My name is Emir Hajar. I am from Turkey. I live in Istanbul and I am an architect. My company is a Latif Sharkit Akchan Consulting. I have been working in this company for seven years and also for four years I am a partner of the office. Our project is Dardan al Administration building. It is located in Istanbul in Tarabyan. It was an existing wooden house in Vosferu. It is built in 19th century. The windows are so small and the center parts are completely dark because of these small windows. And if we use it like a floor of office, first we need to find some solutions to create lighter spaces. At the main entrance we have one wind box. The main entrance doors, these historical wooden doors are at daytime, at the working time they are always open. And at the wind box we have two double glass doors. This glass can give us some connections from interior. At the back of the building we have completely new part. We make the top part of the building completely from glass. With this glass roof we try to provide more light spaces inside. In the previous staircase it doesn't work clearly. So we make a compact staircase unit. And again we just make all this staircase part from glass to take also light from this part. Building's white is just 5 meter and also less than 5 meter. And it was like a tunnel. We just want to show the building like it continues the other side. So we use at the top of the dividers most reflective materials like mirrors or glasses. The workers, the people feel they are safe like they are they stay in the bigger building.
