BUILDING DESIGN

FEATURES that you’ve always wanted in your home

Abuilding should be planned to make it comfortable, economical and to meet all the requirements. The planner should be to attain maximum convenience with the limited money available. Functional utility, cost, habits, taste, requirements etc., should be considered by the planner. Circulation area should be minimum possible without effecting other requirements and convenience. To start with all the requirements should be collected and then planning should be taken up and a number of alternative proposals prepared and comparing their advantages and disadvantages the best one should be adopted. For private buildings each inidividual has different views, opinions and likings, and the engineer and architect shall have to satisfy the owner, for which a number of sitting will be required to finalise the Plan.

Area, Shape, size and height all influence cost apart from cost of construction and materials. A square plan is cheaper than oblong. The perimeter of walling of a square building me be 15% to 25% less than a rectangular building.

A square building of size 10m x 10m has area of 100 Sqm. and perimeter of 40m, a rectangular building 20m x 5m has area of 100 Sqm. and perimeter of 50m, both have same area but the rectangular one has longer walls.

It is therefore desirable to plan or design a building as far as possible square. Moreover a square house being compact has many other advantages. A compact house is cooler in summer and warmer in winter. Construction of roof and other parts of square building is simpler and square house gives a better view. A barrack type long building is exposed to heat waves during summer and co cold waves during winter, and is exposed to sun and rain.

For the same area of the building the bigger the size of rooms and lesser is the cost, the smaller the size of rooms the greater will be their numbers and hence more walls and costlier. If possible, number of rooms should be reduced and the size of rooms be made bigger, to economise the cost. But the size of rooms will depend on the requirement and the purpose for which they are meant and this aspect of economy cannot be applied in general.

Smaller buildings cost more in proportion than bigger one of the same type, and detached building cost more than semi-detached. Bungalows are costlier than storeyed house of the same capacity. A double storeyd building is economical, the upper storey is cheaper than the ground storey. It is better to provide bed room in the upper storey. Upper storey rooms are airy and better ventilated.
