Architectuurbureau

What Architectuurbureau does

Architectuurbureau Sluijmer en van Leeuwen BV is a full-service architecture firm headquartered at Kerkstraat 21A in Utrecht, Netherlands, operating as a private Dutch BV since the late 1990s. The firm specializes in four integrated practice areas: restoration, new construction, sustainability (verduurzaming / BENG compliance), and repurposing (herbestemming), spanning both commercial (utiliteitsbouw) and residential (woningbouw) sectors. Its core methodology is a "Total Engineering" approach that integrates architecture, structural engineering, and building installations into a single coordinated design team — applied notably in complex projects such as the BENG-compliant Junior Campus renovation in Hilversum. The firm serves four primary customer segments: educational institutions (a long-standing relationship with Stichting Alberdingk Thijm Scholen covering multiple school projects), heritage property owners (municipalities and foundations managing rijksmonumenten), housing associations and developers, and private clients commissioning custom villas.

The firm's business model is professional services fee-based, with project pricing determined by scope, complexity, and client requirements rather than standardized tiers. Projects are acquired through competitive tenders, direct commissions, and repeat client referrals within the Dutch market. A documented portfolio of 73+ completed projects includes notable works such as Sixth Avenue (Almere), Akoesticum national music/dance/theater training center (Ede), International School Almere, Fort Vreeswijk multipurpose facility (Nieuwegein), and the Unilever Knorr factory repurposing (Nieuw Loosdrecht). Marketing is conducted primarily through a portfolio-driven website, LinkedIn presence, and earned media in industry publications (NRC Weekend, Architectuur.NL, RTL 4). The firm has received multiple industry recognitions including the Architectuurprijs Almere 2018 (Children's Jury), Benelux Trofee Thermisch Verzinken 2009 (second prize), and nominations for the Nationale Staalprijs 2002 and Living Daylight Award 2010. The practice operates with approximately 5 employees and is independently owned with no disclosed external investment or parent company.
