In the design concept of the whole house, safety is the primary consideration. The hard installation part needs to ensure the stability and durability of the structure, and the use of environmentally friendly and non-toxic building materials to ensure that there will be no threat to the health of the occupants. For example, the floor material should be non-slip and fireproof, the wall paint should be harmless and durable, and the layout of the wire and pipe should comply with safety regulations. Through scientific construction and material selection, hard installation can effectively protect the life safety of family members.
