A great modern building

Off to another meeting in Barnet and a chance to visit and take a picture of another one of those station buildings designed by Charles Holden for the extension to the Piccadilly Line in the 1930s.
This time it is Arnos Grove.
It is stunning both inside and out.
But it is not just my feeling for this building!
The building features as one of the 12 "Great Modern Buildings" profiled in Guardian during October 2007.
Loads of glass with brick and reinforced concrete in basic geometric shapes.
The circular drum like ticket hall just rises up and the light just flows in.

By all accounts the design was inspired by the work of Gunnar Asplund and his work on the Stockholm city Library.
The design seems familiar as it is similar to that used for Chiswick Park on the District Line, although that also brick tower.
