In 2013 the opportunity arose to purchase the house to the left of the brewery. Besides the building itself, also the ground in the back of the brewery was part of the lot. This gave Oud Beersel room for future projects. The house was transformed into a brewery shop on ground floor, and later on, offices and a tasting room for the brewery visits were installed on the first floor.

After reinforcing foundations, the small room where the brewery shop was held before, turned into a small foeder room with 3 foeders of 38 HL. Above this room, on the first floor, a new barrel room was created as well, to increase stock of lambic on wooden barrels.
