Since the creation of the first NFH prototype in 2018, a broad range of modular typologies have been built in response to the diverse micro-climatic conditions of Costa Rica. New and alternative construction materials have been developed to continuously improve the overall project performance. For the prototype of the wooden house, a laminated teak wood system has been engineered in collaboration with the national building industry and international expertise. The process results in a systemic kit of parts that includes columns and beams, as well as panels and connectors with different finishing options.

The systemic catalog of selected building components makes it easy for clients to choose from a pre-selected and varied range of sustainable construction materials that stimulate local and circular economies. Besides developing an innovative construction system, the project catalyzes the training of workmanship and students to engage with the innovative building techniques. The efficiency of the NFH in all areas, from design to construction and maintenance, makes sustainable homes an affordable reality for a broad customer segment.

The unique prototypes serve as a base for the serial reproduction of typologies that vary in size and cost. Homeowners can choose from an ample range of pre-designed options, or customize their NFH according to personal budgets and needs. The project supports integral sustainability and regenerative development in terms of its ecological, socio-economic and spatial performance.
