House construction: Budgeting and Planning
PART I
Budgeting and planning are two important steps towards construction of any building. In commercial constructions, the client or the owner is getting all kind of technical and commercial advices from the expert consultants as paid services. But for own villa (residential house) construction, 90% of the planning and design has to be done by the house owner himself. Otherwise the house would not look like the one, your family members wanted it to be.
The assistance of the consulting engineer shall be limited because he cannot go in deep to your psychological requirements and your financial abilities. You may not succeed in conveying the same to your consultants due to various reasons. So you will never get a final design as you have dreamed!
To avoid this, it is better you should also learn something in designing and budgeting. My website (www.keralaengineer.com) will help you to achieve this goal to a certain extend.
In planning, your initial job is to collect available data in house construction industry. From friends and relatives these data should be collected. Also by the use of telephonic conversations and by reading periodicals more ideas shall be gathered. This information shall be recorded for future references. This will help you to make better decisions to get the job done very easily.
Cost of materials and local labour charges should be noticed and this will help you in future to decide how to execute the work. The maximum usage of locally available materials shall help you to bring down the cost. More over as per baubiology specifications, this will help in saving our nature also.
The fund you can mobilize has to be calculated with details. It has to be written down for better clarity. The available amount of Bank loan has to be worked out separately after consulting with one or two Banks. Better and for safer side, consider only 75% of the bank loans or other personal loans for the budgeting purposes.
The next step is some homework and this has to be done along with your family members also. A detailed discussion has to be initiated where the requirements or facilities will be in put against the budget provisions. For this you should have a minimum knowledge of the cost of construction per Square foot or Square metre in your area. The rate of construction cost per square feet or Square Meter area of the type of building you are looking for has to be ascertained for your location. Normally the rate shall vary from Rs.600 to Rs.1200 per sqft. Rs.600/- is applicable for cost effective building construction and it can go upto Rs.1200/- per sqft for a posh style building with marble or vitrified tiles of good quality.
A normal rate of Rs.900/sqft can be considered for your planning purposes. If your budget is 10 Lakhs rupees, you can construct a building of 1111 sqft (1000000/900=1111).
Kindly remember the following factors which are directly related to the total cost of construction (square feet rate).ie. the following items add cost to the square foot rate.
a) The number of toilets and the location of toilets.
b) The room sizes greater than 12 ft (360 cm). New beams need to be inserted will increase the cost.
c) Staircase rooms will add the cost of construction, if you are not constructing at least two bedrooms in the first floor.
d) Sloping roofs
e) The excess number of big windows, which we will never open for ventilation. As per norms 10% of opening is required for sufficient light and ventilation.
1 Meter = 3.28 Ft
1 SqMetre = 10.76 SqFt
