How’s this for a job advert? “Palace. World Heritage Site. Location Westminster. Thousands of tons of soft, sculpted limestone – including one huge tower and one enormous clock – built in the 1840s and resting on a muddy island in the River Thames. One not-so-careful owner. Multiple repairs and widespread restoration needed. Timescale and cost range from 32 years and £5.7 billion to six years and £3.9 billion depending on inmates’ willingness to move out partially or wholly while works undertaken. Project manager needed.”
