While building, water is mostly underrated by many builders reason being that they believed that water should be a normal something, believe me, if your building projects must be successful you must look for a means to make water available for site workers so as to avoid delay of work or wastage of materials due to water shortage.

Many builders already know this facts as well, if they don’t have money to seek borehole they will dig soak away first in form of well (reservoir) which is  advantageous because the sand gog out will be used for filling and this idea will save you from the cost of renting Gen to pump water anytime you want to work.


Foundation Cost

After a building plan is set up, we move to start building. Setting a strong and well-constructed foundation for the house is the first stage of building. The foundation involves flooring and soak away too. Here, the ground is dug well so as to hold the house firmly.  Foundation and flooring can be so expensive but as i earlier mentioned it also depends on the city, materials and the building season.

Cost Of Building From Ground Floor To Lintel Level

After the foundation has been laid, the next stage is building the structure of the planned design from the ground floor to lintel level. Here, we have the living room, kitchen, 2 or 3 bedrooms, toilet, bathroom and dining room. Measurement is very important at this stage. This is very necessary for sizes of rooms, doors and windows. In determining the cost of this stage, one must consider the number of blocks, sand, cement and lintel casting. This stage is constructed from the ground floor to the lintel level.
