[Ministry of Housing and Urban-Rural Development: Promote the construction of good houses from good standards, good design, good materials, good construction, good luck, maintenance of the whole chain, and the whole life cycle] On September 18, Chen Shaowang, spokesperson and deputy minister of the Ministry of Housing and Urban-Rural Development, said at a press conference of the State Council Information Office that the key to improving the living standards of the people during the "15th Five-Year Plan" period is to build good houses. Promote the whole chain and life cycle with good standards, good design, good materials, good construction, good luck and maintenance. In response to complaints from the public about low floors, we raised the floor height standard from the original 2.8 meters to 3 meters; in order to solve the problem of elderly people going up and down stairs, the new standards require the installation of elevators in residences on the fourth floor and above; in response to the issue of child safety protection, the height of guardrails in all high-altitude areas such as balconies and verandahs has been raised to no less than 1.2 meters.
