This research handles the analysis and design of sustainable and affordable house concepts in the Netherlands, focusing on the row house typology. Sustainability is defined based on 6 value domains and an assessment method is used which is able to combine all topics of interest. Each topic is analyzed based on the description of assessment, the performance of current housing stock and the possibilities for improvement of that topic. All outcomes of preliminary work, interviews with experts and topic analysis were combined in two conceptual directions: passive and active. These concepts were assessed and compared in order to find the performance and robustness of them. The recommendations for improvement which could be concluded from that were implemented in a hybrid concept. This performs within the boundaries of an accepted selling price and could reduce the ecologic impact of the house concept.
