Making..

 I was just trying to see how things would work so I started to make a 1:20 model out of paper and very thin perspex:

 Trying to figure out the measurements and the angles:

 Painting the 1:5 model's glasses (out of perspex) with glass transparent paint:

Interior, painted windows and wooden walls and floor, old looking.

Metallic look using an aluminum tape, modern looking.

Final model out of metal and real glass, painted.

Welded support

Solar film (one way mirror film) added to the glass in order to make the building look very modern from outside.

 

The idea was to show the contrast between an old and a new building. People in my group were trying to show how they were feeling about new buildings and how they were renovating the buildings to answer the need of the society by replacing parts with the new material like steel. The structure of my precedent building is out of metal so I decided to use metal as my material. To show the contrast I used metal for the outside and solar film (one-way mirror film) to make things look modern. I used wood for the inside to cover all the parts in metal and painted windows to give it a feeling of old looking building from inside, the warmth that we all feel by interring an old looking building, brown wooden parts, light playing around with the painted windows and etc. 

For my model I wanted things to be neat, smooth and kinda shinny from outside so I used welding way but I guess I made a mistake and that wouldnt really work very well in real life. The I started thinking maybe I could do a more complex design by designing two layers of walls and windows, the first layer from inside would have bolts and all those construction things to make the building strong enough to hold 5 people in it with some dead loads. From the outside (second layer) there would be a less strong construction just for the view from outside, so very smooth metallic walls with smooth mirror like windows, everything perfect without anything disturbing the shape. In this way the building would be both strong and smooth and neat. for the inside layer I was thinking to choose thick wooden floor and use bolts holding to walls and the metal floor to it. and everything would be built on a bridge like shape that had fastened onto the two neighbor buildings,its firmly held to them. Its like people can walk under the building and look up. The bridge is made of hard material and then there is a layer of mirror like square sheets moving around it and twisting over it and in the end hit the walls at the sides and spread all over it and disappear gradually. The building is almost two stories, well there is the main floor and there is a little place (which is my office) on the top connected to the ground floor by stairs.
