Finland’s first 3D property registered in Espoo

The first 3D property in Finland has been registered in Keilalahti, Espoo, when a new parking plot was parcelled underneath the current plot. Residential buildings of 40 storeys have been planned for the area.

The act on the registration of 3D property entered into force on 1 August 2018. The first 3D property was entered in the cadastral register on 9 January 2020. The formation of 3D property requires changes in the local detailed plan, provided that the valid local plan does not enable a 3D plot division.

The aim of 3D property formation is to clarify the ownership of real estate and to make the processes of preparing agreements, completing real estate transactions and allocating real estate tax easier.

The deployment of the 3D property system has been developed since 2006. On 1 April 2015, Arvo Kokkonen, Director General of the National Land Survey of Finland (NLS), appointed implementation and deployment projects to carry out the changes required by the 3D property system in NLS data systems. These were preceded by a definition project, which was completed in 2014.

Years of cooperation behind the new system

The new 3D property system has been built in close cooperation between NLS, municipalities and the Association of Finnish Municipalities. Members of the implementation and deployment project team were the cities of Helsinki, Espoo and Tampere and the Association of Finnish Municipalities. The deployment project coordinated and prepared the progress of the legal amendments required.

Significant changes have been made in the data systems of municipalities to enable 3D plot divisions. Municipalities were independently responsible for these changes.

Development director Pekka Halme chaired the steering group for the projects led by NLS. Responsibility area director Mikko Peltokorpi acted as a project manager in the implementation project and senior specialist Paavo Häikiö acted as a project manager in the deployment project.

The development of the 3D property system started in 2006 when the Ministry of Agriculture and Forestry set up a large-scale working group. Its members were the Ministry of the Environment, the Ministry of Justice, NLS, the Association of Finnish Municipalities, the City of Helsinki and the Helsinki University of Technology (currently Aalto University).
