KLB (Koefisien Lantai Bangunan)
PRACTICE & STANDARDSintermediateKLB
Definition
Koefisien Lantai Bangunan — the floor area ratio (FAR), representing the total permitted floor area as a multiple of the site area. A KLB of 3.0 on a 500 m² site allows a maximum total floor area of 1,500 m², achievable as a three-storey building with full KDB coverage or a taller building with a smaller footprint. KLB and KDB together control both the density and the vertical distribution of development on a site.
Example
A high-rise site in Jakarta's CBD may carry a KLB of 10 or higher, permitting skyscrapers whose total floor area is ten times the land area, while a low-density residential zone may limit KLB to 1.2–1.8, effectively preventing development beyond two storeys.
