I intend to construct /extend stair case from 1st floor to
second floor. I have already increases height of mumty by 8.5 ft housing the stair case, but roof of first floor (earlier used as mumty) is still there.
Now how to start ? How to make ramp, steps and one midway platform
may kindly be informed.
What are the stages involved and what sort of TMT bars, concrete strength etc should be used may kindly be informed
