L35

What L35 does

L35 (legal name L35 Arquitectos, S.L.P.) is an international architecture studio founded in 1967 in Barcelona, Spain, operating as a partner-owned professional services firm under Spanish S.L.P. corporate form. The firm delivers architectural design, urban planning, and interior design services across eight core typologies: commerce and leisure, sport, transport, hotels, offices, residential, interior design, and mixed-use developments. L35 runs ten offices across nine countries — Barcelona, Madrid, Sotogrande, Paris, Milano, Mexico City, Bogotá, Santiago de Chile, Istanbul, and Abu Dhabi — with several non-Spanish offices operated through local partner entities (ARES Arquitectos in Mexico, G5 Arquitectos in Chile, AS/OS in Turkey, KEN International in Abu Dhabi). The firm has completed 971 projects in 43 countries over its 55+ year history, with a flagship portfolio of event-driven mega-commissions including the Santiago Bernabéu Stadium renovation (with GMP and Ribas & Ribas), the competition-winning Gran Canaria Stadium design for the 2030 FIFA World Cup, the El Campín cultural-sports complex in Bogotá, the Stazione Roma Termini renovation in Rome, and the New Bazaly Stadium in Ostrava.

L35 generates revenue through project-based professional fees for design, planning, and project management services across commercial, residential, sports, hospitality, and mixed-use developments. Its go-to-market is event-driven and tender-led: the firm actively participates in MIPIM (Cannes), SIEC, SIMI (Paris), and the World Football Summit, and wins commissions through competitive international tenders for large-scale public and private architecture projects. The firm is led by six named partners — Luisa Badía, Alejandro Lorca, Néstor Soldate Ruhl, Itziar Huarte, Caterina Memeo, and Sonia Sanz — who are the principal owners and customer-facing principals. Marketing is content-driven, centered on a portfolio website, sustained press coverage in architecture media (Traits Urbains, Arquitectura Viva, AMC), industry awards (CNCC 2018, ASPRIMA-SIMA 2016, Architecture Madrid 2024, MAPIC 2025, PORCELANOSA 2025), and active social channels (LinkedIn, Instagram, Facebook, Pinterest). L35 carries no external funding, has no disclosed AI/ML capabilities, and is not publicly listed.
