Earlier renderings ( on the Gow Hastings website, for instance ) indicate a building where the decorative exterior colour was kept in check, drawing the eye to the life and activity inside. Either way, though, the ground floor blinds are often drawn when I've walked past, which is a pity. The relationship between the addition and the earlier, mid-1980s building suggests one-upmanship rather than symbiosis - the two don't look related, though they're reasonably well linked on the inside and the atrium is a focus of activity that ties the place together on all floors.
