DEN Group = Multifunctional Premises + Homes + Services

DEN Group brings together a special group of companies and people with a shared goal. This goal is to serve the customers in a comprehensive way in their unique individual dreams related to living, working, and free time. DEN offers an extensive and constantly improving range of products and services covering the design, building, renting, and life cycle services of homes and spaces.

We utilize our refined and efficient execution process to ensure our customers a high-quality outcome. Our efficient and quality execution is based on a refined delivery process. From planning to our own production facilities in Nivala and Alajärvi, to our own DEN Tekniikka technical building systems services, and the earthworks construction and planning services of PohjanTeko and PohjanGeo, the entire implementation process is in our own hands, complemented by our established partners.

The DEN Group offering consists of multifunctional premises, homes, and services. This offering enables us to meet our customers’ needs in a more comprehensive way, and to ensure, for example, agile deliveries of flexible multifunctional premises as well as an effortless and convenient way of acquiring your own turnkey home. In order to make everything easier for the customer, DEN offers a single contract at a fixed price, covering a complete package including earthworks and the planning and building of single-family homes – every step of the way from earthworks to a completed turnkey home.   

Multifunctional Premises

Multifunctional Premises are represented by Talliosake, a provider of solutions for flexible and multifunctional premises, and the market leader in its branch in Finland. Talliosake has created a unique concept for businesses, consumers, and investors. The premises serve their users as business premises, recreational space, storages, and investment objects. Talliosake is also a registered broker of rental apartments that helps the investor in determining the appropriate level of rent charged and in finding a suitable tenant. The first construction projects in Sweden based on the Talliosake concept were launched in 2018.


Homes are represented by Designtalo, Finnlamelli, and the shared brand of Ainoakoti in cooperation with K-Rauta. DEN Group is the market leader in turnkey single-family homes in Finland. Of these brands, Designtalo is a pioneer and trendsetter in turnkey, tailor-made single-family homes in Finland. The implementation of Designtalo’s construction process has been long refined, with the aim to guarantee a high-quality outcome for all customers. Helping our customers in designing their dream home are our trained home tailors (Kotiräätälit) who know how to make your home-related dreams come true. Designtalo also invests heavily in work safety. Proof of this is, for example, the development and use of our own fall prevention system.

Innovative spirit and courageous entrepreneurship

The strength of the DEN concept is the story of its dynamic brands, characterized throughout the years by the visionary intuition of brave entrepreneurs, market-changing innovative thinking, and open-minded utilization of the latest technology. 



Pohjolan Design-Talo was established in 1989. The company identified the trends in the market and the changing needs of consumers. It rose to the position of a leading developer of the turnkey concept, which helped it achieve market leadership in the fastest-growing segment, single-family homes.

In the Kotiräätälit service concept, the home tailors of Designtalo support the consumer from the very beginning of planning their new home every step of the way to the finishing touches.

Designtalo is a pioneer in improving the energy efficiency of single-family homes. In 2011, the company obtained Passive House Certification for its Housing Fair house. Three years later, in 2014, Designtalo built its first nearly zero-energy home.



Finnlamelli, established in 1995, has its roots in the long tradition and expertise of Finnish sawmill and log house industries. By utilizing this know-how, the company rose to the position of a leading developer of ecological log house construction and laminated log technology in both the domestic and international markets. Approximately 30 percent of Finnlamelli’s production goes to export, and the main export markets are Japan, Russia, and the United States.



Talliosake identified the need caused by the changing society and created a fast-growing offering of functional and flexibles premises to respond to the demand from companies, consumers, and municipalities desiring to become more attractive locations. Talliosake multifunctional premises are also an interesting option for real estate investors looking for alternatives to investing in residential buildings. The first construction projects in Sweden based on the Talliosake concept were launched in March 2018. Talliosake utilizes big data and artificial intelligence in its operations and marketing. 


PohjanGeo and PohjanTeko

PohjanGeo and PohjanTeko expanded in just a few years from local companies to where they now have a nationwide presence, and by combining earthworks and construction planning services and engineering, they created new and reliable design, contracting, and pricing models.
