Florin Court is an Art Deco / Streamline Moderne Grade II residential building on the eastern side of Charterhouse Square in Smithfield, London.

Built in 1936 by Guy Morgan and Partners[1] who worked until 1927 for Edwin Lutyens, and two years earlier successfully completed the similar Cholmeley Lodge in Highgate, it features an impressive curved façade with projecting wings, a roof garden, setbacks on the eighth and ninth floor and a basement swimming pool.

[2] It was probably the earliest of the residential apartment blocks in the wider Clerkenwell area, immediately north of the City of London, Metropolitan Borough of Finsbury, now Islington.

The three-story Georgian buildings that stood between 6-9 Charterhouse Square before Florin Court used to be a vicarage and a lady's school until 1859, that was later converted into a staff dormitory once purchased in 1872 by Copestake, Crampton & Co. Ltd (lace manufacturers and wholesalers located in Cheapside).

[3] Copestake, Crampton & Co. Ltd employees' hostel housed up to 100 male and 18 female, but once the company started to move to Nottingham the building was sold to balance part of the loss due to the business slowing down around 1934.
