İller Bankası Building (Axonometric, Ortographic Drawing and Diagram)

The Iller Bankası’s building was design by Seyfi Arkan who is a successful and important  Turkish architect in Turkey. When we look at the history of ‘İller Bankası’, we see that this institution has important effect in Turkey. The main client of the building ‘Iller Bankası’ was founded in 1933 and its former name was ‘Belediyeler  Binası’.

When we analyze design qualities of  the building, using materials were attracted to me. Iller Bankası is one of the most interesting constructions in the Turkish architecture in terms of using materials. Seyfi Arkan used new and local materials in extend and intent surfaces of the building. Especially, Arkan used a new style of  Ankara stone which never seen before in extent surface of the building. Structure of three floors covered with stones and was made up by rectangular windows are different materials as well as in terms of usage from structure of ground floor. On the other hand, it is attracted attention that various ingredients like glass, bronze, marble and papier-mache used together in a meticulous craftsmanship in the entrance of the building. The first floor includes offices belonged to the Bank and the other floors designed a simple shape of ‘L’. Also ground floor was designed regressions and emptying with this way provided dynamism in the ground floor. When looking at as a whole, after the street facade of the building was figured so simple, Seyfi Arkan applied sort of circular lines never seen before in Ankara in order to enrich the lower part of the construction5. Arkan applied to it very successfully [1]. Plan of the ground floor has three different parts which placed in the centre  and these parts have hierarchy each other. İller Bankası building, which combines both the simplicity of the expression and richness of design, might be described as a very instructive example of the modernist approach[2]. The basement of the Bank building divided into vaults, cloakroom, workers restrooms, a woodshed, bank archives, apartment store, and a gas shelter. Both ground and the first floor belong to the bank, the second floor to the Directorate of Public Works and also the third floor has been planned for housing[3]. On the other side, the top floors were used order of windows and covering of Ankara stones verticality while horizontal and circular lines dominate in the ground floor and also main entrance was emphasized with used semicircle.

Variation-III (Final model )


In my new model(variation-III), I created a new variation of Variation-II. For the juxtaposed part, I want to tell how I have achieved them. I decided to separate parts which has different characteristic qualities. Therefore, I used planar elements and made up linear and planar parts. Group seen like linear was stretched more, and planar group was made bigger to feel more planar. With this way I divided two parts. Its main purpose is to remark juxtapositional area between them and in the middle of the model I used linear and planar elements together and acquired juxtapositional volume in there. I used a lot of linear andplanar elements together and revealed different juxtapositional volume.  On the other hand, we were given an opportunities to make mass, so I thought to use massive area in the juxtapositional area to remark it more and  I decided to use mass just on the linear elements. In this new model, we were given a new material(transparency) to used on it, but it is not using an element. My professor said that you should use the new material as a language of your model. I decided to use transparency material to divide some volumes. For instance, A planar element divides two different volume in the model and I used transparency instead of the planar element with this way, I acquired three different juxtapositional volume also strong volume.
