A method for storing containers in an automated storage and retrieval system includes a framework structure including upright members, horizontal members and storage columns provided between the members. Storage containers are stackable in stacks within the storage columns. The method includes: defining a first storage area, wherein the first storage area includes specific storage columns within the framework structure; setting a first maximum weight threshold for the first storage area; determining a total weight for all storage containers stored in the first storage area; determining a weight for a further storage container which is to be stored within the framework structure; and determining a storage position for the further storage container to be within the first storage area if the sum of the total weight and the weight of the further storage container is below the first maximum weight threshold, or determining the storage position for the further storage container to be outside of the first storage area if the sum of the total weight and the weight of the further storage container is above the first maximum weight threshold.
