Central to building B is a large, ground floor room from which it was possible to access other rooms in the building, including the first floor and the basement. Clay tablets were found in the remains of house B, again indicating its use as an administrative centre on the upper floor.
John McEnroe in his book Architecture of Minoan Crete points out that Building B, although it may have predated Building A, is in fact very similar to the later building. It is approximately the same size as the earlier section of Building A and the design of the two buildings is strikingly similar. The same functions seem to have been carried out on the ground floor of each building. At the heart of both buildings there was a light well and they both had a Minoan Hall. Both buildings had storage magazines and staircases to an upper floor. Even the main entrance to the two buildings was located in the same place in the middle of the southern wall.
The rooms that are visible to the visitor today are basement rooms and as the photographs below demonstrate, they are very well preserved with some walls reaching over six feet (two metres) in height. Visible in these rooms are the remains of doors, windows, cupboards and even wooden beams.
