The architectural remains have already been described above in the accounts of the several excavated sites, but a general discussion of the various house types, their possible relation to one another, their development and origin has been reserved for the present chapter.

The best evidence for house plans of the First (Neolithic) Period is at Tsangli, where there is one complete example, and three others in fair preservation, one resting upon the other. At Sesklo, too, there are considerable remains, and also at Orchomenos; part of a house was uncovered at Zerelia, but the complete plan could not be ascertained. It seemed however to have been rectangular, and to be built of sun dried brick resting on a single course of flat slabs, in this respect differing from all other examples, which are built of wattle and daub with or without a stone foundation, or else entirely of stones, as seems to have been the case at Sesklo.

The Tsangli houses are all of the same square type with internal buttresses, and the existence of three superimposed houses, which differ only in the number of buttresses, shows that this type continued for a long period of time. The latest of this series may perhaps be contemporary with the earliest Second Period houses at Sesklo and Dhimini.
