▪ TLA =
PSO + TOSL
TERMS DEFINED
▪ USA = ___

▪ ISA = ______
▪ The portion of the open space that is paved
▪ Since “open space” = TOSL,
Unpaved surface area
Impervious surface area
▪ TOSL =
USA + ISA
TERMS DEFINED
▪ MACA = ______
▪ Hence, _______
PSO + ISA
TLA = MACA + USA
MACA
▪ Note: MACA stands for Maximum Allowable Construction Area
TERMS DEFINED
▪ AMBF = _______
▪ GFA = ______
▪ Excludes the following enclosed areas:

▪ Vertical penetrations in parking floors if not used for residential or
commercial purposes
▪ Balconies exceeding ____, uncovered areas, fire escape
structures, etc.

TERMS DEFINED
▪ TGFA = _____
▪ AMVB = ____
▪ OFB = _____
▪ FLAR = _____
Total gross floor area (▪ Includes all enclosed floor areas, no exceptions)
Allowable max. volume of building
Outer faces of the building
Floor and lot area ratio
BUILDING BULK
▪ A volume quantity
▪ In the simplest sense,
▪ Building bulk = ______
▪ However, the Code prescribes several different
methods for determining this quantity
Footprint x Height
Method 1 for Determining Buildign Bulk
METHOD 1:
AMBF PROJECTION
▪ Determine the AMBF
▪ Determine the BHL (in meters)
▪ AMBF x BHL = Building bulk
Method 2 for Determining Buildign Bulk
METHOD 2: FLAR
▪ FLAR : Floor to lot area ratio
▪ Total floor area / lot area
▪ For example, a FLAR designation of 1.50 means that a
lot measuring 100sqm may accommodate a building
whose total floor area is 150sqm.
▪ In a way, FLAR tells us how many lots can fit inside the
building.
METHOD 2: FLAR
▪ Building bulk = Footprint x Height
▪ To get footprint:
▪ FLAR x TLA = Total floor area
▪ Total floor area/Number of storeys = Footprint
▪ Hence, building bulk is equal to:
▪ [(FLAR x TLA)/number of storeys] x BHL
*Check the extension of the Table, Understand this method further
Method 3 for Determining Buildign Bulk
METHOD 3: AMVB
- AMBF x BHL = initial AMVB (“prism”)
- Superimpose the angular plane originating from
the RROW onto the “prism”
▪ Angular plane: a plane originating from the RROW that
establishes the outer limit for walls and building
projections. - Use the angular plane to reduce the volume of
the prism. This is the AMVB.
OTHER FORMULAS
▪ PSO = ____
▪ GFA = _____
▪ TGFA = _____
AMBF / TLA
