Effective space ordering, characterize by small varies spaces, is very crucial on apartement design. Apartement design which has huge numbers of floors will eventually reconsider how to choose structures types to achieve the most effective solution on space ordering. Therefore, shearwall structure is one of the alternatives on apartement design. Shearwall sructure study main pupose is to analyze the effective values of apartement small space which has been presented in the architecture seminar subject. Writer choose Nirvana apartement of Kemang, Jakarta, due to its shearwall structure system. The study mainly done by analyzing effective values (standard furniture, adaftive, space layout) as parameters to acknowledge the effective values of small spaces. Nirvana apartement has a long croos sectional area which makes the building slim with 14 levels of floors. Shearwall structure has been planted as the base structure due its supporting values and safety reason local earthquake.
