What 2001 does

2001 tbsi is a Luxembourg-based architecture firm founded in 2010 by Philippe Nathan, currently operating from Esch-sur-Alzette with seven collaborators and operating under a two-partner leadership structure (Nathan as founder and Sergio Carvalho as partner since 2017). The firm delivers professional architectural design services across residential, commercial, cultural, and public-sector projects, organized into four categories on its website: Territories (urban planning and masterplanning), Buildings (housing, civic and sports facilities), Spaces (interior design, refurbishment, scenography, installations), and Ideas (research, editorial, lectures, exhibitions, and speculative competition entries). The portfolio spans roughly two dozen named built and unbuilt projects, with notable works including PARK HOUSING, STELLAR, BELVAL PSSSH, JOYPARK, OMNI, LUCA, and FUNDAMENTal, and competition entries spanning Italy, Japan, Belgium, France, the USA, Saudi Arabia, and Switzerland alongside the Luxembourg base.

Revenue is generated entirely through project-based professional services: design fees, project management, and consultation for commissioned or competition-driven projects. Pricing is negotiated per project based on scope and complexity, with no publicly disclosed fee structure. Distribution is direct-to-client via private commissions, invited public-sector architectural competitions (targeting municipal and institutional buyers), and community referrals within the Luxembourg architecture and cultural sphere. The client base is a hybrid mix: private developers and corporations (ce-tec, immo-gestion Frank), municipal governments across Luxembourg and Italy (Ville de Rumelange, Commune di Milano, Communal administration of Bertrange, Établissement public d'aménagement Alzette-Belval), cultural institutions (CASINO Luxembourg Contemporary Art Centre), and academic partners (Free University of Brussels, Tohoku University). Marketing and brand-building rely on the firm's comprehensive project portfolio website (2001.lu), earned media in regional architecture and culture publications, competition participation including the Venice Biennale, and educational outreach (ETH Zurich lectures, MUDAM workshops).

The firm has no disclosed investors, no parent company, no subsidiaries, no app or API products, and no patents or trademarks. Strategic alliances with engineering firm ARUP London, landscape firm BBZ, and Belgian practices CENTRAL and FELT allow the small team to bid on multi-disciplinary and cross-border commissions. Recognition includes the 2015 Luxembourg Architecture Award for the Kitchen Stories project and a subsequent shortlisting, providing reputational moat within the Luxembourg architecture market.

Scale indicators2 records

Recent moves6 records

Expansion highlights4 records

Broad incumbents

• Snøhetta: Norwegian-origin international architecture and design firm with strong public-sector and cultural-institution portfolio; comparable positioning on museum, public space, and territorial projects though at significantly greater scale.
• MVRDV: Dutch architecture practice competing in the same urban regeneration, mixed-use housing, and cultural building categories where 2001 operates, but at broader scale and with full multi-disciplinary teams.
• OMA: Established international architecture firm with deep European public-sector portfolio and competitions track record; a benchmark for the larger practice scale 2001 could potentially evolve toward while remaining architecturally rigorous.
• Studio Gang: Design-led architecture practice combining cultural, civic, and ecological commissions; relevant peer given 2001's emphasis on material innovation, public engagement, and civic-scale cultural projects.
• BIG (Bjarke Ingels Group): Larger international design-led practice competing for the same kind of public cultural, sports, and masterplanning commissions that 2001 targets, though at vastly greater scale and with global delivery capacity.

Direct peers

• Christian Kerez: Swiss architect with a similarly small Zurich-based practice focused on minimal-material, conceptually rigorous architecture and teaching at ETH Zurich, paralleling 2001's boutique scale, design philosophy, and academic affiliation.
• Lacaton & Vassal: French architecture practice celebrated for adaptive reuse and economical material strategies, sharing 2001's emphasis on existing structures, material honesty, and generous low-cost spatial interventions; Pritzker Prize laureate.
• OFFICE Kersten Geers David Van Severen: Belgian architecture practice of comparable scale known for minimal-material, conceptually rigorous design language. Closely matches 2001's boutique size, intellectual positioning, and focus on public and cultural commissions.
• Sou Fujimoto: Japanese architect with small practice origins that scaled to international projects; relevant peer given 2001's work on the Ishinomaki post-tsunami vision and participation in World Expo design competitions.
• 51N4E: Brussels-based architecture and urbanism practice founded by Johan Anrys; similarly sized European boutique firm with comparable design-led philosophy, public-sector urban regeneration work, and competition-driven portfolio across Belgium and internationally.
