An intriguing thought reaches me as to why Michael Hopkins and Partners' Parliamentary Offices and Westminster Station are so far behind schedule. If you're digging a large hole in the ground at Westminster, might it not be sensible to take the opportunity to make it a bigger hole so that, let us say, an entire nuclear-attack-proof government command centre could be fitted into it? The plant is already on site, the location is ideal, attention on such a sensitive project can be diverted, and any blame for cost and time overruns can be off-loaded onto the poor old architect. That Bechtel - erstwhile executives include George Schultz and Caspar Weinberger - has been appointed to finish off the Jubilee Line does little to contradict this theory. Few construction firms can have as much experience of building nuclear shelters.
