Quinzii Terna Architecture is an architecture office based in Milano (Italy), founded in 2012 and led by Chiara Quinzii and Diego Terna, after long collaborations with international practices in Italy (Stefano Boeri and Italo Rota) and in the Netherlands (MVRDV).

It practices architecture, urbanism, landscape design and research in national and international contexts, working in a wide range of projects, supported by publishing, criticism and didactics.

Its activity develops through commissions, competitions, publications and workshops, dealing with projects at different scales, such as urban masterplans and urban visions, architecture, furnitures and temporary exhibitions, also in peculiar historical contexts.

Winner of a research grant from Triennale Milano and Municipality of Milan, QTA has analyzed in depth the Public Spaces of Milan, as part of the 100 Public Spaces for Milan project – published in the book Milan Public Space. An in-progress atlas of everyone’s space, by LetteraVentidue Edizioni in 2021 – and the consequences of the pandemic on the policies and behavior of people in public spaces in Milan, with the research Milan Unlocked. Public Space after Pandemic (that will be published in 2024 for LetteraVentidue Edizioni).
Researches have also been developed internationally through European funds (Creative Industries Fund NL, Dutch Embassy in Rome) and academic collaborations in the Netherlands, China and Honduras for the cities of Rotterdam, Shanghai, Tegucigalpa and San Pedro Sula.

QTA contributed in the improvement of the urban strategies for the Fiume Verde project (The Green River), as part of  Stefano Boeri team, together with ARUP, Mobility In Chain and Studio Laura Gatti, and it developed urban visions and masterplans in different countries, within international competitions, such as in Finland, Bulgaria, Russia, Italy, where their projects have been awarded.

Starting from an in-depth research, published in the book by LetteraVentidue Edizioni Ritorno all’abitare. Una cooperativa in città (Back to Housing. A cooperative in the city), the firm has built an important experience in the cooperative world, developing projects in residential areas.

QTA developed projects dealing with cultural heritage, designing the new Hub Leonardo in the Stelline Palace and Piazza Santa Maria delle Grazie, during the 2015 Milan Expo, and a new professional school in the public farmhouse San Bernardo, in Milan, with Fondazione Società Umanitaria and Comune di Milano.
