TERMS DEFINED ▪ TLA = \_\_\_\_\_ ▪ PSO = \_\_\_\_\_\_ ▪ The part of the lot occupied by the building (A.K.A. **building footprint expressed in %)** ▪ TOSL = \_\_\_\_\_\_\_ ▪ The part of the lot NOT occupied by the building

Total lot area Percentage of site occupancy Total open space within lot

▪ TLA =

PSO + TOSL

TERMS DEFINED ▪ USA = \_\_\_ ▪ The portion of the open space that is unpaved ▪ 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: ▪ Parking, services, utilities ▪ Vertical penetrations in parking floors if not used for residential or commercial purposes ▪ Balconies exceeding \_\_\_\_, uncovered areas, fire escape structures, etc.

Allowable max. building footprint - ▪ Footprint expressed in square meters Gross floor area (▪ Total enclosed floor area (including balconies)) 10sqm

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

1. AMBF x BHL = initial AMVB (“prism”) 2. 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. 3. Use the angular plane to reduce the volume of the prism. This is the AMVB.

OTHER FORMULAS ▪ PSO = \_\_\_\_ ▪ GFA = \_\_\_\_\_ ▪ TGFA = \_\_\_\_\_

AMBF / TLA TLA x FLAR GFA + Non-GFA
