PLOT DEVIDATION & MINIMUM ROAD WIDTH

EACH PLOT MUST FOLLOW RULES REGARDING SETBACK, GROUND COVERAGE & FAR INDIVIDUALLY

TWO OR MORE BUILDINGS IN THE SAME PLOT MUST BE 4 METER APART AT FACE AND BACK

INCASE OF ONE COMMON ROAD FOR MORE THAN ONE PLOT MUST BE OF MIMIMIUM 6 METER.

ONLY ONE PLOT WITHIN DEVIDED A LAND COULD HAVE A PRIVATE ROAD OF MINIMUM 3.65 METER

6 M

PLOT

ROAD

3.65 M

SETBACK

SETBACK IS MINIMUM OPEN SPACE INSIDE THE PLOT OR LAND AREA FROM THE BORDER AT FACE (F), BACK (B) & SIDE (S)

CONCEPT OF FACE, BACK & SIDE OF A BUILDING

SETBACK

MINIMUM SETBACK AT FACE:

d is the distance of 1.5 m from building and boundary line

d’ is the distance of 4.5 m from building and the centre line of the road

RC is the distance from boundary line and the centre line of the road

If d > (4.5 - RC) then SETBACK is of d meter , i.e., 1.5 meter

If (4.5 - RC) > d then SETBACK is of (4.5 - RC) meter

GROUND COVERAGE

MAXIMUM GROUND COVERAGE MUST FOLLOW THE FAR CHART

Depends on Factors: Plot Area Purpose/ Uses of building Road width

LAND AREA

BASEMENT AREA

BUILDING AREA

GROUND COVERAGE = BUILDING AREA

MANDATORY OPEN SPACE = LAND AREA - GROUND COVERAGE

50% OF MANDATORY OPEN SPACE MUST BE KEPT WITH GREENERY AND

OTHER 50% OF BARE SOIL TO SOAK RAIN WATER

BASEMENT

Should beProvided with Adequate Light & AirRain water Free Provided with minimum 1 stair from to GF

Basement can be extended up to 50% mandatory open space

Basement Roof can be extended to maximum 1.5m from road level

Could be used only for PARKING SPACE & SECURITY and can get extended roof over it, but

>>The security space could not be concealed with solid wall

>>This roof can be used only for SHEDING GARDENING

FLOOR AREA RATIO (FAR)

FAR =Saleable Area

Land Area 10 katha

Or

669 sq. m

R O A D 30 ft

=> Saleable Area = FAR X Land Area

From CHART( For 669 sq. m)

FAR = 4

Max Ground Coverage = 50%

=> Saleable Area = 4 X 669

= 2696 sq. m

=> Number of Storied = 2696669x0.5

= 8 Nos

MAXIMUM GROUND COVERAGE

MINIMUM ROAD WIDTH

FAR ADVANTAGES

0.05 FAR advantage for every 0.3 m extra road width

0.01 FAR advantage for every 1 m2 open land

Existing Rw 12 mMinm Rw 9 m by FAR

Then, FAR advantage

= 0.05 X (12 – 9) / 0.3

= 0.5

LAND

ASSUMING

Land - 20 katha (1 Bigha)

Land : 20 khata (160’-0”x90’-0”)FAR (floor area ratio) = 4.50Road = 40’-0” (Minimum)Total Floor Area = 4.50 x 20 x 720 = 64800 sft (all floor)Ground coverage = 45%i.e 20 x 720 x 45/100 = 6480 sft (each floor)So, No. of floor : 64800/6480 = 10

i.e (G+10) : 11 storied

A COMPARATIVE ANALYSIS OF FAR & OLD RULE

Assuming Land (160’-0” x 90’-0”) = 14400 sftArea in each floor = (88’ x 82’) + (44’ x 82’)
