I walked past it this morning and now the hoardings are down, it looks even worse. The ground level of the main block is clad with this horrible brown / black marble previously only seen in up-market chippers. The entrance is unenticing and the whole ensemble screams bland.
I reckon the architects managed to win an argument with O'Callaghan to get budget for an 'architectural statement' on the corner but for the rest - it was dictated by a tight budget.
Compare the street level facade to the nearby Fitzwilliam which manages to be enticing even while walking past, encouraging you to wander in.
