During his architecture studies in Paris, among others with Jean-Louis Cohen and Antoine Picon, Hertweck dealt with the so-called Berlin architecture dispute. After successfully completing a diploma awarded by the Académie d'Architecture in 2001, the debate continued, initially within the master’s degree in Modern and Contemporary Architectural History at the Sorbonne and from 2004 to 2007 as part of a dissertation. The work was published in 2010 by the Berliner Gebr. Mann Verlag. In the historicization of one of the great German debates after political unity, Hertweck showed the extent to which questions of architecture and urban development were intertwined with the political and cultural orientation of the young Berlin republic, and warned against a strengthening of a German national movement and its offshoot on the level of architecture and town planning.
After the Berlin architectural dispute, he worked with the French landscape theorist Sébastien Marot on a critically commented new edition of Oswald Mathias Ungers ' 1977 manifesto Die Stadt in der Stadt .  The trilingual publication, published by Lars Müller Publishers in 2013, contains for the first time a significant contribution by Rem Koolhaas with the title "Berlin: a Green Archipelago", which is why the term archipelago theory has become established in the architectural discourse since then.
The examination of the manifesto by Rem Koolhaas and Oswald Mathias Ungers brought Hertweck with the Berlin architect Arno Brandlhubertogether, who also dealt with the archipelago theory. From 2014 onwards, they developed their Dialogic City approach with students from the Academy of Fine Arts in Nuremberg. Based on the definition of the term by the French philosopher Edgar Morin and Ungers' Dialectical City, Hertweck and Brandlhuber showed how antagonistic fields of spatial production such as town and country, community and individuality, or participation and governance, can be brought into a productive dialogue, without one of the fields merging into a synthesis. The work was published in 2015 together with the Munich graphic designer Thomas Mayfried in 2015 under the title The Dialogic City. Berlin becomes Berlin published by Verlag Walther König and was the focus of the exhibition of the same name in the Berlinische Galerie.
Hertweck has been working as a freelance architect since 2005, from 2010 to 2016 in partnership with the French architect Pierre-Alexandre Devernois. A main focus of his work is the relationship between architecture and topography. So he designed and realized a number of buildings that are inscribed below the surface of the earth. Since 2016 he has been working as a freelance architect in Luxembourg, where he is entrusted with the cemetery planning for a municipality in the north of Luxembourg.
In Hertweck's work, dealing with the soil became more and more of a social significance. The question of soil was raised in Dialogic City. In the Luxembourg pavilion curated with Andrea Rumpf at the 12th Venice Architecture Biennale, the excessive privatization of urban land for sustainable urban development was problematized.  In the accompanying edition of the architecture magazine Arch + , Hertweck wrote an atlas of architectural projects that deal with the common meaning of land. Many German media outlets such as the Frankfurter Allgemeine Zeitung, the Süddeutsche Zeitung, the TAZ and the ZDF broadcast Aspects reported on Hertweck and Rumpf's work in Venice. For Niklas Maak from the FAZ it was the most political pavilion at the Biennale. 
From 2009 to 2016 Hertweck was Professor of Architectural Design and Urban Development at the Ecole Nationale Supérieure d'Architecture de Versailles, where he researched urban development in Berlin, Paris, Shanghai, Casablanca, Istanbul and the greater region. In the ARTE neighborhood stories Paris / Berlin from 2015, Hertweck acted as scientific advisor for Berlin and interview partner.  Since 2016 he has been a full professor at the University of Luxembourg, where he heads the master's degree in Architecture, European Urbanization, Globalization . He is currently coordinating a consortium of researchers and planners with Milica Topalovic from ETH Zurich that is working on the prospective planning for Greater Geneva in 2050.
