I have only just heard the sad news of the death of John Miller, an extraordinarily nice, thoughtful and avuncular architect, who did a wide range of good work, as described by Deyan Sudjic, his son-in-law (see below), including, which Deyan leaves out, the new ground floor of the National Portrait Gallery which opened in late 1993 and which John never particularly liked because of the touches of luxury – was it the marble floor to which he was allergic (it has now been obliterated by the latest reconfiguration) ?

I think his best work, as Deyan implies, was his excellent enlargement of the Whitechapel Art Gallery in the 1980s:-

And the way that Tate Britain was enlarged and reconfigured with its Manton Entrance and new entrance staircase which opened in 2002. Also, the Elizabeth Fry bulding at UEA:-

They were considerate and undemonstrative, like the man himself.
I have tried to find an image of him, but with difficulty. Neither the NPG nor the RIBA seem to have one, something which should be rectified. The only one I could find is by Sandra Lousada and I hope she won’t mind me reproducing it:-
