Plot Area = (considering 3 m front margin and all other margins as 1.5 m)
= (10.6 + 1.5 + 1.5) x (7.40 + 1.5 + 3.0)
= 161.84 Sq.M
Built Up Area = Area of Block1 – Area of Block2
= (10.6 x 7.4) – (4.3 x 2.3)
= 68.55 Sq.M
Carpet Area = (3.0 x 3.5) + (4.0 x 4.5)
= 28.5 Sq.M
F.S.I. Allowed = 1.0 (assumed)
F.S.I. consumed = Built up area/ Plot area = 68.55/161.84
= 0.423
*(Note- 1 mark each for any four points with correct values)

(d) Explain the importance of Planning Principle ‘Aspect’ and ‘Prospect’ in 08
Building Drawing with their examples.
Importance of Aspect-
1) Different rooms of the building are placed and located according to the 02
functional utility in such a way that maximum advantage from natural
elements like sun, wind can be obtained.
2) The rooms should get enough sunlight and air, during some period of day
as every room has different purpose.
3) Therefore by proper positioning of doors and windows in external walls,
benefits of natural elements can be obtained. It also creates pleasant,
hygienic and cheerful atmosphere inside the room.
4) For example: i) kitchen is placed to the east direction as morning sun rays
kill bacteria and germs, ii) Bedroom is provided towards west as in 02*
summer there is plentiful of breeze and evening sun removes dampness, iii)
Study or dining to the North side to get only diffused light throughout the
day and no heat.

Importance of Prospect-
1) Prospect means taking advantage of desirable views available from
windows, doors, balconies, terraces of features outside the building such as 02
garden, lake, sea, river, hill, etc.
2) It also includes blocking undesirable views such as slum area, gutters,
garbage dump, railway track, etc. by providing blank walls.
3) Therefore by proper positioning of doors and windows in external walls,
prospect can be achieved.
4) For example: i) If there is lake towards east side we can provide balconies, 02*
terraces and windows towards that direction and ii) if there is slum area
towards west direction we can provide a blank wall towards that direction.
*(Note- 1 mark for one example)
Important Note: Student may draw figure to explain the
importance of principle. So give credit accordingly.
i.e. 02 marks for importance, 01 mark for figure and 01 mark for
example.
