Abstract
In a building construction operation, two sets of rules, which are construction law and consumer law,are superimposed to bring a level of protection to the consumer purchaser of real estate. Correlatively,they generate many obligations for the professionals. The objective of this research project is thereforeon the one hand to provide an inventory of the various protection issues arising from the cumulativeapplication of these two branches of law and, on the other hand, to propose settlement solutions in caseof "conflict". Although the positive consequences of such a combination are undeniable, this studywould not be complete if one did not also take into account the perverse effects which this dualprotection may entail in practice with regard to the economy of the contract, the building sector and thespirit of construction law in a more general way. The aim is to make law more effective in order tosecure, as far as possible, the construction operation for all the players in the sector: for professionals totake stock of their responsibilities and obligations (entrepreneurs, promoters, architects, bankers,solicitors …), than for the "real estate consumer", who must be able to have a clearer view of thecontracts submitted to him so that his consent might be truly informed.
