Hans Kollhoff (born 18 September 1946 inBad Lobenstein,Thuringia) is a German architect and professor.
He is a representative ofPostmodern andNew Classical Architecture, as well as a protagonist ofNew Urbanism.
Kollhoff spent the first six years of his life on the family farm in Thuringia at the southern tip of the newly establishedDDR. In 1953 the family escaped to West Germany and settled in Northern Baden.[1]

Kollhoff began his architecture studies at theUniversity of Karlsruhe in 1968. As an undergraduate student Kollhoff was indirectly introduced to the teaching ofEgon Eiermann through the courses that Eiermann had written, but no longer taught, and through his work in the Karlsruhe studio of architect Gerhard Assem who had been a collaborator of Eiermann. In 1974 Kollhoff studied at theVienna University of Technology, and worked for one year at the studio ofHans Hollein.[2] He returned to Karlsruhe to complete his diploma thesis in 1975.[3] Then with a scholarship from theDAAD to attendCornell University, Kollhoff studied, alongsideRem Koolhaas, amongst the stimulating atmosphere prompted by the academic rivalry between architectural historianColin Rowe and architect and theoristOswald Mathias Ungers. Kollhoff became an assistant to Ungers in 1977.[4]
Kollhoff opened his own studio in Berlin in 1978, and since 1984 has run the studio in partnership with Helga Timmermann.
Until 1985, he was an assistant at the HdK (Berlin University of the Arts), and until 2012, Kollhoff was Professor of Architecture and Construction at theETH Zürich.[5]He has held several guest-professorships both at home and abroad. His projects as an architect in Germany and Europe span all scales, from the civic to the residential.
Since 2004 Kollhoff leads the "Bauakademie" project, whose goal is to reconstruct theKarl Friedrich Schinkel building, Berlin 1836, which was demolished in 1962.
Hans Kollhoff's architecture is characterised by a classical building-style and the use of solid, traditional materials, such as stone and brick, worked according to traditional methods. During his career, Kollhoff has developed in the direction of a more and more traditional form, often usingclassical motifs. For this reason he is sometimes criticized for creating an outdated "retro-architecture", that loses itself in a nostalgic imitation of traditional formalism. However Kollhoff's work, with its attention to detail also within the interior space, may be read as a continuation of the work of early twentieth century architects, seeAdolf Loos.
In Berlin, he has designed inPotsdamer Platz a high-rise tower in an old-New York brick style, forDaimlerChrysler. He was also responsible for the master planning of high-rise buildings on theAlexanderplatz.[6] Among his works are also the reconstruction of theformer Reichsbank into the new Foreign Office, and the so-calledLeibnizkolonnaden in the district of Charlottenburg-Wilmersdorf near theKurfürstendamm. In 2005 he constructed the inner rooms of the exclusive night clubGoya on Nollendorfplatz, that opened on December 1 in the building where theMetropol had formerly been. InFrankfurt am Main he has erected the 88-meter-tall (289 ft) residential building Main Plaza in theDeutschherrnviertel. AtAlte Messe Leipzig, he designed in 1996 one of the nine head offices of theGerman Central Bank.[7] which was in 1999 awarded theArchitekturpreis der Stadt Leipzig (Architecture Award of the City of Leipzig).[8]
Outside of Germany, Kollhoff has designed numerous buildings in theNetherlands. His first project, thePiraeus, was realized in 1994 on theKNSM Island inAmsterdam.[9] His most known projects in the country however were built inRotterdam: both theStatendam high-rise tower at theBinnenrotte and theCompagnie residential buildings at theKop van Zuid stand out in their respective area's.[10][11][12] Other notable projects of Kollhoff in the Netherlands includeDe Colonel inMaastricht, theFoortse Towers Vathorst inAmersfoort and the building of the DutchMinistry of Justice and Security andMinistry of the Interior and Kingdom Relations (also known as theJuBi-building) at theTurfmarkt inThe Hague – his highest project yet.[13][14][15]
