A great kitchen ranks high on any home buyer’s wish list. But it takes a creative builder to offer a dream kitchen that owners can take with them if they move. Brazil-based sysHaus, an engineering and construction startup that will manufacture handsome prefabricated and sustainable houses in 2019, has begun doing just that, with help from architect Arthur Casas. For now, interested parties can tour a fully built model of the 2,100-square-foot, one-story steel house to preview its possible configurations, finishes, and sustainable attributes, which range from photovoltaic panels to a “bio-digestor” that converts organic waste into gas for the kitchen and fireplace. But perhaps most surprising are the kitchen modules that homeowners can relocate with ease.
