Today, I want to mention about a construction trip and my observations. Two weeks ago, our professor Onur Yüncü who is the lecturer of Arch 241 course took us to a construction yard. This construction is located in Anatolian Organized Industrial Zone in Ankara. It consists of complex buildings. We observed it’s administrative building. It’s architects are Onur Yüncü and Ayşen Savaş. They are really successful architects and they have worked for METU for many years. They have many awarded projects. Onur Yüncü is working for TEDU now. He is one of our professors in college. This project was designed in a year and it has built for one and half years. Let’s talk about this building.
This building was designed for management, actually it’s kind of a main building of that zone. It’s a really observable structure to understand constructional system of a building because the structural processes and other stuff are transparent and obvious. This building is located in a very natural area. It has gren environment. Also there is small lake. That’s why, the users wanted architects to design a nature compatible structure rather than the other high and common official buildings. Actually, the users wanted a single-floor building which looks like a ranch house. But, architects realised that they need one more floor up in a part. This building consists of three parts. Actually they have just one single floor except one part. It has three floor. One of them is underground floor. Also, it has one more floor up because there is an administration part and there are some chairmans’ offices . That’s why they need to be in higher part of that building. In the first floor, there are many offices, convention halls and some meeting and entrance parts. These parts create a U shape. Then, there is a courtyard between them. The another part next to the others has dining hall, kitchen and also there are some important rooms which have the systems of electricity, heating, water and other stuff. Here, there are some images of this project.

When we talk about the appearance of the whole building, it looks modern and more natural. It hasn’t many glass surfaces. It has some wooden elements, so it creates a natural and warm view. It looks like a house. The whole building is sitting on the stone floor. On that, there are reinforced concrete columns and then wooden roof. The whole structure is displayed as visual. Processes aren’t hidden. Besides,the huge horizontal facades were balanced by using some vertical wooden surfaces. These stone and wooden elements are harmonizing with the environment. There are many basic rectangular elements which consist of glass, wooden and other surfaces. So, there is always a continuity on the facade.
Inside of the building, we could observe the structural system easily. This building has two different structural system. One of them is scissoring in the main part and the other one is classical post structure, also it has just a concrete ceiling. From the protocol to ther other part, this system is changing. And this transition is visible, one is beamed flooring (with wooden) and the other one has no beam. Concrete combines with the scissoring. It also show the transiton between single floor and two-floor structure (except underground floor) There are also hinges between two different parts which are sitting on the different places (topographical). The hinges which are between two different parts are called dilatation like separating (called ‘dilatasyon’ in Turkish) It consists of foam. The wooden beams carry the roof and also there are some another beams which support the main beams (bearer). They are called ‘aşık’ in Turkish. They generally passes frequently and they are not strong and thick like the main beams. On the wooden ceiling there are some kind of heat insulation and roof tile. Besides, the carrying system built and designed that building, and some walls end somewhere according to the this system. So, all spaces were controlled and designed with this system. Moreover, this structural system repeats and then it creates a rhythm inside. By the way, inside of the building wooden element also was used for some coatings and benches. Some electricity cable and kind of these stuff were hided with the wooden covering. And some walls were built with red bricks. So all of them create a warm space inside too.
Dilatation, separation between two different part
The thickness of the columns are generally 35 cm. And they located in horizontal direction with some gaps 5 or 7 metres. And this process repeats after every 4 metres in other direction. When the height of the building increases, the thicknesses of the columns also increase. Also, the lowest one is 2.5 metres and the highest one is 3.5 metres. These tall columns are near to the entrances from parking area and courtyard. They, create the monumental appearance in the entrance.
Besides, when every surfaces end, there is always a gap (hinge) between the other surfaces. For example,when a column end in the roof there is a gap between them. It is the same with the ground. Also, hinges show the differentation of materials and surfaces.
Glass surfaces in this building make the spaces wide and sunlit. It can easily use the day light. Also, people can experience the natural environment when they are in this building. In the corridor between the dinning room and other parts there are some windows which were located in different elevations on the wall. So, all of them create different experiences. Besides, dining room was located in a very far from the protocol part because of the food smell and also, it was surrounded with glass surfaces. So, this situation doesn’t make this space closed and it looks light-well. By the way, in some rooms there are some inside windows. They provides privacy and create a connection between the other spaces in the building. For instance, during a meeting people can close this window with sliding wooden surfaces or they can observe the other when it is open. The offices in the second floor have also huge glass surfaces. These rooms have small resting rooms and bathrooms. In front of these offices there is terrace which looks to the small lake. So it creates a very well view. By the way, in front of the assembly room there is huge space. So, they provides a resting and waiting opportunity.
Besides, there is an also extension from the first floor of the protocol parts. It’s direction is also to the lake. There is a connection between this balcony and outside with staircases.
The courtyard between the U shape will be a warm space with wooden. The iron elements will be covered with wooden and then water can flow between the wooden element then it will flow from the concrete floor to the land. By the way, in the entrance of the protocol part there is a well designed and modern staircases. It’s a really dynamic element, and this part is trying to a make a sense for the entrance. This is really important.
By the way, the main entrance with a hall opens to the parking area. So, people can easily pass to it. When we look at the whole building, it is obvious that it remains it’s naturalness and coherence with the environment.
