CarlGustav Solutions

What CarlGustav Solutions does

CarlGustav Solutions is an independent supplier of prefabricated structural frames for the construction sector, headquartered in Karlstad, Sweden, with regional offices in Torsby, Gothenburg, Stockholm, and Oslo, Norway. Founded in 2011 by Carl-Johan Sahlström and Gustav Berglund, the company designs, engineers, produces, transports, and assembles structural systems in steel, precast concrete (including hollow-core slabs, walls, and sandwich elements), and timber (CLT and glulam), including hybrid combinations of these materials. The offering spans the full project lifecycle from early-phase structural design and 3D modeling through production, logistics, and on-site assembly, with carbon footprint assessments using EPDs and the GHG Protocol as a differentiating service layer.

The business operates a project-based B2B model, generating revenue primarily through fixed-price contracts with general contractors, real estate developers, and municipalities on a project-by-project basis. Customers include Tier-1 Scandinavian contractors and developers such as Skanska, NCC, Consto, Klövern, Castellum, and ByggDialog, spanning residential, commercial, healthcare, education, sports, parking, and industrial end-uses. The company employs approximately 93 people across its five offices and is privately held by parent company CarlGustav Holding AB, with no external venture or private equity investment disclosed.

Commercially, the company pursues a direct sales motion with early engagement in project design to optimize for cost, time, quality, and carbon emissions. It holds ISO 9001, 14001, and 45001 certifications, and is targeting climate neutrality by 2045 in line with Swedish industry goals. Emissions intensity has decreased from 69 tons CO2e/MSEK in 2020 to 9.6 tons CO2e/MSEK in 2024, driven by an increased share of wood and hybrid structure projects. Notable certified projects include the first NollCO2 Renovation v2.0 building in Sweden (Marievik, with Skanska) and a Miljöbyggnad Gold office building (Infinity Stockholm, with Castellum).

Expansion highlights5 records

Broad incumbents

• NCC: One of the largest Nordic construction groups with significant in-house prefab capabilities and an existing customer relationship with CarlGustav; competes for hybrid/timber prefab projects at scale.
• Stora Enso (Wood Products / Building Solutions): Major Nordic forest products company with a CLT and engineered wood building solutions division that competes directly with CarlGustav's timber and hybrid prefab offering, while also serving far broader markets.
• Skanska: Global construction group headquartered in Sweden with substantial prefab and timber initiatives; a key CarlGustav customer but also a potential integrator of prefab in-house.
• Veidekke: Major Norwegian construction and property developer with prefab/industrial building operations, both a potential customer and a competitor in the Scandinavian prefab structural frame market.
• AF Gruppen: Norwegian construction and property group active in civil, building and industrial segments, capable of competing with CarlGustav on large prefab structural frame projects in Norway.

Direct peers

• Contiga: Nordic producer of precast concrete elements (columns, beams, hollow-core slabs), directly competing with CarlGustav's concrete prefab product line for residential and commercial projects.
• Moelven: Norwegian/Swedish group producing glulam, timber and modular building systems; overlaps with CarlGustav's Norwegian operations and timber prefab product line.
• Binderholz: Austrian manufacturer of CLT, glulam and solid timber construction elements, a direct competitor to CarlGustav's timber-based prefab business and a benchmark for industrialized timber building components in Europe.
• Lindbäcks Bygg: Swedish industrial prefab timber home manufacturer using a factory-based modular approach, competing for the same residential and multi-story timber-hybrid projects CarlGustav targets.
• Spenncon: Norwegian precast concrete manufacturer supplying beams, columns, hollow-core slabs and structural elements — overlapping with CarlGustav's concrete prefab business in Norway.
