The case study presented here is the House of the Razed Rooms of Ayia Triada (Crete, Greece), one of the most important site of the Minoan civilization, excavated by the Center of Cretan Archaeology of the Catania University under the direction of the Italian Archaeological School at Athens. This house, built and used during the XIVth century BC. (Late Minoan IIIA2), located in the North-Eastern part of the settlement (Villaggio), North of the Villa, was so deeply damaged by many subsequent activities that it became indispensable trying to create a virtual model to analyse its architectural phases. Discovered by Federico Halbherr in 1911, the House of Razed Rooms, built on two superimposed terraces, takes its name by the razing of the walls of the upper terrace, and the covering and the requalification of the structures of the lower one, carried out when a new plan of this area was designed in the second half of the XIVth century, after the fall of the Knossos palace.
After the excavation of 1991, when only the southern part of the building was uncovered, in 1983 V. La Rosa completed the exploration of the house, discovering the complete plan with a main L-shaped corridor (n. 2) with two groups of modular rooms (n. 5, 6, 7 in the western side and n. 1, 3, 4 in the northern part). The corridor 2 had a floor of 1.50 m higher than the other six rooms, that were accessible through trapdoor from the top. The entire building had a length of 20.10 m in North/East-South/West sense and a surface of 180 m^2; the walls had a thickness of 0.80-0.90 m with foundations on the rock. The plan, the thickness of the walls and the absence of a direct connection between corridor 2 and the other rooms seem to suggest that probably this building has not residential function. Furthermore, the subdivision of the space in the same modular unities is a feature, present in some contemporary buildings of Greece like Gla and Mycenae, that has to interpreted as the mark of structures used as warehouses. In this context, it is possible to identify the two groups of rooms 1, 3 e 4 e 5-7 of the House of the Razed Rooms as silos used probably for the long conservation of cereals and legumes.
