Due to the continuing expansion The Portland Place School have leased a 8,300 sq ft (771m2) self-contained building at Harford House, 103-105 Great Portland Street, from The Langham Estate.

The Portland Place School is a successful secondary school (ages 11-18) providing a high standard of education for boys and girls. Due to the demand for independent secondary education in the area and their increasing waiting list, The Langham Estate was the perfect location to establish their second school.
