Many LEGO models have been proposed for tube stations and tube trains, but now, at last, a model has been proposed for the tube’s head office.
At least, a model of 55 Broadway, the former headquarters of the London Underground.

Designed by legendary architect Charles Holden, the building was the tallest secular building in London when it was completed, and was so tall that the council banned it from using the top floor in case it was too high for office workers.
Created from over 4,700 bricks, the model would be nearly half a metre high – so practically a skyscraper of LEGO proportions.
The model is a concept at the moment, as part of LEGO’s scheme to encourage people to submit plans to them.
You can vote in favour of the concept being turned into a commercial product here.
