What bgb does
bgb a.s. is a privately held Danish construction company founded in 1980 by Bertel Gantriis, headquartered in Skive with a project department in Ishøj. The firm operates exclusively for professional B2B customers — property developers, institutional investors (notably pension funds such as ATP, PensionDanmark, Velliv, and KLP Ejendomme), corporate clients (Nordea Ejendomme, Tryg), and public sector (Copenhagen Municipality) — and explicitly does not serve private individuals. It is described as one of Denmark's largest carpentry and joinery firms, employing 150-240 craftsmen plus apprentices, supported by wholly-owned workshop subsidiary Multika Snedkerier.
The company executes projects under four contract structures: totalentreprise (turnkey), hovedentreprise (main contractor), storentreprise (large-scale), and fagentreprise (specialist trade). Core service lines are total/main contractorship for new construction (notably mass timber), total/main contractorship for conversion and renovation (including occupied buildings and heritage-listed properties), and in-house carpentry and joinery services spanning windows, roofing, facades, office fit-out, and residential interiors. The company has developed proprietary construction methods including a T-jern guiding bar for plasterboard skirts that eliminates diagonal bracing, moisture-control strategies for Danish timber-frame construction, and steel tension systems enabling 7.5-meter cantilevered balconies. It has built a differentiated sustainability track record through DGNB certifications, including Denmark's first comprehensive renovation to reach Platinum level (Hellebæk Klædefabrik).
Revenue is generated entirely through one-time project contracts rather than recurring licenses or subscriptions, with pricing not publicly disclosed. Go-to-market is sales-led direct contracting via tendering, reverse tendering, and direct negotiation with professional clients, with marketing conducted primarily through the bgb.dk corporate website. Key customers visible in the project history include Fælledby P/S (209-unit timber district), ATP (Hillerød headquarters extension), Gefion Group (Engvej 653-unit conversion), Nordea Ejendomme (Frederiks Brygge 1,300 units), and KFI Erhvervsdrivende Fond (Toften). Management includes project partners Jeppe Mulvad Jeppesen and Mads Volmer Nielsen and in-house DGNB consultant Jakob Kæstel.
