TN Plus

What TN Plus does

TN+ is a French landscape architecture and urban planning firm founded in 2002 by Jean-Christophe NANI and Bruno Tanant, headquartered at 30 boulevard Richard Lenoir in Paris's 11th arrondissement. The firm designs public spaces, urban districts, and strategic territorial plans, with a distinctive methodology it terms 'Project Ecology' (placing living systems at the center of design) and a proprietary urban-planning concept called 'Biocité' that organizes cities on an ecosystemic basis using exclusion, superposition, and integration zones. Its service portfolio spans large-scale strategic studies, urban planning, public space execution (streets, squares, parks, multimodal transit hubs), transitional urbanism, participatory co-construction, and a niche specialization in zoological park design (including projects in Vincennes, Helsinki, Saint-Petersburg, and Montpellier).

The firm serves almost exclusively public sector clients — French municipalities, metropolitan authorities, and public institutions — generating professional service fees through open competitions, consultations, and direct public procurement. Notable clients include the cities of Nevers, Troyes, and Roanne, Grand Lyon Métropole, EPAMARNE, the Chambre des Métiers et de l'Artisanat de Lille, and the Société du Grand Paris. Projects are typically delivered as part of multidisciplinary consortia with architects, urbanists, and engineering firms (TVK, Devillers et Associés, 51N4E, Lafayette Architectes, HDZ, SATHY). Operations have also extended internationally to Finland, Russia, Saudi Arabia, and Nepal.

The firm operates a boutique model with approximately 15 current collaborators and a historical alumni network of 40 landscape architects and architects, working on roughly 30 concurrent projects at any given time. It is founder-led, private, and has no external investment or parent company. Since co-founder Bruno Tanant's departure in 2018, Jean-Christophe NANI has led the firm, which has restructured into two poles (Maîtrise d'Œuvre and Études Urbaines) and progressively recruited senior project managers. The firm relies on its portfolio website, biennale participation, and selective social media presence for visibility rather than a software/SaaS go-to-market.
