Different nations and tribes pass through the Bulgarian lands.

The construction of houses depends critically on the age and geographical area.

The most ancient prehistoric dwellings have been found in excavations of the mounds near the village Karanovo . Many of the houses are dug-outs , with only the roof remains above ground.

Traditional Thracian houses are usually foundations of stones with a solution of mud on them and wooden frame filled with adobe , wooden roof with lining of stone, plastered with clay, on which are placed flat tiles.

Neolithic dwellings 

 Building 6200 - 6300 BC evidence of unexpected construction skills. Two of them Assoc Leshtakov defined as scientific challenges. 

The first is the art of these people treated wood. They did a real beams - 40 to 40 cm boards 2 cm thick in patterns that are printed from the tree in the clay. Have an assembly, had doors, all things that civilized people use. The second technology is "sliding formwork" to elevate homes. I think this is about building innovation can even talk about real architecture, says archaeologist. 

In Neolithic sliding formwork used clay. It fills a wooden formwork of a meter  covering building in ring. After the tree is burnt on site to baked clay. Builders same operation repeated at the next level until they reach "to the roof." 

Neolithic dwellings in Stara Zagora , dating back 5800 years BC were on two floors. Building with a total length of 10 meters and a width of 5.6 meters . It is assumed that the height of the house was at least 7 meters and the ridge was held by two rows of wooden pillars . On the west wall of the two rooms are located granaries in each of them has a clay oven . Near the furnace are placed flour mills of mill stones and benches .

In the Late Bronze Age Thracian started to strengthen their villages - first with earthen ramparts , which later escalated into stone walls without mortar or only bonded to mud solution . Their homes were planned around the center and spaced to be able to switch from one to the other. City are ground as their walls were made of poles impaled in the ground around which was woven network poles plastered with clay. Typical of the early Thracian housing Late Bronze Age was rounding one of the short walls as apse and deploying against her entrance . Usually entrances were located in the south, which is dictated by the harsh climate of Thrace.

 The majority of the Thracian population in the Late Bronze and Early Iron Age inhabited the vast unfortified settlements, located in the plains of convenient river terraces or low sloping sides , often surrounded by rivers and deep ravines , ensuring their natural protection . Housing in these settlements are connected by enclosed courtyards which are facilities for livestock, grain storage warehouses and other outbuildings. Few , probably ten to fifteen such residential complexes formed village. Settlements of this type are found throughout Thrace.

Centuries ago there was a house on a natural hillside near Tundzha River in the territory of the present village of Knyajevo .

Built around 330 BC . Two Storey building with a total area of about 600 meters with huge walls at the base of the hill. Built on a stone wall , upgraded from adobe and covered with tiles. Water supplied. The villa had a bakery ovens , furnaces for melting of metals and others.

 Thracian home with basement. Large amount of space on the first. floor was used for storage and service rooms - kitchen , looms found To this main building is adjoined other buildings. In one of them found eschara - it's a ritual fireplace, this large hall probably signed the most important contracts and perform different sacrifices. There were many furnaces , where ore is processed .

Late antique residential building "EIRENE". 

Peristyle building built in the III - IV century and probably used as the residence of a prominent citizen of Philippopolis. In relevant part of the building There are colorful mosaics which have geometrical forms and figures. The rooms in the southwest are household and business - they found a large quantity of pottery.

The eastern part of the representative areas of the housing complex. The occupants of the house had enough money and enthusiasm for building renewed after every devastating invasion as that of the Huns in 441-442, they even made a renewed building more beautiful and magnificent than the former, and in the IV-V century residential rooms were decorated with beautiful mosaics. Each room of the master pieces produced under hundreds of thousands of pebbles, shards and glass smalt forming exquisite compositions of geometric shapes, eternal knots, flowers and congratulations to visitors. The property was abandoned forever about the end of the VI century.

The residential towers are homes of feudal lords. Residential towers began to be built in the Bulgarian lands in the Middle Ages, before the Ottoman invasion.

Medieval defensive tower of the port (arsanаta) in today Uranopoli resort town on the border with monastic republic Mount Athos. The lower part of the stone walls of XI-XIII centuries period. The tower was built by Tsar Ivan Asen II in the 1230-1232 year.

The Hrelyova  tower-like and the Athos has roughly the square plan 

(7,75 x 8, 25 m) and a height of 23 meters. Its walls are thick 1 80 m and are completely solid, made mostly of stone grout. To each side of them incorporating pilasters powerful 3 (total of 12) which are associated with arches. In arhivoltite arches and angles between them is decorated with brickwork. Pilasters have enabled the top floor of the tower to be developed on a larger area and include a chapel with a gallery encircling three sides.This gallery has round holes and window openings, which if necessary may also have served as loopholes. Now the tower ends with platform and pinnacles, but it is not part of its original architectural character. The ground floor now looks partially buried as a result of centuries of accumulated material on the surrounding terrain. During the construction of the ground floor flat with the ground, but no entrance for safety reasons.The entrance is on the first floor of more than 2 meters above the ground, and the entry was done with an external wooden staircase probably Lift. Climbing the floor becomes stone stairs built into the walls. Inside the space is divided into a ground floor - with an overhead frame and arched five floors, separated from one another by wooden floors. Floors from first to fourth are equipped with holes ( loophole ), which are the only openings for lighting, as well as for the floor (on II floor) and bay exported latrines (III and IV of the floor).

The Bolyar  house is located in the eastern part of the town of Melnik, ten minutes from the city center. It is a monument of national importance to the Bulgarian medieval architekture.Bolyarskata residential house was built in the first half of the XIII century.In the following centuries the building was reconstructed several times. During the late Middle Ages and the Renaissance, it was  richly furnished house in Melnik area. Courtyard was paved with marble slabs, there were fountains marble statues, halls and rooms were of mosaic floors, frescoes, stained glass windows.It is known that the Bolyar house was inhabited until the early XX century.

Are almost completely preserved facade walls and internal transverse partition wall connected to the northwest and the southeast wall and front walls of the tower with a large cellar.Remarkable brick decoration on the main body and the walls of the tower. These decorative pieces of bricks are a good example of medieval Bulgarian picturesque style of architecture.During archaeological excavations next to the walls of the tower were the owner's house, water reservoir and a small church, dating from the beginning of the XIII century .
