a) Exterior open spaces: In residential buildings exterior open
spaces shall be provided at the front. sides and rear of any building within the plot
boundaries depending the residential schemes, namely detached building, semi-detached
building or row housing scheme as under:
(i) Front open space
shall be as follows:
Depth of the plot in
mtrs |
Minimum set back from the boundary of the plot in
mtrs. |
| Up to 18 |
3.0 |
| Above 18 and not
exceeding 27 |
4.5 |
| Above 27 and not
exceeding 36 |
6.0 |
| Above 36 and not
exceeding 45 |
9.0 |
| Above 45 |
12.0 |
(ii) Rear open space: Every building
shall have rear set back of minimum 3.0 mtrs. width and in case of corner plot less than
300 sq. mtrs. in area the rear set back shall be of minimum 2.4 mtrs.
(iii) Side open space: Every semi detached and
detached building on plots of 300 sq. mtrs. area and above shall have open space of 3 mtrs
width at one side.
In case of corner plots of area less than 300 sq. mtrs., the side setback shall
be minimum 1.2 mtrs. up to 40% of the buildings length towards the side abutting street.
(iv) In the case of semi-detached buildings the habitable rooms shall abut
either an exterior open space or an interior open space.
(v) In the case of a corner plot including a row housing the side open space
shall be provided towards the longer side of the site.
b) Interior open space-Habitable rooms not abutting either the
front, rear or side open spaces shall abut an interior open space the area of which shall
not be less than 9.0 sq. mtrs. with a minimum width of 2.4 mtrs. Chhajja projection up to
0.45 mtrs. width shall be allowed on the interior open space at lintel level only.
c) Ground coverage-In case of residential building on plotted
development, the maximum covered area on each floor shall be
as follows:
Size of the plot in sq.
mtrs. |
Covered area on each floor in
percentage of the area of the plot |
| 1. Up to 250 |
60 |
| 2. Above 250 and
not exceeding 500 |
50 |
3. Above 500 and
not exceeding
1000 |
45 |
| 4 Above 1000 |
35 |
NOTE-A proportional
increase in permissible covered area on ground floor shall be allowed to the proportional
increase in plot size as mentioned above. For example the permissible covered area on
ground floor for the plot size of 270 sq. mtrs. shall be as follows:
60 per cent of 250 sq. mtrs. plus 55 per cent of 20 sq. mtrs. = 161.0 sq. mtrs.
setback will be the determining factor for ground coverage.
d) Barsati-In the case of residential buildings where a barsati is
allowed, the total area to be covered by the barsati excluding the staircase shall not
