You may already be familiar with Florin Court, No. 6-9, the only residential building in the square, but under the name ‘Whitehaven Mansions’. It's the backdrop to the Poirot TV series as the fictional home of Hercule Poirot, Agatha Cristie’s detective (who, although imaginary, is still the only famous Belgian anyone can think of).
It's a magnificent Art Deco building with a lovely curved frontage, designed by Guy Morgan and Partners and built in 1936. It was probably the earliest of the residential apartment blocks in the Clerkenwell area. The walls were built in yellow and brown bricks, specially made by Williamson Cliff Ltd and placed over a steel frame. The cantilevered entrance canopy is covered in copper and steel. Regalian refurbished the building in the 1980s, to designs by Hildebrand & Clicker architects, to provide 125 two-bedroom flats and studios. They gave it a swimming pool in the basement, also in Art Deco style, and a Jacuzzi, and they gave it the name, Florin Court. Unfortunately (for architectural purists) Regalian tiled over the original Art Deco foyer. It has a lovely setting overlooking the square, and it is all very peaceful and quiet..
