As the name of the building suggests this building was originally the boiler house for most of the college buildings (at the time) with piped water going underground to Founders via a tunnel that came out under 'the boog tube' near Founders West. It was built as one of the first building on the campus in 1886
There was rarely a reason for students to access the building (other than so they could get into the tunnels and get into Founders).
The building was converted for use as a performance space for the drama department and then further enhanced to include a digital studio, design workshops and rehearsal complex. It now also houses one of several cafe spaces around the campus. The picture shows this eating space but at some point I hope to find a picture that includes the two chimneys towering into the sky.
