22, Frith Street W1

No. 22 Frith Street is a terrace house rebuilt around 1900. It features red brick with stone dressings and has a slate roof. The building stands four storeys tall with an attic and has a single bay front. The ground floor, which is rendered and dates from the mid-20th century, includes a shop. A broad segmental arched window on the first floor is surrounded by rusticated stone, while the second and third floors have narrower three-light sash windows. At the top, there is a stone-faced segmental pedimented dormer. The house is adorned with a mutule cornice and framing pilaster strips. It is listed for its historical association with J.L. Baird, who used an attic laboratory here from 1924 to 1926 to demonstrate television transmission on January 27, 1926.
