The renovation of the buildings and green areas of the Kultaranta estate was completed on 31 October 2024.
In the first phase of the renovation in 2018–2019, the access roads and infrastructure were renewed. The main phase of the renovation was carried out in 2022–2024 and focused on the garden and the Granite Castle, the main building of the estate. This phase also included renovations to the villas and other structures in the park.
The park and the main building date from the 1910s and 1920s and were in need of renovation. The Kultaranta estate was last renovated in the 1960s, at which time the park was also extensively redeveloped. The granite castle underwent minor renovations in the 1990s.
President of the Republic of Finland Alexander Stubb and his spouse Suzanne Innes-Stubb will be staying at Kultaranta for the summer of 2025. During the summer months the garden at Kultaranta will be open to the public as usual.

The restoration and renovation measures were guided by conservation regulations. Kultaranta was protected in 1994 by decree and in 1987 by a local town plan. Kultaranta is also a classified as a protected built cultural environment.
