Last thing we built at ours were a couple of £39 wardrobes from Ikea in November 2015. Had got rid of the old wardrobes we had because they were too big and it was a bit of a 'if it lasts a few months, it’ll do the job" purchase. Still standing solid.
Last flat-pack we did was probably the chests of drawers in the sister-in-law’s flat back in June.
