This site is located in the place looking out the refreshing south sea around the Gulf of Suyeong, Haewundae. As it was possible to develop the site as officetel site in accordance with the guideline of the city planning, the residential officetels of 50~80pyeong were planned and the layout and the type of residential buildings were decided to maximize the advantage of the sight view to the surroundings of the Gulf of Suyeong. The arrangement of the officetel houses from the 4th floor to the 47th was planned to secure the sight view and the sunlight preferentially, and at the 4th floor the deck only for the officetels to reserve sufficient green space for the residential units, and thus we attempted to establish the environment-friendly complex to feel the nature with the surrounding environment of the site. Also, the arrangement of the neighborhood life facility, the parking lot for officetel and the welfare facility only for officetel were planned at the lower part from 1st floor to 3rd, and the mass was constituted where the entire continuity of the street view and the open space can be mutually harmonized, integrating the whole building.
