The present article gathers examples of modular dwelling concepts, where Cross Laminated Timber (CLT) and other timber-based products are the primary elected material, and makes comparisons between the ‘prefabrication construction process and marketing strategies’ for modular dwellings with the ‘automotive industry’. The article is divided in three parts. First section of the article provides an analysis of the environmental impacts of transportation and building sector, then identifies reaction trends between electric vehicles and prefab modular homes. The second section deals with work flow, emphasizing the prefabrication process of house modules, the constraints given by transportation and storage, and arguing for the personalization of a mass production product demonstrated through six case studies. The third section debates possible marketing strategies, evoking business models based on collectible concepts, cataloging, mass customisation principles and image/brand for tourist/urbanistic developments.
