The use of steel in the building structure also contributes to sustainability due to its ability to be recycled multiple times (Noriega, J 2012). Though more expensive

than timber, steel is highly durable and has a very long lifespan, which prevents the need for regular maintenance (Stålbyggnadsinstitutet, 2013). -
