The urban nucleus of the Porcelain Factory of Vista Alegre reveals a special interest in terms of the evolution of the traditional adobe construction in the town of Ílhavo, located in the district of Aveiro. Presenting a structured philosophy of intervention in the terri- tory since its very beginning, it possesses a rich heritage in the field of construction and architecture. The measures planned and implemented in the second phase of Vista Alegre growth reporting its beginning to the ends of the 30’s, and along the 40’s, confirm it both in the rehabilitation, extension and new constructions in adobe masonry. Those measures were implemented during the structural changes of the Industrial Unit administration that only until this period belonged to the family of its founder. These changes creates one of the focus of innovation in the region, with new construction strategies and solutions in adobe buildings, which will prolonged the period of use of this construction system, noticeable in buildings dated of 1958 in the Vista Alegre and at least in 1970 in the town.
