At the International construction Trade Fair (SASO), held from 25-28 October 2017 in Split, Croatia, PROMO demonstrated its line of low-energy prefabricated houses. A house of 40m2 was used as a display model. PROMO’s stand was one of the most visited at the fair. Aside from being attracted to the stand’s appearance and presentation, we were pleased to note that our visitors showed considerable interest in learning more about designing and building houses focusing on the selection of materials and promoting technological advances that save energy and are ecologically cutting-edge. PROMO is universally recognized for building such houses.
