In the third trip, we were more focus on the architecture styles of buildings in Metro Tech. We visited the Offerman building which built by 1890 in Duffield St. The ground floor of the building is used for the retail space and the other floors is used for the loft apartment today. The Offerman House recognized a landmark building right now. It is a kind of Romanesque architecture building, and the design is the symmetry style. Its exterior decorated by limestone, buff-colored brick and soft terra cotta. In the ground floor, each line stone is between the windows, and the arches are decorated above the windows. Also, the windows in the ground floor and arches are different scale. On the left side of the building, the Corinthian order columns is supporting the horizontally lintels in between the double-hung window. We think the window in the retail floor is bigger than others because it could invite people to come inside to visit and shop.

The other things we focus on is the buildings in Metro Tech are changing. The new modern building close to the Offerman house is built with steel and curtain wall. That building is the art work and high-rise building. And based on the map of 1940, we can see many houses and building between Duffield St and Willoughby St. But today, there is only one big masonry building in that block and the JP Morgan Chase takes the entire building. At the left block of the JP Morgan Chase, we still see there are two wood material houses but without people live there.

According all the material we examined in the Metro Tech, we could see there are some old style building renewed and replace for the other stores or apartment, and some building is already gone and built the new style buildings and use new material to instead in some areas. We are glad to find out the cheaper, faster, more convenient material to build the building. We know how to use different material to resolve the heat, light, fire and air problems. But sometime if we destroyed the ancient building, we will hard to rebuild again because of limited material resources and high price.
