Homesteads often had several storerooms in which to store food and goods. The biggest storerooms could also be used for sleeping in summer. The floors of the storerooms were built so that animals could not get inside by climbing or pushing the floorboards up from underneath. Corner logs were often left at different lengths so that goods could be hung on their ends. The smallest storerooms, njallas, were built on pine trunks to store food on homesteads, in fishing and hunting grounds, and along migration routes.
