Stone Projects

What Stone Projects does

Stone Projects is a Dutch independent consultancy, founded in 2016 by Matthieu Steenbeek and headquartered in Utrecht, that specialises in office renovation, refurbishment, transformation, and fit-out project management. The firm serves both property owners and investors (for portfolio conversions, multi-tenant repositioning, and technical due diligence) and tenants (for relocations, workplace strategy, and interior build-outs), with named engagements spanning Unit4, EY, Habion, Houthoff, a.s.r. real estate, Journey Offices, Gimeg, Sanoma, and Fromm Nederland, plus a broad logo wall of larger occupiers and institutional investors including CBRE, Linklaters, Baker McKenzie, TomTom, Optiver, and Sagax.

The company's underlying offering is not a software product but an integrated advisory service across eight modules: Project Management, Technical Advisory, Cost Management, Workplace Concepts, Sustainability Services (BREEAM, WELL, EED), Programme Management, Technical Due Diligence, and Construction Monitoring. Its technical backbone is deep expertise in integrating building installations, construction, and sustainability, combined with a proprietary annual purchasing database of approximately €45 million in client project procurement, which feeds benchmark cost data back into budgeting and tender evaluation. The firm operates with dedicated teams of 2–3 colleagues per client and emphasises transparent pricing with no hidden fees or supplier kickbacks.

Commercially, Stone Projects is a sales- and referral-led professional services firm that wins project-by-project engagements, primarily in the Netherlands with international capability through a partnership. Revenue is generated through project-based fees and multi-year contracts; pricing is not publicly disclosed. The firm is privately held, founder/partner-owned with no institutional investment, and has grown from a single founder in 2016 to a partner bench (Sjoerd van den Assem, Sander van de Belt, Jurgen de Vries) supported by a COO and a team of 11–50 staff across project management, cost management, and technical advisory.
