An apartment begins, in the buyer’s imagination, with a view. A balcony, perhaps. A kitchen with enough room for two people to disagree about dinner. In JM’s business, it begins with a piece of land and a sequence of decisions made before either person arrives. Who owns the site? What may be built? Which details have worked before? How many buyers will commit before construction starts?
- JM connects land, design, construction, sales and aftercare.
- Repeatable methods have shortened production time, the company says.
- Financing and buyer confidence still decide whether homes sell.
The apartment begins with a patch of land
John Mattson founded the company in 1945, when Sweden needed housing. It built for organizations including HSB, while pursuing its own residential developments. That second activity matters. A contractor can finish somebody else’s specification. A developer must decide what should exist, put money behind the decision and find someone willing to pay for it.
Today JM operates in Sweden, Norway and Finland, concentrating on metropolitan areas and growth regions. Its work runs through land acquisition, planning, design, construction and sale. In Sweden, JM@Home also handles technical and financial management. The customer gets a home; the company gets a long chain of responsibilities, with several opportunities to make a good decision expensive by following it with a bad one.
The business earns its development margin by turning land into completed homes and selling them, with management services extending the relationship. Capital goes in before the final customer pays. That makes the timing of permissions, construction and sales part of the product’s economics, even when the brochure concentrates on the kitchen.
Repetition, with a view
The useful phrase here is “structural capital.” It sounds like something stored in a filing cabinet. For JM, it includes proven solutions and methods that can travel from one project to another. Its development process favors repeating what works. Experience gathered after people move in can return through management and warranty work to inform the next building.
In 2024, JM brought its pre-construction capability fully in-house, including designers and installation planning managers. That places expertise closer to the decisions it must later execute. The company’s employee Instagram account offers a less formal view of the organization: a different colleague takes over every two weeks. Behind the repeated methods are people doing distinct jobs, whose knowledge has to survive the handover between them.
There is a human reason to care about that rather dry mechanism. Buyers encounter a building once, at a particular moment in their lives. The developer encounters versions of the same problem repeatedly. Remembering the answer should mean fewer opportunities to discover the mistake in somebody’s bathroom.
Location keeps this from becoming a purely industrial exercise. Ture Gård in Sollentuna, started in September 2026, puts 100 apartments around a green courtyard near shops and commuter rail. It completes a block of 221 homes alongside two earlier projects from JM subsidiaries Borätt and Seniorgården. Repeat the useful method; still pay attention to the railway station.
JM serves households buying new homes, alongside associations needing management and purchasers of housing projects. Alternatives include HSB, OBOS, Peab and Skanska in Sweden, with different competitors elsewhere. Its pitch rests on coordinating the development chain, established building methods and environmental requirements. None of those removes the need for a buyer to like the actual apartment.

A buyer can want a home and still wait
In December 2025, chief executive Mikael Åslund said JM had shortened production time by 30% since 2019. The company’s Productivity Boost initiative aims to reduce production costs by up to SEK 250,000 per home. Those are different statements: one describes a reported improvement; the other describes an ambition.

The pressure was already visible. JM’s 2024 report described lower housing prices meeting higher costs and squeezing margins. The company began a strategic review that autumn. By its 2025 year-end report, it described a smaller Stockholm project-development organization and an agreement to sell contracting operations that had struggled with profitability. Operating experience had made a broader business less appealing.
Its October 2026 update shows the tension persisting. Nine-month operating profit rose to SEK 390 million from SEK 305 million under segment reporting. Yet third-quarter homes sold fell to 462 from 562. Faster production and improved earnings can coexist with reluctant customers. Revenue also differs between segment reporting and IFRS, so choosing the accounting basis matters before declaring a recovery.
Quarterly sales fell even as operating profit improved. Figures use JM’s segment reporting.
Half the ownership, all the living
JM Deläga, introduced in 2023, approaches the buyer’s problem from another direction. For selected Swedish apartments, a customer can initially buy at least half, with JM retaining the rest. The resident uses the whole home and can acquire further shares. It is a practical response to the distance between wanting an apartment and financing all of it.
The price of that bridge is a monthly co-ownership fee on JM’s share, alongside the association charge and ordinary living costs. JM’s illustrative example reduces a SEK 4,000 co-ownership fee at 50% ownership to SEK 2,400 at 70%. These are examples, not a universal tariff. Availability, mortgage approval and the buyer’s future ability to purchase the remainder still matter. Half the ownership does not mean half of every bill.
The concrete underneath the promise
JM began building low-energy homes in 2008 and introduced Nordic Swan requirements for self-developed housing entering design from 2018. In 2025 it partnered with cement company Cemvision and became a minority shareholder. The appeal is specific: concrete carries substantial material emissions, so changing its ingredients can affect the building before its first electricity bill arrives.
Another business can borrow the discipline: preserve proven answers, make environmental requirements part of purchasing, and learn from customers after delivery. The conditions matter. Repetition helps when projects share useful features; it cannot approve a planning application or make a mortgage affordable. JM’s method earns its keep in that space between a repeatable building process and a household making a decision it may make only once.
