When the fishing station owners took up letting of "rorbuer", they started mass-producing them often with wood from their own forest. "Robber" from the mid 19th century don't differ much from the ones the fishermen built during the 18th century. They were small one-storey two-room buildings for one or two crews, their size only varying according to the kind of fishing tackle they used.
In 1929 a government appointed committee to study fishermen's living conditions toured fishing stations. As a consequence sets of blueprints for "rorbuer" were drawn up paying special attention to sufficient daylight and good air quality. Later on in 1939 the Ministry of Health issued regulations offering a 40% subsidy on repairs and restructuring of existing "rorbuer" and 50% for building new. The financial support was primarily offered directly to fishermen, and then fish buyers and fishing station owners, on condition that the provided blueprints were adhered to. These new "rorbuer" were not well received

they were cold and required technical solutions which were seen as unnecessary expenses. Accordingly, another set of regulations and blueprints were made after the Second World War. As early as 1923-1932 the Norwegian national lottery set aside nkr 50,000 of its profit for building "rorbuer" in Lofoten and Finnmark. These were called "statsbuer" (state cabins) and there are no easily accessible data on how many "statsbuer" were built and which of these were built according to the blueprints of 1939 or 1945.
