What oitoo does

Oitoo is a privately-held architecture studio founded in 2017 and headquartered across two Portuguese locations: Porto (Rua António José da Silva) and Lisbon (Avenida da Igreja). The studio operates through a dual structure: the Office, which delivers architectural design, urban planning, and construction across residential, public, cultural, and educational typologies; and the Observatory, a research arm that investigates under-utilised buildings, ground-floor spaces, and forgotten urban territories. Founding partners Laura Lupini, João Machado, Diogo Zenha de Morais, and Nuno Baptista Rodrigues lead the practice, supported by a small team of architects and project staff.

The studio's core practice centres on adaptive reuse, ground-floor reactivation, and urban regeneration, applied across Portugal and select international competitions. Core service lines include architecture and urban planning (new build, refurbishment, and adaptive reuse), research and curation through the Observatory, and editorial output via yellowred magazine and the book 'yellowred, on reused architecture.' Specific methodologies include a ground-floor reactivation approach (exemplified by Reground Porto, armazemcowork, and the ground-floor house projects) and recurring research products such as Becos Com Saída, oitoo's Walks, DESTRINCO, CARPET, and the newer Habitar sobre o habitado programme. Clients include Almada, Lisbon, Porto, and Portimão municipalities, Fundação Santander, Museu de Serralves, OASRS, and unnamed private residential clients.

Oitoo generates revenue through professional service fees tied to architecture commissions, acquired primarily via public-sector architecture competitions (open and invited), direct public commissions from municipalities and institutions, and private residential/commercial commissions through referrals and direct engagement. Distribution runs through the studio portfolio website, Instagram and LinkedIn, academic publications, and active competition participation. Geographic reach is concentrated in Portugal with selective international competition entries (Switzerland). No external funding, investors, or parent entities are disclosed.

Direct peers

• ARX Portugal Arquitectos: Portuguese contemporary practice delivering housing, public buildings, and urban regeneration projects at a scale and typological range closely matching oitoo's portfolio.
• ateliermob: Portuguese architecture collective that pairs design practice with research and community-engagement work — a structural parallel to oitoo's Office + Observatory dual model.
• CVDB Arquitectos: Portuguese practice of similar scale with a comparable portfolio of residential, public, and adaptive-reuse projects; competes with oitoo for the same pool of municipal and private commissions.
• Pedra Líquida: Portuguese architecture firm with strong specialisation in heritage conservation and adaptive reuse, directly competing for the same adaptive-reuse and renovation commissions that drive oitoo's growth.
• Menos é Mais Arquitectos: Contemporary Portuguese architecture practice of comparable size with overlapping focus on public-sector work, residential projects, and urban regeneration; closest direct peer by typology and scale to oitoo.
• Bak Gordon Arquitectos: Lisbon-based contemporary architecture firm working on residential, public, and cultural commissions at a similar scale to oitoo, with comparable typological breadth and design-led positioning.

Broad incumbents

• Souto de Moura Arquitectos: Pritzker Prize-winning Portuguese firm working across residential, public, and adaptive-reuse typologies; significantly larger and more established than oitoo but competes for headline public commissions in the same market.
• Aires Mateus: Internationally recognised Portuguese practice with a comparable typological range (residential, cultural, public) but operating at a much larger scale, often competing with oitoo for major institutional briefs.
• Lacaton & Vassal Architectes: Pritzker-winning French firm whose practice is defined by retention and adaptive reuse of existing buildings — a philosophical and methodological parallel to oitoo's specialisation, though at international scale.

Emerging players

• Caruso St John: European practice known for adaptive reuse of historic and existing buildings with a research-driven approach; shares oitoo's design philosophy around working with existing fabric, though operates at a larger international scale.
