What LENGKEEK architecten en ingenieurs does

LENGKEEK architecten en ingenieurs b.v. is a privately held Dutch architecture and engineering firm headquartered in De Bilt, Netherlands, founded in 1962. The firm specializes in healthcare architecture (zorgvastgoed), residential housing, and the renovation and repurposing ("renovatie en herbestemming") of obsolete buildings for new care and housing uses. Its portfolio spans woonzorggebouwen (residential care buildings), verpleeghuizen (nursing homes), kleinschalige woonvormen (small-scale living facilities), GGZ facilities, primary-care-plus-housing developments, and general apartment and villa projects, with executed building sizes ranging from 24-unit day-care locations to a 350+ apartment urban district.

The firm's core technology stack is Building Information Modeling using Archicad, with in-house BIM Modelleurs and architects working to the firm's documented Care Concept methodology, an interactive stakeholder-engagement framework for designing buildings for vulnerable user groups (elderly with dementia, people with physical disabilities or acquired brain injury, and mental-health patients). It operates as a multidisciplinary architecture and engineering practice covering concept design, final design, and construction supervision, and has built a circular-transformation capability converting former offices, police stations, banks, and shopping centers into modern care and residential facilities.

LENGKEEK earns revenue through project-based professional services commissions won via direct engagement and competitive tenders from Dutch healthcare organizations, housing associations, and real-estate developers. Its customer base is concentrated in the Netherlands, with named clients spanning care providers (WZU Veluwe, Saamborgh, Aafje, Argos Zorggroep, Pro Persona, Siza, Accolade Zorg, Siloah, Zorggroep Noordwest-Veluwe, Lelie zorggroep, Carebeek, KleinGeluk, Vechtdom, De Zorgmensen) and developers/investors (Explorius, Bouwinvest, RE:BORN Real Estate, Estea, Bouwlinie, Nijhuis Bouw), with several relationships spanning multiple multi-year programs. Marketing is conducted primarily through the company website, an active news/blog section, and LinkedIn; the firm is GDPR-compliant and has no public listing, no external investors, and no disclosed parent company.
