Duplex empty living room, glass guardrail on the second floor corridor? Is it troublesome to install this kind of glass guardrail? Is the cost high? How safe is it for construction?

This is an effect picture, isn't it? In actual construction, it is best to add a supporting profile in the middle. The black one in the picture is the guardrail handrail, which can be made of solid wood or aluminum profile, but it is at least four meters long in the picture, and there must be splicing in the middle, and then there is tempered glass below, which should be 1.2 meters high and 2.4 meters long. Decorate the shops that make windows, sunrooms and stairs in the city, and the workers will do it.
