The many discoveries of buildings in the North of France allow to present a first assessment on the domestic architecture of the end of the Neolithic. From several complete and well preserved plans, these wooden buildings constructed in the the first half of the IIIrd millennium BC during the main expansion of the group Deûle-Escaut, were placed back in their geographical contexts, dimensions and constructions systems compared. Different architectures probably reveal several functions. Some buildings have an undeniable ostentatious character and some settlements are surrounded with fences. A few small buildings, less frequent, are located in open spaces next to medium-sized buildings, with floor surfaces which exceeding 100 sq m. In spite of big differences, the resemblances are numerous. Preservation of the proportions in the internal organization and similar architectural patterns from one building to another, throughout a wide geographical area, illustrate a know-how sharing evolving between 2900 and 2400 BC. 

Morphological variations of these features overof five centuries offer the opportunity to propose a model of typo-chronological evolution for Northern France.
