  b)     Define ‘Aspect’ and ‘Prospect’ and give one example of each.                                      04M
         Aspect- Different rooms of the building are placed and located according to the                   01M
         functional utility in such a way that maximum advantage from natural elements like sun,           Each
         wind can be obtained. Sunlight provides the illumination inside the rooms and there is no        define
         need of artificial lighting. It also creates pleasant a cheerful atmosphere inside the room.      and
         For example: kitchen is placed to the east direction as morning sun rays kill bacteria and       01 M
         germs. Bedroom is provided towards west as in summer there is plentiful of breeze and           example
         evening sun removes dampness.                                                                     each
         Prospect-Prospect means taking advantage of desirable views available from windows,
         doors, balconies, terraces of features outside the building such as garden, lake, sea, river,
         hill, etc. and blocking undesirable views such as slum area, gutters, garbage dump,
         railway track, etc. by providing blank walls.
         For example: If there is lake towards east side we can provide balconies, terraces and
         windows towards that direction and if there is slum area towards west direction we can
         provide a blank wall towards that direction.
  c)     State minimum dimensions required for following:                                                 04M

Q. 3   Answer any Three:                                                                                    24M
 a)    Define the following terms and state their values for the residential building in Q.2.               08M
          1) Built up area-It is the area covered by all floors of the building. It covers everything       01 M
              under roof but excludes balconies, staircases, etc. It is area covered by building on all
              floors. It includes floor area of all rooms plus wall thickness.
              Built up area for Q.2- 7.6 * 8.9 = 67.64 sq. m.                                               01 M
          2) Carpet area- this is the floor area of the usable rooms at any floor. Actually it is the
             area where carpet can be laid. It excludes area of sanitary accommodation, verandah,
             corridor and passages, kitchen and pantries, stores, entrance and porches, staircase and        01M
             mumties, shafts for lifts, barsaties, garages, canteens, air conditioning ducts and plant
             room
             Carpet area for Q.2-
             Carpet Area = Built up Area- Area of W.C., Bath & Kitchen & Verandah
                           = 67.64 – (1.2*1.0 + 2.1*1.2 + 3.7*3.5 + 3.7*1.8)
                           = 67.64 –(1.2+2.52+12.95+6.66)
                           = 67.64-23.33                                                                     01M
                           = 44.31 Sq. m.
          3) Plinth area- the area of the building including area of all units with wall thickness at
             plinth level is called as plinth area. This is built up covered area measured at the floor      01M
             level of the basement or any storey.
             Plinth area for Q.2-
             Plinth Offset Assumed = 0.05 m
             Plinth Area = (7.6+0.05+0.05) * (8.9+0.05+0.05)
                           = 7.7 * 9.0
                           = 69.30 Sq. m.                                                                    01M
          4) FAR- it is defined as ratio of total built up area to the area of plot. It is also called as    01M
             floor space index (F.S.I)
             FAR for Q.2-
             Assumed Side Margins on all sides = 3m
             Therefore, Plot Area = (7.6+3+3) * (8.9+3+3)
                                    = 13.6 * 14.9
                                    = 202.64 Sq. m.
             FAR = Total Built up Area/Total Plot Area
                    = 67.64/202.64
             FAR = 0.334                                                                                     01M

                 d) Scales for site plan-1:200, 1:500 or 1:1000
         ii) Define vanishing point. State and define the types of perspective drawings based                 04M
         on the number of vanishing points.
         Vanishing point- The point in which system of parallel lines of object inclined to picture            01M
         plane appears to converge is called vanishing point. It is the point at which all lines              define
         converge.                                                                                             and
         Types of perspective drawings-                                                                       03 M
             a) One point perspective-It is also called as parallel perspective. It consists of only          types
                 one vanishing point from which lines originate or radiate. One or more faces are
                 parallel to the picture plane; these drawings are useful for road views, railway
                 track, row-housing scheme, interior designing, etc.
             b) Two point perspectives- The viewer is at an angle to the building or space in front
                 of him. There are two vanishing points for all lines of object or building, one right
                 and one left. This is most general case of perspective drawing.
             c) Three point perspective-This type is important when height or depth is prominent.
                 Picture plane is tilted so that all three sets of planes and lines are at angle to picture
                 plane. There are three vanishing points, two on horizon and one above or below the
                 horizon. This type of drawing is used to show skyscrapers or view from top of very
                 tall building or view from aero plane.
Q No.4   Answer ANY TWO :                                                                                     16M
  a)     Define the following and state their types:                                                          08M
             i) Privacy ii) Circulation. Give example of each type.
             i) Privacy-Privacy means isolating building or room from surrounding. It is of two               04M
                 types.
                 a) Internal privacy-It means isolating room from adjacent rooms or
                      corridor/passage by proper placement of rooms, doors, and passage.
                      e.g. Use of screens, partitions, proper arrangement of furniture increases
                      internal privacy.
                 b) External privacy- It means isolating building from adjacent building, roads,
                      etc. It can be achieved by providing compound wall, planting trees around
                      building, creepers on fencing, providing open space around building, etc.
                      e.g. Proving compound wall of height 1.35m-1.5m.
         ii)     Circulation-It means movement from one place to another. It is of two types:                 04M
               a) Horizontal circulation- It refers to movement of person from one room to
                  another with the use of doors, corridors, passages, etc.
                  e.g. Passage can be used to go from one classroom to another.
               b) Vertical circulation-It refers to movement of person from one floor to another
                  with the use staircase, lift, ramps, escalators, etc.
                  e.g. Generally staircase and lifts are provided in building for vertical circulation.
