Which is more expensive, a glass elevator or a concrete elevator

Old homes without shafts to add an elevator to the 8-story building as a base, the glass will cost about 430,000 yuan, and the concrete will cost 3 to 10,000 more.

Glass elevator shafts have the advantage of being aesthetically pleasing and not easily affecting the lighting of the lower floors. However, installing a glass elevator shaft is more expensive to maintain later than a concrete structure.
