Construction cost estimate required

I am planning to build school building in some rural area. Total rooms will be 8 size 15*18 foot and have 7 foot of shade in front ofall rooms. Please guide me for estimated cost.Thanks…

As per your proposal of 8 rooms with the size of 15' x 18', your building measurement will come out around 120' x 18. If you add the 7' of verandah too then it will be 120' x 25'. Total covered area will be approximately 120 * 25= 3000 sqft. If you go for a normal construction in brick structure yourself then it should not cost you over 1300 Rs/sqft. If you plan to add some concrete pillars in the structure for strength then add another 50 -75 Rs in above estimate. This estimate includes RCC slab. If you want to further minimize the cost you can go for Izhar's pre fabricated slabs.

Other than the structure if you need to build a boundary wall, it will cost you at the rate of 120 to 150 rs / sqft(of the boundary wall) including material labor and plaster.
