 1930's. Tanner was one of the most celebrated architects of the pre-war period. He held the post of President of the Architectural Association and completed some of the most important commissions of the time in London including the Dickens & Jones Department Store, Strand Palace Hotel, Oceanic House for the White Star Line at Pall Mall and others. The Park Lane Hotel in London is perhaps Tanner's best known work and is frequently described as one of the finest 1930s buildings in London.

Motcombe Court was built by the eminent company Walter Lawrence and Co. Just before erecting Motcombe Court they had built the Masonic Hall at Great Queens Street, London, Surrey County Hall at Kingston and the Odeon Cinema at Muswell Hill.They also built the laboratories for Metropolitan Water on Roseberry Ave and the Royal London Mutual Insurance building in Finsbury Square (at the time the tallest building in London).
