SumProject + SumResearch

What SumProject + SumResearch does

SumProject + SumResearch is a Brussels-based architectural and urban design practice tracing its origins to 1974 and operating through two co-located Belgian legal entities, SumProject Architecture & Engineering BV CVBA and SumResearch SA, jointly trading under the Sum brand from Boulevard de Waterloo 90. The firm provides sustainable architecture, civil engineering, urban design, masterplanning, and strategic urban policy consultancy to both public-sector clients (governmental and public authorities) and private-sector clients (developers, corporations) across Brussels, Flanders, Wallonia, and northern France. Its core methodology is described as interdisciplinary research-driven design that integrates architecture, engineering, and urban studies, with documented experience in heritage restoration projects such as Abdij Roosenberg and Beguinage Bruges.

Commercially, the firm operates as a project-based professional services practice. Work is acquired through direct client engagement and competitive tenders/competitions rather than product sales or subscription pricing, and revenue derives from professional service fees on these engagements. The firm maintains an 11-50 employee headcount range, with no disclosed external investors, parent company, subsidiaries, or M&A activity. Its marketing footprint consists of a corporate website (sum.be) plus LinkedIn, Facebook, Twitter/X, and Instagram profiles, and there is no software product, app, or platform offering - all output is delivered as professional services through human-led design and consultancy engagements.

The business is independently and privately held, with no evidence of external funding, and has remained continuously operating for 50 years as of 2024. The firm shows no AI/ML capability, no proprietary technology patents, no publicly disclosed awards, and no documented partnerships or alliances. Its defensibility rests on brand longevity, local regulatory and heritage expertise, and an interdisciplinary model that pairs design delivery with policy-level urban research under a unified brand.
