K3 Gruppen Ab

What K3 Gruppen Ab does

K3 Gruppen AB is a Stockholm-based private construction and renovation contractor that bundles multiple trades into a single totalentreprenad (turnkey) delivery model. The company offers flooring (sanding, laying, treatment), painting (interior, facade, windows), carpentry (window renovation, kitchens, terraces, custom built-ins), bathroom renovation (tiling, VVS, electrical, finishing), fixed electrical installations, and a full cleaning-services vertical (home, move-out, office, post-construction, stairwell). It also runs a dedicated Platsbyggnationer line that adapts IKEA METOD cabinet frames into custom wardrobes, bookshelves, and kitchens for the Stockholm market. The core technology is traditional construction craft executed by an in-house multi-disciplinary team (electricians, tilers, painters, carpenters, cleaners) using modern execution methods, with no proprietary software platform disclosed.

The firm serves three customer segments in the Greater Stockholm region: private homeowners (the primary segment), Bostadsrättsföreningar (housing associations) requiring building maintenance, and business/corporate clients needing office cleaning and commercial renovation. Distribution is exclusively direct via the company website (k3gruppen.se), phone (08-777 51 00), and email ([email protected]), with social proof layered through Instagram (@K3gruppenab) and Reco review badges. Go-to-market is sales-led: customers request free quotes, the firm conducts site visits, and projects are booked against written fixed-price offers, with ROT tax-deduction administration handled directly on the invoice for eligible residential work. Revenue is project-based professional services revenue, with publicly disclosed unit pricing in SEK ranging from approximately 250 SEK/m² for basic patio sanding up to 2,600 SEK/m² for chevron parquet laying. It claims to perform thousands of assignments per year in Storstockholm despite operating with a 1-10 employee core team, implying heavy reliance on subcontracted execution capacity.

Direct peers

• Beijer Byggmaterial: Major Swedish building materials retailer with project/installation services. Overlaps with K3 on renovation supply plus execution, and serves the same Swedish homeowner customer base.
• Byggmax: Swedish building materials retailer with installation services across many of the same trades as K3 (painting, flooring, carpentry). Competes for the same Stockholm homeowner renovation spend, with a more retail/chain model.
• Woody Bygghandel: Swedish building materials retailer offering project support and contractor referrals for home renovation trades — directly comparable customer and service overlap with K3 Gruppen.

Broad incumbents

• NCC AB: Large Swedish construction company with residential and commercial building operations. A broad incumbent operating in the same construction/renovation space, but at a much larger scale and scope than K3's local services.
• JM AB: Swedish residential property developer active in Stockholm. Adjacent to K3's market — both serve Stockholm residents seeking home upgrades, though JM focuses on new-build sales vs K3's renovation services.
• Skanska AB: Global Swedish-headquartered construction and project-development company. Operates broadly in residential and commercial building where K3 competes at the local renovation services layer.
• Peab AB: Major Swedish construction firm with residential, civil, and renovation segments. Comparable industry overlap with K3 but at enterprise scale and broader geographic footprint.

Others

• Ahlsell Sverige: Swedish technical wholesale/distributor serving professional contractors and tradespeople. Adjacent ecosystem player — supplies materials that contractors like K3 consume — rather than a direct competitor.
