I did a little research for you, I hope this helps:
TROY
CULTURAL STRATA
TROY I. (3000-2500 B.C.)
The first inhabitants of Troy built their houses on a 16 m. high, indigeneous rock at the western end of the ridge. The city was fortified by a wall made of rough stones. Today we can see only a short segment of this wall, some 12 m. long, and the main gate with two square towers. The thickness of the fortification wall is about 2.50 m. The other remains of the first Troy we can see today are some foundations of houses in Schliemann's north-south trench. These houses were long believed to be megaron houses. But according to the latest research they do not have megaron plans. Manfred Korfmann, the head of the latest excavation team, who cleared the trench and made some reconstructions there in 1988, calls them "row of long houses". "Megarons", the prototype of the Greek temples, were freestanding hauses consisting of a single room with an entrance hall. But these long and narrow houses, which were built of mudbricks over stone foundations, were not free standing houses. Some of them had the entrance in the corner. The stone foundation walls of some of these houses were built in herrinbone style. Although this type of workmanship is seen in Mesopotamia too, there was no direct influence since it was already known all over Anatolia and can be seen even today on the walls of some Turkish houses. We can also see the same design very often in the ceramics of Troy I.
We do not know much about the building technique but we think the fish bone designs on their ceramics show us that the artisans might well be influenced by their daily life. Fishing was a very important occupation for the first inhabitants of Troy. A fishing hook made of copper, which was found recently in the ruins of Troy I, strengthens this opinion.
In one of these long houses go infant burials were found just beneath the floor. One of them was in a shallow pit covered by a flat stone, the other one was in an urn. More examples of the same type of burial have been uncovered in open spaces in the city, but no adult burials were encountered in the acropolis. This can be explained by children's need for protection. They believed that babies, especially new-born babies, needed protection even after death. This is why babies were buried in the houses or in the gardens, and adults outside the city walls.
The Early Bronze Age inhabitants of Troy I made their tools of copper, stone and bone. Stone vessels and pottery were in constant use. All pots were shaped by hand, without the use of the potter's wheel. Some spindle whorls and loom weights have been found, showing that spinning and weaving were familiar occupations for these natives of north western Asia Minor.
Troy I, which had ten building phases, was eventually wiped out by a great fire.
