The building housing the Omnibus Theatre, next to Clapham Common, was a library until 2012. Local residents rejected plans to turn it into expensive flats, and now it's a community theatre.

They've recently received a grant to re-floor one of their spaces, so it can be used as a rehearsal room, as well as a space for receptions.

Rob and John's task was to remove the existing carpet tiles. This turned out to be one of the most difficult tasks of my five years doing GoodGym. The tiles were so well stuck down, I suspect they were installed in a previous GoodGym Wandsworth task.

Nearly two hours of hard work removing the tiles gave us a really good workout, but we had enough energy left to lift two tables up some winding stairs.
