In particular, steel structures with the advantages of fast construction, cost saving and aesthetics are becoming a popular construction trend for many residential houses in many countries around the world. In addition, using shaped steel to repair and increase the storey for existing buildings is effectively chosen by investors. This research was conducted for office buildings to increase from two to three-storey buildings. The foundation structure was calculated and tested for sufficiently bearing capacity when raising storeys. Columns and beams were designed with V- and I-shaped steel. This method reduces the load on the foundation compared with reinforced concrete structures and meets the needs of today's society.
