Korean architect Kim In Cheurl designed the innovative Urbanhive tower located in Seoul, South Korea. Urbanhive is a 17 levels of 70 meter high tower with white exposed concrete and contextually sits on the corner of the street within the urban matrix, featuring the perforated architectural fašade. The transparent glass screen, separated from structural holes, is only to maintain the internal conditions, not to serve as a window. The circular cell placed diagonally reduces weight of a rectangular tube, reinforced concrete structure. The cast are made of P.O steel using a laser cutting machine and packed with high strength high flow concrete.
