In the suitcase house the rooms are all hidden away under the floor and used according to the tenants needs, for example a couple would have a much greater need for a study and library compared to a travelling group and a travelling group of people are going to require more bedrooms than a couple. Chang has cleverly design the house so that only the rooms required need to be opened and the rest can be hidden away. In my cabin design I have also tried to adopt this principle with a layout that maximises floor space by taking the elements only required by a couple and reducing the floor space to 75m2. The following diagram illustrates the links between public and private spaces and spaces that need to be accessible at the same time and those that don't need to be used at the same time.
