We had a meeting at the headquarters of Pentagram this afternoon in what was once an old dairy off Westbourne Grove where the horse-drawn milk carts would load up.   It was bought by the original partners of Pentagram in the late 1970s as their offices, meeting rooms, workshops and archive on the ground floor, open plan on the top.   I saw the workshop where Kenneth Grange designed the Intercity 125 and the later London taxi and sat in a meeting room opposite some of their classic logos, not just Alan Fletcher’s design for the V&A of 1990 (it was required to be ‘functional, dateless, memorable’) and Harry Pearce’s logo for the RA, but also Berry Bros & Rudd.
