lndoor landscape plays important roles in the environmental improvements of inner building and play leading roles in offering green space to urban communities. as proffessionally part of technically construction, constucting indoor landscape, we have to frame the standard of materials and the standard of materials and the construction expanses because the demand of indoor landscape have risen increasingly. Especially, indoor landscape have kept in being paltry and unproffesionalty under the present condition of no standards about the estimation of proper construction expenses, Also, when Unit Cost chart is made, there are no indicators or specific standards that evaluate unit price. So this study carried out to suggest the evaluating standards of plantings pen some areas. It can be the basis work of the making out the proper constructional expenes The progresses and details of this study were the followings -first, the list of indoor plants and the standard of planter were suggested, through case study of indoor landscape and blue-drawings. -second, the quantity of planting materials according to each standardized planter was suggested through the theoretical and numeric methods, the existed unit cost charts and survey of several indoor landscapes -third, the quantity of typical planting materials according to each standized planter was also suggested. The result of this study were the followings. -the quantities per unit area of indoor ground cover flowing plants were 176/ m' in case of 3 chi planter of the type of upper growing, 127 I m' in case of 3 chi planter of the type of side growing. They were 94/ m2, 51/ m2, 38/ m2, 28/ m2 in order 4 chi, 5 chi, 7 chi, 7 chi planter of type of upper growing. Also they were found out 67/m2, 32/ m2, 24/ m2, 18/ m2 in order 4, 5, 6, and ?chi planter of the type of side growing. This study have several limits suggesting only the quantity of plants per unit area, to make out unit cost. llereafter this study will be developed to suggest the unit standard and unit cost of the other materials besides planting materials in indoor landscape. And the labor cost per unit materials will be developed through the next studies on the basis of the result of this study.
