Does anyone know what it is ?

Almost certainly a new SER (signal equipment room) building for the
forthcoming resignalling of the Northern Line by Tube Lines/Thales.

Can't be, Tubelines doing some enabling work before it is actually required
instead of waiting until it is late. And then bollocking the signalling
