What JSB Construction does

JSB Construction AB is a privately held Swedish general contractor founded in 1997 by Pether Fredholm and headquartered in Asarum, Blekinge. The company builds residential, community, commercial and light-industrial properties nationwide through ten regional offices (Asarum, Stockholm, Malmö, Kristianstad, Jönköping, Växjö, Ronneby, Karlskrona, Hudiksvall, Uppsala) and approximately 380 employees, reporting annual turnover of roughly 2.5 billion SEK. JSB operates two principal construction-contracting formats — totalentreprenad (design-and-build) and utförandeentreprenad (execution-only) — and complements these with standardized industrialized concept houses, notably the Bo Punkt and Bo Lamell Kombohus, the Trygga Boendet, Bo Mini and Care & Comfort lines, and the Förskolan Tallen concept preschool. Two multi-year framework agreements anchor recurring demand: a six-year Sveriges Allmännyttta ramavtal (since June 2020) for public housing and a SKR ramavtal (since 2019) for preschools.

The company's underlying technology is an industrialized, modular construction platform built around standardized concept-house designs (2–8 stories for Bo Punkt, 2–6 for Bo Lamell) using wood and concrete with configurable apartment mixes, complemented by two proprietary digital tools — the Bobyggaren online configurator for cost/area/3D planning and the JSBcraft augmented-reality app for full-scale site visualization. Architecture is delivered in partnership with Wingårdhs Arkitektkontor, and design and development are supported by the SBU Framtid joint venture (with Wingårdhs and Kai-Larsen Affärsutveckling) and the in-house architecture subsidiary Minjar AB. Certifications include ISO 9001, ISO 14001 and ISO 45001 issued by RISE, and projects carry Miljöbyggnad Silver environmental certification.

JSB's go-to-market is direct enterprise sales to Swedish municipalities and public housing companies through competitive bidding, partnering contracts and the Sveriges Allmännyttta/SKR frame agreements; customers include Stockholms stad, Malmö Stadsfastigheter, Nordanstigs kommun, Karlshamns kommun, Vaxholms stad, Karlskronahem, Bostadsstiftelsen Signalisten, Habo Bostäder, Tjörns Bostads AB, Köping Bostad AB and Glada Hudikhem AB. Revenue is generated primarily through fixed-price construction contracts recognized over project duration, with complementary income from in-house property development via JSB Fastighetsutveckling and the Svensk Bostadsutveckling JV. The company is owned by founder Pether Fredholm, who in April 2025 reassumed the CEO role on an interim basis after the departure of Fredrik Leo.

Emerging players

• JM: Sweden-focused residential developer producing multi-family housing primarily for sale to consumers, with a smaller public-housing offering. Adjacent to JSB's residential production but operating a different end-customer model.
• Bonava: Nordic/Baltic residential developer building multi-family and single-family housing for sale to consumers. Comparable residential-product focus but a for-sale developer model rather than JSB's contractor-plus-rental hybrid.

Direct peers

• Veidekke Sverige: Swedish arm of the Norwegian contractor Veidekke, active in residential and commercial building construction. Overlaps with JSB on municipal and developer-led residential projects in Sweden.
• Peab: One of Sweden's largest general contractors, building residential, public, and commercial properties across Sweden. Closely comparable to JSB in scope, customer base (municipalities and developers), and use of standardized housing concepts.
• Byggpartner: Mid-sized Swedish general contractor executing residential, commercial, and public-sector projects, often in smaller cities. Similar geographic and customer profile to JSB outside Sweden's three metros.
• Wästbygg Gruppen: Swedish construction group specializing in modular and industrialized residential building, including concept housing for public-sector clients. Highly comparable to JSB's standardized Bo Punkt / Bo Lamell model.
• Zengun: Stockholm-based Swedish contractor focused on commercial and residential construction for developers and public clients. Comparable regional Swedish contractor competing for similar project types.
• NCC: Major Swedish construction company with strong residential, public-building, and infrastructure exposure. Competes head-to-head with JSB for municipal tenders and public-housing-company contracts in Sweden.

Others

• Serneke Group: Swedish general contractor and developer active in residential, commercial, and public construction. Historically a comparable peer, though recent restructuring activity makes its current operating profile distinct from JSB's.

Broad incumbents

• Skanska: Global construction and development giant with deep Swedish operations. Overlaps with JSB on residential and public-building construction but at vastly greater scale, geographic reach, and capital base.
