What A43 does

A43 is a privately held architectural firm founded in 2002 and headquartered in Vila Nova De Gaia, in the Oporto metropolitan area of Portugal. The firm operates as a multidisciplinary design practice, offering services across five integrated disciplines: architecture, interior design, product design, urban planning and landscape, and consultancy. Under the leadership of architect Fernando Mendes, A43 serves a diverse client base spanning residential, commercial, hospitality, and industrial segments. Named engagements include DoTe's Restaurant Group (described as the largest restaurant group in Lisbon), a Plastics Factory in Valongo, and the Machamba Resort & Safari in Mozambique, alongside private residential commissions.

The firm's revenue model is project-based, driven by design commissions rather than recurring contracts. Beyond traditional architectural services, A43 has developed a proprietary product design line that includes the Momento lamp, LUA bedside table, and Ego dressing table, opening a secondary revenue channel in consumer goods. The firm maintains an operational footprint across four countries — Portugal, the United Kingdom, Mozambique, and Switzerland — providing both geographic reach and exposure to varied market conditions.

A43 has accumulated industry recognition over two decades of operation, including selection for the Miami Architecture Biennial (2009), the Young Architects award (2010), a Denver Architectural League Honorable Mention (2013), and the Architecture Aluminum Technal Award (2013). The firm maintains an active social media presence across Instagram, Facebook, LinkedIn, and YouTube, and is currently hiring for a Senior Architect position requiring 5-8 years of experience, signaling ongoing investment in senior delivery capacity. With a team of 11-50 employees, A43 operates as a mid-sized design practice rather than a large international firm.
