I live in South Africa and I've got a fully brick house with a wooden roof structure and tiles on top. I know would like to know, would it be possible, to take of the roof, to increase the height of the walls and to put a reinforced concrete slab on it ? I want to build a balcony on top. Will that work ? what must i look at and how thick must the concrete slab be ? thanks for the help in advance !!

building a new roof
Most of the homes I have seen in South Africa were built with 6" solid concrete block or 6" reinforced concrete block. These could take and extra floor as long as the connections are right.
The key is to put the old and new pieces together and make sure you have good continuity. It is possible your will have to add one course(level) of block to your existing walls before building the next floor - No big deal and it will give you more ceiling height.
It is best to find a local designer that is familiar with the local construction and can look at what you have in the way of an existing structure.
