The ladder and newly constructed oven in the Replica House in 2002. As in many other houses at Çatalhöyük and in Building 3 in its later phases, the ladder and oven are in the southeast corner of the building. The doorway that can be seen to the right of the oven is to facilitate the entrance of modern visitors to the Replica House, since entry down the ladder might be difficult. Side entrances have rarely been found in Çatalhöyük houses. However, at the beginning of its history, Building 3 had a side entrance in its eastern wall, which was later blocked.
