Bio
Frederico Oliveira Vaz lives and works in Lisbon.
After completing a Master’s degree in Architecture at the Faculty of Architecture – University of Lisbon (FAUL) and at the Facoltà di Architettura – Politecnico di Torino (Polito) in 2017, he start working at the studio Aires Mateus.
In 2020, he founded +3a.arch. His work is driven by a search for knowledge and ways of engaging with architecture, realised through more than 115 collaborations including Gonçalo Byrne, Ooda, Masslab, Studio Gameiro and Anne Holtrop.
Within this context, he has developed initiatives such as “hic sunt architectus” – a series of interviews with architects he has collaborated with; “introduction to the profession” – a workshop for architecture students bridging the gap between university and professional practice; and the design of products and furniture collections, which in this case has led him to here.
Briefing
Lisbon unfolds through squares, courtyards, gardens and adros, occupied by outdoor furniture, whether fixed or informally placed.
The collection - Lisbon as an Adro - reimagines the design of these exterior pieces: tables, chairs and supports.
The material - Lisbon stone, expressed in limestone - serves as the physical support and foundation of the collection.
Limestone, presented as existing fragmented blocks, variable dimensions, provides support, giving the lightweight metal a grounded presence in the space it occupies.
The geometry - expressed through the pieces in aluminium, draws on classical forms referenced in sacred geometry, with clear and simple proportions.
The aluminium, cut and folded without welding, inspired by the metallic origami “Oritetsu” by Sam Booth, unfolds according to the rules of ergonomics, structure and geometry, starting from a 1500 × 1500 mm sheet — producing a table (750 × 750 mm), a chair (375 × 375 mm) and a support (250 × 250 mm).
The Adro collection thus aims to establish itself as a reflection of Lisbon in a harmonious tension between present and past.
