• TLA

  Total lot area

  = width x depth/ width x length

  TLA = PSO + TOSL
• PSO

  Percentage of the site occupancy

  part of the lot occupied by the building (a.k.a. building footprint expressed in %)

  = AMBF/TLA x 100%
• TOSL

  Total open space within lot

  the part of the lot not occupied by the building

  = Y1 + (Y2+Y3+Y4) (For R-1)

  = USA + ISA

  = TLA - AMBF
• USA

  Unpaved surface area

  the portion of the open space that is unpaved

  = minimum value
• ISA


  Impervious surface area

  the portion of the open space that is paved

  = maximum value
• MACA

  Maximum allowable construction area

  = PSO + ISA

  Hence, TLA = MACA + USA
• AMBF

  Allowable maximum building footprint

  footprint expressed in square meters

  = (w-setbacks) x (d-setbacks)
• GFA

  Gross Floor Area

  the total floor space within the perimeter of the permanent external building walls

  shall also include building projections which may serve floors or platforms that are directly connected to/ integrated with areas within building/structure (e.g. balconies)

  = TLA x FLAR
• GFA excludes:

  (a). Covered areas used for parking and driveways, services and utilities;

  (b). Vertical penetrations in parking floors where no residential or office units are present; and

  (c). Uncovered areas for helipads, air-conditioning cooling towers or air-conditioning condensing unit (ACCU) balconies, overhead water tanks, roof decks, laundry areas, cages, wading or swimming pools, whirlpools or jacuzzis, terraces, gardens, courts or plazas, balconies exceeding 10.00 sq.m, fire escape structures and the like.
• TGFA

  Total gross floor area

  the total floor space inside the building primarily consisting of the gfa and all other enclosed support areas together with all other usable horizontal areas/surfaces above and below established grade level that are physically attached to the building/s
• TGFA includes

  (a). Covered areas used for parking and driveways, services and utilities; it specifically excludes provisions for courts above grade level;

  (b). Vertical penetrations in parking floors where no residential or office units are present; and
• TGFA includes

  (c). Uncovered areas for helipads, air-conditioning cooling towers or air-conditioning condensing unit (ACCU) balconies, overhead water tanks, roof decks, laundry areas, cages, wading or swimming pools, whirlpools or jacuzzis, terraces, gardens, courts or plazas, balconies exceeding 10.00 sq.m, fire escape structures and the like.
• TGFA Includes

  (d). Other building projections which may additionally function as floors or platforms if properly reinforced, e.g., the top surfaces of roof extensions/eaves, sun breakers, large roofed or cantilevered areas such as porte cocheres, canopies and the like
• Allowable maximum TGFA

  Table 7.1, rule 7

  format: number of floors x footprint

  depends on the ff: lot type, zoning, use of firewalls
• AMBV

  Allowable maximum volume of building

  = BHL x AMBF
• OFB

  Outer faces of the building
• FLAR

  Floor and (to) lot area ratio

  = GFA/TLA

  •For example, a FLAR designation of 1.50 means that a lot measuring 100 sq.m may accommodate a building whose total floor area is 150 sq.m

  • In a way, FLAR tells us how many lots can fit inside the building.
• BHL

  Building height limit

  given in table 7.2

  depends on zoning
• HOW IS BUILDING HEIGHT MEASURED?

  • From established grade line to the topmost portion of the building.

  • Excludes allowed projections above the roof like: •Signage

  •Masts

  •Antenna or telecom tower
• ESTABLISHING THE GRADE LINE

  • Grade line= highest adjoining sidewalk or natural grade line

  • But if grade is sloping:

  • If less than 3 meters diff., take highest grade

  • If more than 3 meters diff., take the average
• ESTABLISHING THE TOP OF BUILDING

  • If roof is flat, top= rooftop

  • If roof is sloping, top= middle of roof height
• HEIGHT LIMIT PROJECTIONS

  • Tower, spire and steeples

  • If made of combustible materials, 6.0m above BHL

  •If made of incombustible materials, limited only by structural design
• above 3m, get the average

  
• BHL + RROW

  • The RROW width also dictates the BHL:

  • 6-7m RROW: 3.0 storeys or 9.0m

  • 4-5m RROW: 2.5 storeys or 7.5m

  • 3.0m and less RROW: 2.0 storeys or 6.0m

• PARKING REQUIREMENTS

  • Given in Table VII.4

  • Based on occupancy and lot/ floor areas
• SAMPLE PARKING REQUIREMENTS- hotels


  • If highly urbanized, 1 slot for every 3 rooms

  •If not, 1 slot for every 7 rooms

  •2 tourist bus parking slots

  • 1 loading slot for articulated truck
• SAMPLE PARKING REQUIREMENTS - churches


  • For every 50 sq.m of congregation area, provide:

  •1 car slot

  •1 jeepney slot
