The fonds consists of photographic materials, architectural drawings, including conceptual, design development, presentation, and working drawings, as well as textual documentation, models, and born digital materials. Also inlcuded are materials regarding publications and exhibitions featuring the firms work. Materials in this fonds document the activities of the architectual firm Ábalos&Herreros over the course of its existence from 1985 to 2008.

The firm also worked on projects outside of Spain including projects for Portugal, Germany, the United States, and Brazil.

The projects of the firm were diverse and covered several sectors of activity, such as mixed-use buildings, waste management facilities, residential buildings, government buildings, sports facilities, educational institutions, urban planning, institutional buildings, commercial buidlings, parks, transportation, etc. Series AP164.S1 documents the firms architectural projects, including exhibitions of their work, from 1986 to 2006.

Series AP164.S3 includes materials related to the promotional activities of the office and materials related to competitions, press reviews and general correspondence of the office. This series also contains materials related to their participation in juries and awards. Ábalos and Herreros' teaching and research activities are documented in the photographic materials of series AP164.S4, which includes slides used by the architects for their lectures and conferences.

Administrative history

In 1984, the architects Iñaki Ábalos and Juan Herreros established the firm Ábalos&Herreros in Madrid, Spain. Renata Sentkiewicz became a partner of the firm in 2001. In 2008, the dissolution of the partnership Ábalos & Herreros led to the emergence of two new firms Ábalos+Sentkiewicz arquitectos and Herreros Arquitectos, both founded in 2006. Herreros also founded the Liga Multimedia Internacional in 1999 and “re-founded” Herreros Arquitectos in 2014.

The architects based their practice “[…] on a professional, academic and research profile” (1). Throughout the existence of Ábalos&Herreros, the firm developed over 160 projects in the fields of architecture and urban design. Significant projects built by the firm include: the Viviendas, locales y garajes en la M-30; Edificio administrativo por el Ministerio del Interior; Ayuntamiento y casa de la cultura de Cobeña; Casa y Studio Gordillo; Biblioteca Usera; Planta de reciclaje de residuos urbanos de Valdemingómez; Aula medioambiental y oficinas, Arico, Tenerife; Pabellón de gimnasia en el parque del Retiro; Barcelona Forum 2004; Plaza y torre Woermann, Las Palmas; Torres mixtas bioclimáticas en el Humedal de Salburúa, Vitoria, etc.

Ábalos&Herreros entered their work in numerous international exhibitions and expositions, and received multiple awards and honours. Individually, Herreros and Ábalos participated in international seminars, and held lectures, conferences and workshops. They were also members of jury panels for international competitions, awards, biennales, and expert committees. Ábalos also took part in the Scientific Committee of the Study Center of the Canadian Centre for Architecture (CCA) from 2005 to 2001 and was the curator of the CCA exhibit Sustainable? in 2007. Both architects have received several awards for their work and have also exhibited their work around the world.

The teaching and research activities of Herreros and Ábalos have been a significant part of both the architects’ careers. Juan Herreros is a full professor at the Graduate School of Architecture, Planning, and Preservation (GSAPP) of Columbia University, New York, and was a visiting professor at the Princeton University School of Architecture, New Jersey, from 2004-2007. In 2006, Herreros had teaching responsibilities as the Morgenstern Visiting Chair in Architecture at the Illinois Institute of Technology (IIT) in Chicago. Previously, he was a “Diploma Unit Master” at the Architectural Association School of Architecture in London from 1998-2000 and was an invited professor at the École polytechnique fédérale de Lausanne (EPF) from 1999-2000. Both Herreros and Ábalos were professors at the Escuela Técnica Superior de Arquitectura de Madrid (ETSAM) from 1984-1988.

Similarly to Herreros, Ábalos has taught throughout his career. Since 2013, Ábalos is chair and professor in residence at the Department of Architecture, Graduate School of Design (GSD), Harvard University, and began teaching at the GSD as early as 2009. He was a professor at the Barcelona Institute of Architecture (BIArch), from 2010-2012, and a visiting professor at Cornell University (2007-2008) and the Princeton University School of Architecture (2004-2007). Previously, Ábalos was chaired professor at ETSAM (2002) and in 1998 he taught as a “Diploma Unit Master” at the Architectural Association School of Architecture and was an invited professor at the École polytechnique fédérale de Lausanne (EPF). In 1995, Ábalos was a visiting professor at the Graduate School of Architecture, Planning, and Preservation (GSAPP) of Columbia University, New York.

Ábalos and Herreros jointly published: "Natural artificial” (1999); "Técnica y arquitectura en la ciudad contemporánea, 1950-1990" (1992); and "Le Corbusier, rascacielos" (1987).

Herreros and Ábalos also published work separately. Some of the titles published by Ábalos include: "La Buena Vida" (2000); "Campos de Batalla" (2005); "Atlas of the Picturesque" (vol. I 2005, vol. II 2007); "Naturaleza y Artificio" (2010); and "Alejandro de la Sota" (2010).

Some of the titles Herreros published or collaborated on include: "Dialogue architecture" (2013); "Housing and domestic space in the XXI century" (2008); "Isla ciudad and Cambio + energía + información : palacios de la diversión, Isla de San Miguel" (2004); and "Potteries Thinkbelt (PTb), 1964-66 : caducidad, educación y energía,” (2000).
