Materials

The materials of the space are important in creating the mood of the space. The unique design of the roof will cast shadows onto the floor that will change the feel of the space over the course of the day. The materials of the space will need to reflect that. 

As said before, the roof will be made from Danpalon. The fins of the roof will be made from Carbon Nanotubes, to reduce the structure that will be required to support it, and to keep the with down. 

The floors of the space will be made from polishded concrete and the walls from preset concrete slabs, that are pured offsite. Because of this they will not have the reinforcing marks that are generally associated with concrete. They will also not be solid concrete walls, which will reduce the weight of the structure. The walkways will use the same materials, but reinforced with Carbon Nanotubes, to allow the structure to span the gap of the central space. This offsite pouring of concrete has been successfully used on building, including the Tel Aviv Museum of Art by Preston Scott Cohen. The building can be seen here (http://www.pscohen.com/tel_aviv_museum_of_art.html) and the effect will be similar to this building, which can be seen below. 

The effect that the concrete and light will create will be similar to the work of Tadao Ando. The effect can be seen in the image below, which shows the main atrium in the space, which is surrounded by ramps and retail spaces. 

The shadowing would be softer at certain times of the day, when the sun is not angled directly down as it is in this image (Sun angle is at Brisbane on 31 January and 12:30pm)
