What do you do when you’re early for a meeting? grab a coffee? Perch somewhere with your laptop? Or explore? En route to a private dining room at the lovely St Pancras Grand, we seized a slightly-early moment to marvel at John McAslan and Partners’ gorgeous King’s Cross roof. It does what good sculpture does: makes you want to walk around it and under it, get up for a high view and enjoy what the cast shadow does to the structures around it. A treat.
