Covered area per sqft rate of house construction GREY STRUCTURE


covered area

Difference in covered area will affect the cost of the house. There is this common misconception that if the size of the house or the covered area of the house is same, the cost incurred on the house will be the same.  For instance in our latest grey structure covered area per sqft cost article/video we took 10 Marla home as an example with 3400 sq ft area. Sometimes the covered area can vary because of owner’s demands and requirements for instance if a person wants to construct three story house the covered area of that house will increase to 4200 sq ft 4500 sq ft or even more, similarly if a person constructs a house on a single storey the covered area of that house will be lesser than 3400 sq ft. That does not mean that the cost of grey structure will be same for a house with the covered area of 4300, 3400 and 2800 respectively. The main reason for this is that there are some costs that remain constant no matter what your covered area is. For instance the costs that remain constant are as follows:

Complete boundary wall of the 10 Marla plot

covered area per sqft rate

UGWT (underground water tank)

Septic Tank

Sewerage system of the complete house

Floor PCC of the floor outside the house such as side passage, garage and ramp

Parapet wall, terrace parapet wall

Final water proofing of the roof and Overhead water tank.

These are the costs that remain constant whether you build a single storey home or a double or triple storey home. For instance if the cost of these things is Rs 100 and we divide that cost with covered area of 2400 the amount will be more than if we divide that with 3200, it will be even less if the covered area is more than that. All the costing done by us has been on a standard 10 Marla home with a covered area of 3400 sq ft. If the covered area of the house is more the cost of the house will drop and if the covered area of the house is relatively less the cost of the house will increase.

Many of us think that if we decrease the covered area of the house we can save money of the bricks and steel that wasn’t used due to decreasing the covered area. It does not happen like that. After constructing a full ground floor we try to save covered area on the first floor by adding open areas and front terraces and to cover that we add pergolas and design elements. The cost incurred in adding these design elements are more than the cost we save in form of bricks and steel by reducing our covered area.

  Here we would like to add that if the covered area of a 10 Marla home is 3400 sq ft the cost of the house according to our latest grey structure cost Nov 2019 would be Rs 1419/- sq ft for a premium plus complete grey structure without any compromise in the quality of any type. Similarly if the covered area of the house is less than 2900 or 2800 sq ft than the cost of the house may increase by Rs 200 to 250 /- sq ft. If the covered area increases to 3600 or 4000 sq ft than the cost may decrease by Rs 50 to 80/- sq ft.

We hope this article has cleared the confusion of covered area and how it effects the costs of the house.

Difference between covered area & land area for per sq ft construction cost


House construction on turnkey contracts is based on per sq ft construction cost which requires covered area according to drawings. All the costing articles & videos of Team Overc’s  are based on covered areas. Clients often get confused in covered area and land area. Today we will explain the difference between covered area and land area and the way to calculate them for per sq ft construction cost.
We will take 5 Marla plot as a sample for this article. Land area is also known as plot area and its dimensions are most commonly 25×45 or 125sq yards. The way to calculate land area is very simple as we multiply the length of the plot with its width and we will get the land area. For instance in this case we multiply 25 by 45 and we get 1125 sqft and that is the land area or the plot area of the house. This figure of land area cannot be used in calculating construction cost of your house.

 

Whereas covered area is the area that is constructed on that land. As you can see in the video, the highlighted area is the open area of the land and will not be considered in covered area as there is no construction done in that area. The area in the middle is the place where the construction will be done. So the land area was around 1125 sqft and if we take out the side that will not be constructed we will be left with around 75% of that which will be 900 sqft this will be the covered area of one floor. If you’re making a multi storey building you can add the covered area of that floor to this 900 sqft for example we the covered area of both floors are same so you add 900sqft of ground floor to 900sqft of first floor and you will get 1800 sqft. This will be your covered area of the house.
In another scenario for instance your covered building is not rectangular. As you can see in the video above the constructed area is in different shape and blocks. In this case it may not be possible for a layman to calculate the covered area. The best way to do the calculation would be to divide your constructed area into different blocks. If your blocks are rectangular or the walls are at 90 degrees only then it is possible to calculate the covered area manually. If in case you’re constructed area is not rectangular or square shape, you will then have to use software such as autoCAD to calculate the covered area of the house.

To calculate the total covered area of this house as shown in the video please take the covered area of block A for instance it is 10×20=200 sqft and then repeat the same formula for block B and C and then add all three total figures to get the total covered area of the construction.
In another case if the house has chamfered corners or any round area in the constructed area. There is no way to calculate the covered area manually. To calculate such covered area you will have to consult a draftsmen or an architect. You can also use software such as autoCAD if you’re fluent in it to calculate the constructed area’s covered area.
We hope that the difference between covered area and land area is now clear and won’t be confusing anymore. Please make sure to use the covered area for your per sq ft construction cost from now on and not the land area.
