Aspect Aspect isthe positioning of rooms in buildings with respect to 4 directions in such a way that the occupants of the building would enjoy the natural comforts like sunshine, breeze, scenery etc. to the maximum possible extent. A room receiving light and air from any particular direction is said to have the aspect of that direction.

A beautiful landscape consisting of garden or hill as viewed from the window or an external door is a good prospect. However it may be necessary to conceal some of the objectionable views on religious or social considerations. This may be achieved by planning a dead wall in that direction butt in doing so, one may be required to compromise with some natural gift of sunshine and ventilation.
- 9. Privacy Privacy isan important part of building planning. Privacy may be from one part to other of the same building or it could be from neighboring buildings, streets, etc. In residential buildings, every room should have certain privacy which can be secured by careful planning the entrance, path-ways, and drives. Proper grouping of rooms, good positioning of doors and windows, lobbies or screens can give required internal privacy. Toilet rooms, bedrooms, w.c., urinals, should have absolute privacy.

Circulation between rooms of the same floor is called horizontal circulation like – passages, corridors, halls etc. Circulation among various floors is known as vertical circulation, like – Stairs, lifts. horizontal circulation should be independent, short, and straight and should not invade the privacy of any room. All the passages should be well ventilated and lighted. Stairs should also be well lighted and ventilated and properly planned in regard to width, rise and tread. stairs should not have wider steps.
- 14. Roominess Roominess isobtained by getting the maximum benefit from the minimum dimension of a room without cramping of the plan. By using every nook and corner of the building to the maximum advantage roominess is derived. In residential buildings, considerable storage space is required for various purposes which are provided by making space for wall cupboards, lofts, wooden shelves etc.
- 16. Grouping Grouping meanssetting different rooms of a building according to their inter- relationship of invitation and transition. The rooms are arranged in the layout in a proper correlation of their functions and in due proximity with each other. Grouping of a residential building The dining room should be close to the kitchen. The kitchen should be kept away from the main living room Main bedrooms should have independent and separate access from each room towards the sanitary units. Bath and W.C should be approachable directly or through rooms like drawing, living, stair, dining, etc. In an office building, hospitals etc. the administrative department should be located centrally for convenience and economy of services.
- 19. Sanitation Sanitation ofa building not only associates with urinals, bath-rooms, wash- basins, sinks but also the overall lighting and ventilation. All the parts of a building should have well lighting and ventilation to maintain good hygienic conditions. This could be done with natural way or in an artificial way (air condition). Necessary provision to facilitate the cleaning of the building should be installed. Washing closet, lavatories, urinals, bathrooms like sanitary conveniences should be installed adequate in number in relation to the occupant load.
- 21. Flexibility Flexibility meansplanning the rooms in such a way which though originally designed for a specific purpose, may be used for other purposes also when desired. For designing of houses for middle-class families or other buildings where the economy is the main consideration flexibility should always be considered. If large space needed in a certain time in a house to accommodate the gathering, it can be obtained by removing a removable partition wall or curtain between the drawing room and dining room. Alternatively, open yard, garden, or verandah can also be provided.
- 22. Economy The economyis a major factor in building planning. To fit the proposed scheme within the limitations of the resources and funds certain alteration and omissions in the original plan have to make. But while considering the economy, the required strength and durability of the structure should not be compromised. Some simple economy achieving approaches in buildings are – Simple elevation, dispensing of porches, lobbies, steeper rise to the stair, wider steps in stairs. reducing the storey height to bare-minimum standardization of sizes of various components, and materials.
- 24. Elegance The eleganceis the overall effect produced by elevation and general layout of the plan of a building. To get a good elegance of a building it is better if elevation is developed first and then the plan is adjusted accordingly.
