Planning to construct a floor on our 10 year old RCC roof house (715 sqft built up area). The house was constructed without any pillars but a proper foundation was laid and walls have no visible cracks. The total space available for construction is around 700 sqft.
My questions are,
1. Does the first floor plan has to be exactly same as ground floor plan as there are no pillars?
2. Can the existing walls take the load if we have the partition walls according to our requirements?
3. Considering that we will be using the new terrace (it will be second floor) for placing an overhead water tank, solar and rest of the space to host any functions, what are the technical difficulties that we may face if we use completely a new plan?
Hoping for some suggestions and thanks in advance

Naveen
