Renovation of the Mäntyniemi residence

An extensive renovation of Mäntyniemi, the official residence of the President of the Republic of Finland, began in March 2024. During the renovation, the State Guest House in the Munkkiniemi district of Helsinki will serve as temporary premises.

Mäntyniemi, designed by architects Raili and Reima Pietilä, was originally inaugurated in November 1993. The buildings and surroundings of Mäntyniemi are protected by a town plan adopted by the City of Helsinki in 2021.

Objectives of the renovation

Mäntyniemi was designed as a synthesis of the arts, where the buildings, grounds, interiors, tableware and artwork form a carefully considered whole. The renovation will respect the original design of Mäntyniemi.

One of the aims of the refurbishment is to improve overall energy efficiency, and the project will therefore include the construction of a geothermal and solar power plant. According to a building condition survey carried out prior to the renovation, the main building is generally in good condition and has retained its original appearance. However, the building services will be upgraded and the ventilation equipment will be replaced with a new system.

The main changes include the construction and replacement of lifts, the extension and refurbishment of the gatehouse, the conversion of the outbuilding into offices and meeting rooms, improvements to gate areas and traffic management, the upgrading and replacement of security systems and the refurbishment of furniture and lighting.

In the outdoor area, the most significant changes will will be made to the adjacent Päiväranta plot donated by the City of Helsinki. The project includes the construction of a fence, the installation of security systems, the development of traffic infrastructure and the construction of a service road, a carport and a waste room, as well as other earthworks.

The renovation of Mäntyniemi began in March 2024 and will be completed in spring 2026. During the renovation, the State Guest House in Munkkiniemi will serve as temporary premises for Mäntyniemi.
