Kaivoshuvila – A Valuable Cultural Heritage Site Adapted for Year-Round Living
Kaivoshuvila, located on Koirasaarentie in the Laajasalo district of Helsinki, is a rare example of late 18th-century gentry residential architecture that has remained remarkably intact within the built heritage of the Helsinki region. Originally constructed as the residence of a mining blacksmith, the villa dates back to the 1770s–1780s and features a characteristic Karoliner floor plan, a mansard roof, and traditional red ochre-painted timber cladding.
The building is protected under the local detailed plan with the designation sr-1 and is part of a nationally significant built cultural environment (RKY) area known as the “Helsinki Steamship Route Villa Settlements.” All repairs and alterations must respect the historical values of the building, as outlined in the architectural heritage report and in close consultation with the Helsinki City Museum.
Our architectural firm has been responsible for designing the conversion of Kaivoshuvila from a seasonal villa into a permanent single-family residence. As part of this transformation, a portion of the attic floor is being converted into a heated space, incorporating renovated wet rooms, a utility room, and a technical space. Restoration efforts prioritize the retention of original materials and structures, such as the vertical slat cladding and multi-pane windows. The villa’s decorative porch details and ornamental eave trims further reflect its layered architectural history.
The immediate surroundings will be complemented with new wooden fences painted in traditional red ochre, designed to provide both visual screening and continuity with the site’s historical context.
Kaivoshuvila is a prime example of how historically significant architecture can be sensitively adapted for modern living while preserving its unique character and cultural value.
