I don't know if the roof you are talking about is like a pavilion or a flat ridge with four slopes, but in either case, reinforced concrete can solve it. I know nothing about it. I suggest you consult someone who is engaged in structural design or construction in this field and tell them your thoughts. It is not difficult to solve.

This kind of house can be solved without frame structure and brick-concrete structure, but it should have ring beams and constructional columns.

As for the cost, it depends on the foundation form and size, wall thickness and decoration standard of your house. Because you also mentioned the glazed tile roof, it is difficult to estimate. The scalability is large, which may be between 550~800 yuan/㎡. I don't know the situation, just say it according to my own understanding, please refer to it.
