be 750mm from the side and rear
property lines.

36
Q

Firewalls

A

A fireproof barrier used to prevent the
spread of fire between or through
buildings
Why are firewalls important? Because
when they are built, the building or parts
of the building extends into the setbacks.

37

Keyword: inside/enclosed
Includes services/parking (unlike GFA)

44
Q

Allowable max. TGFA

A

Table VII.1, p.84 of Rule 7 & 8
Format: Number of floors x footprint
Depends on the ff.:
Lot type
Zoning
Use of firewalls

45
Q

Lot types

A

Inside or regular lot
Through lot
Corner lot
Corner-through lot
Interior lot
End lot
Corner lot abutting 3 or more streets etc.

46
Q

BHL

A

Building height limit
Given in Table VII.2 on p.89
Depends on zoning

47
Q

how is building height measured?

A

From established grade line to the topmost
portion of the building
Excludes allowed projections above the
roof, like:
Signage
Masts
Antenna or telecom tower

48
Q

How to establish the grade line

A

Grade line = highest adjoining sidewalk or
natural grade line
If grade is sloping:
If less than 3 meters diff., take highest grade
If more than 3 meters diff., take the average

49
Q

how to establish top of building

A

If roof is flat, top = rooftop
If roof is sloping, top = middle of roof
height

50
Q

height limit on projections

A

Towers, spires and steeples
If made of combustible materials, 6.0m above
BHL
If made of incombustible materials, limited
only by structural design

51
Q

building height + RROW

A

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
0-3m RROW: 2.0 storeys or 6.0m
Only exceptions: PUD

52
Q

Other considerations:BHL

A

The volume/bulk being constant, a
building with a lesser PSO or AMBF may
be built higher than one with a higher
PSO.
A building with a greater TGFA
requirement may be built higher than one
with a lower TGFA requirement.
A building with a higher FLAR
designation may be built higher than one
with a lower FLAR designation.
Lots facing a wider RROW may become
the site of a taller building than a lot
facing a narrower RROW.

53
Q

Fractions in computations - parking

A

When computing for parking slots, a
fraction of 50% or higher shall be
considered as one slot.
In all cases, at least one slot shall be
provided unless otherwise allowed.

54
Q

off site parking lots

A

If a multi-floor parking garage is located
within a 200-meter radius of the building,
20% of the required parking provisions may
be served the multi-floor parking garage.
Reserved or leased parking slots may also
serve the parking requirements if:
The slots are in a permanent parking building
and not in a vacant parking lot.
The said parking building is:
Not more than 100m away, if residential
Not more than 200m away, if commercial

55
Q

front yards as parking

A

Not allowed for the following:
R2 Maximum
R3 Maximum
GI
C1, C2 and C3
50% of front yard may be used as parking
for R2 Basic and R3 Basic

56
Q

A

sanitation
At least one sanitary toilet and adequate
washing and draining facilities
foundation

stairs
Minimum width: 750mm
Maximum riser: 200mm
Minimum tread: 200mm
entrance & exit
At least one entrance, and another one for
exit

57
Q

development controls

A

TLA = Total lot area
PSO = Percentage of site occupancy
The part of the lot occupied by the building
(A.K.A. building footprint expressed in %)
TOSL = Total open space within lot
The part of the lot NOT occupied by the
building
TLA = PSO + TOSL
USA = Unpaved surface area
The portion of the open space that is unpaved
ISA = Impervious surface area
The portion of the open space that is paved
Since “open space” = TOSL,
TOSL = USA + ISA
MACA = PSO + ISA
Hence, TLA = MACA + USA
AMBF = Allowable max. building footprint
Footprint expressed in square meters
GFA = Gross floor area
Total enclosed floor area (including balconies)
Excludes the following enclosed areas:
Parking, services, utilities
Vertical penetrations in parking floors if not used for
residential or commercial purposes
Balconies exceeding 10sqm, uncovered areas, fire escape
structures, etc.
TGFA = Total gross floor area
Includes all enclosed floor areas, no exceptions
AMVB = Allowable max. volume of
building
OFB = Outer faces of the building
FLAR = Floor and lot area ratio

58
Q

building bulk

A

A volume quantity
In the simplest sense,
Building bulk = Footprint x Height
However, the Code prescribes several
different methods for determining this
quantity

59
Q

building bulk by AMBF projection

A

Determine the AMBF
Determine the BHL (in meters)
AMBF x BHL = Building bulk

60
Q

building bulk by FLAR

A

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.

Bulk = Footprint x Height
To get footprint:
FLAR x TLA = Total floor area
Total floor area/Number of storeys = Footprint
Hence:
[(FLAR x TLA)/number of storeys] x BHL

61
Q

building bulk by AMVB

A
  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.
62
Q

Other development controls

A

AMBF (Allowable maximum building
footprint)
= TLA – Yards/setbacks + Additional area due to
firewalls
PSO = AMBF / TLA
GFA = TLA x FLAR
TGFA = GFA + Non-GFA – Courts
