Flats over the station is not a new idea at all as the Evening Standard’s headlines and editorial would suggest last week. You only have to look above Baker St tube station and see that Chiltern Court (180 flats) was built when redeveloping Baker St and completed in 1929.
When the Bakerloo tube line was extended North of Paddington over a century ago, tube stations like Maida Vale were in fact designed for “over station development” by local architect Leslie Green. Some were developed later like above the old tube station at Hyde Park corner. So developing above the tube station is not new. Incredibly we stop doing housing developments above tubes since those days till now!
