There are two floors behind the house in the countryside. How to build a bungalow in front?

1. Re-tamp by layers with lime soil. 300-thick raft foundation, diameter 12, bidirectional arrangement, can meet the requirements of uneven settlement of two-story masonry houses. If the muddy soil of the foundation has been changed, it is no problem to make the ground beam on the foundation. However, the economy of the ground beam is a bit wasteful for the two-story masonry structure, and the general masonry structure is mostly used as a strip foundation under the wall.

2. Mainly pay attention to sewers and pipelines, and also consider the structural stability and the bearing capacity of the first floor. There is also the wind resistance and snow resistance of steel structures. If it is foam concrete, it is ok, but ordinary concrete structure is not. In order to reduce the load on the bottom floor, I am renovating a hotel of more than 2,000 square meters, adding one floor, and the final result is strictly budgeted.
