In the first photo you can see the large windows which  are a type of glass which is a technological advance. The metal framing is an advance as well. The lights inside were once not there, they were added when the light bulb was introduced. Each of the buildings' characteristics are a technological advance. For example, the many arches and columns on the building. Other advances would include the materials used on the building such as stone and concrete. On the inside there are many materials such as the tile floor, the paintings on the wall, and the wall material itself. Other technological advances would be the plumbing, electric, and heat/air if there is any in the building.
