BILTZ®

What BILTZ® does

BILTZ® is a Dutch construction, renovation and property maintenance company headquartered in Amsterdam. Founded in 1992, the company operates as one of six operating labels within the United Legendz holding group (alongside FIXZED, IJBOUW, MEERBOUW, MOUTON and TBK), which itself joined the OMDUS national partnership in July 2023 alongside Caspar de Haan, De Variabele and financial backer NPM Capital N.V. The combined OMDUS platform aggregates roughly 1,200 employees across 19 locations in the Netherlands.

The company offers an integrated single-vendor service portfolio covering general construction and renovation, facade maintenance (painting, planned maintenance, monumental painting, wood remediation), fire prevention and compartmentation, concrete technology (repair, injection works, floor finishes, gallery-floor upgrades), project furnishing (flooring, curtains, sun shading), thermal insulation, window-frame replacement, and service/mutation maintenance. Underlying technology includes a proprietary "Online Bewonerscommunicatie" resident communication platform that supports Result-Oriented Cooperation (RGS / Resultaatgerichte Samenwerken) contracts, and Urban Mining practices for circular reuse of demolition materials and biomass-based energy generation. Certifications include ISO 9001, ISO 14001, VCA** and VGO Keur.

BILTZ serves B2B enterprise customers including housing associations (primary segment, e.g., Pré Wonen's 5-year maintenance contract covering Haarlem Parkwijk and Schalkwijk), VvE property managers, healthcare institutions, school groups, institutional investors, government agencies (e.g., Gemeente Amsterdam parking garage P10), and design studios. Notable one-off projects include ABN AMRO's Circl circular building and KLM's Hangar 73 renovation at Schiphol. Revenue is generated through quote-based project contracts and multi-year maintenance agreements, with no public pricing or ARR disclosure. In December 2024 BILTZ relocated to the renovated Lighthouse building at Basisweg 32, Amsterdam.
