Union of Chambers of Turkish Engineers and Architects

The Union of Chambers of Turkish Engineers and Architects (Turkish: Türk Mühendis ve Mimar Odaları Birliği, TMMOB for short) is a confederation of all chambers of architects and engineers in Turkey. The union was founded in 1954 as an umbrella organization of ten chambers with around 8,000 members. As of end 2013, the union represents 24 chambers with a total membership of 445.365. It is headquartered in Kızılay, Ankara.

In July 2013 the Justice and Development Party rushed through a bill removing TMMOB's role in approving urban development proposals, apparently in response to TMMOB's support of the 2013 protests in Turkey.
