What K+ Adviesgroep does

K+ Adviesgroep B.V. is a privately held Dutch engineering consultancy (ingenieursbureau) founded in 1999 and headquartered in Buchten (Sittard-Geleen), operating nationwide across the Netherlands. The firm combines installation technology (mechanical and electrical) advice with building physics, acoustics, energy management, sustainable construction, and fire safety advisory services under an integrated methodology branded 'Integrale Advisering' with the motto 'Meer bouwen met minder techniek' (More building with less technology). The portfolio spans eight core service lines: Installatietechnisch Advies, Bouwfysica Advies, Energiebeheer Advies, Duurzaam Bouwen Advies, Akoestiek Advies, Brandveiligheid Advies, Metingen (specialized measurements such as blowerdoor tests, thermography, and acoustic measurements), and the in-house K+ Inspectiedienst for quality verification and validation. A separate sub-brand, Kare+Kure, provides critical troubleshooting, maintenance evaluation, and independent review of existing building installations.

The firm serves project developers, municipalities, healthcare and education institutions, architects, and contractors across seven project verticals: education, healthcare, residential, commercial/utility, multi-functional accommodations, building transformations, and spatial planning. Named engagements span monument-school renovations for Stichting KomLeren, mental-health facility upgrades for Mondriaan and Stichting Pergamijn, advisory work for Maastricht University, a new residential care center at Missiehuis Cadier en Keer with Geelen Vastgoed & Bouw, a swimming complex and community center for Gemeente Landgraaf, an office transformation for Camelot in Arnhem, and a BREEAM-targeted office renovation for GGD Zuid Limburg.

Revenue is generated through project-based professional services with quote-based/project-specific pricing; no fees, rate cards, or transaction pricing is publicly disclosed. The go-to-market is sales-led and direct, anchored on personal contact via the Buchten headquarters (T: 0475-470 470), supported by a project showcase on the corporate website, a LinkedIn presence, and an email newsletter ('ECHT-nieuws'). The firm is independently owned with no institutional investors or parent company identified, and operates with a multidisciplinary team of approximately 25 employees; in Q2 2025 it relocated into a new purpose-built office designed to showcase its integrated installation, building physics, and acoustic capabilities.
