Expansion highlights2 records

Broad incumbents

• NCC AB: One of Sweden's largest construction and property development companies, operating across building, infrastructure, and residential development. Overlaps with Johnson & Son's renovation and residential new-build activities but as a broad, multi-segment incumbent.
• Veidekke ASA: A Nordic contractor with significant Swedish operations in residential and commercial construction. Comparable in service lines (renovation, new builds) but operates at substantially greater scale across the Nordic region.
• Skanska AB: Sweden's largest construction and real estate developer, active in residential, commercial, and public-sector building. A broad incumbent that competes for the same pool of customers and tradespeople in residential renovation and small-build work.
• Peab AB: Major Nordic construction and civil engineering group with extensive residential renovation and new-build operations in Sweden. Competes with Johnson & Son for residential customers and contractor labor, particularly when larger projects extend into Mälardalen.

Direct peers

• Byggpartner i Dalarna AB: A publicly listed small-to-mid cap Swedish construction contractor focused on residential, commercial, and renovation projects across regional Sweden. Comparable in service mix (renovation, extensions, new builds) and customer base to Johnson & Son, though operating at a larger scale.
• Zengun AB: A Stockholm-based Swedish construction firm delivering new builds and renovations, primarily in residential and commercial segments. Directly comparable in offering scope (renovation/new construction) and customer targeting, with similar reliance on subcontracted specialty trades.

Regional players

• Derome AB: A family-owned Swedish group spanning building materials, prefabricated housing, and construction services. Comparable as a regional Swedish construction provider with deep local presence, though its primary geography is western Sweden rather than Mälardalen.
