Arco - Architecture Company

What Arco - Architecture Company does

ARCO – architecture company S.àr.l is a Luxembourg-based architectural practice founded in 1989, headquartered at 3, rue des Trois Glands in the Pfaffenthal district of Luxembourg City. The firm delivers full-service architecture across residential, educational, healthcare, commercial, and heritage renovation sectors, with explicit positioning in sustainable construction, energy-efficient design, and wood-construction methods. Core technical work is executed on Archicad BIM platforms, supporting integrated design, modeling, and project documentation across new build and renovation workflows.

The firm operates as a partnership-structured private limited company generating revenue primarily through project-based professional fees from a dual public/private client base. Public-sector work flows through competitive procurements and PPP tenders (notably the Lycée Technique Bonnevoie win with partners Jim Clemes and Mersch in 2017, and Bourglinster Campus competition participation), while private work covers developers and individual residential clients. Go-to-market therefore combines direct client engagement with architectural competitions — the latter being the dominant route into the firm's larger institutional mandates.

Leadership is organized around six named partners: managing partner Georges Lamesch, managing architect Sylvie Gaspard, and associates Philippe Poncé, Stéphanie Jungmann, Gary Haycock, and João Ferraz. Headcount sits in the 30+ range (firmographic band 11–50), consistent with a mid-sized boutique practice. The firm has accumulated multiple Bauhärepräis industry awards (2012, 2016, 2020, 2024) and a 2015 Green Building Solutions Award at COP21, indicating sustained recognition in the Luxembourg market and reinforcing positioning for sustainability-weighted public tenders.

Broad incumbents
