Self-employed builders' campaign
Ratkon Oy offers self-employed builders free building plans (building permit drawings)!
Anticipating the law change that will enter into force in 2025, we offer plans for basic functional buildings at no charge. The change in law enables the construction of small yard buildings under 30 m² and roofs of 50 m² without a permit. Qualified designers and work management will be required for the projects, just like today, but there is no need to obtain a permit.
If you are considering building something larger, these also serve as an example of our company's quality level.
The permit drawings campaign is valid for the time being, but please contact us if you need the design of load-bearing structures or the responsibilities of a person designated for construction supervision for your project!
