Currently there's three exhibitions going on. One is for the Crossrail 2 project, the second is about digital design and construction, the third about modular design concepts to try and solve the chronic shortage of housing in London. I really enjoyed the latter, especially how quickly a new high rise building can be built using "factory manufacturing" techniques for building homes using pre-built units.

The lower floor seems to be some kind of sales convention with lots of companies in the buildings trade hawking their products. It was a Saturday when I visited and all the booths were empty, which was actually quite good because I got to wander around and actually look at stuff without getting harassed by sales.
