Hermanni Waterfront Park: Open two-phase landscape architecture competition

suomeksi

Hermanninranta Waterfront Park

Open two-phase landscape architecture competition

First phase competition period 15 September 2025 – 15 December 2025
Provisional period for the second phase of the competition May 2026 – September 2026

The City of Helsinki is organising an open two-phase competition for the design of Hermanni Waterfront Park.  The competition is organised in cooperation with the Finnish Association of Landscape Architects (MARK).  The competition assignment is to prepare a design for Hermanni Waterfront Park that will serve as the basis for detailed planning and the implementation of the area.

Task

The aim of the competition is to use means of landscape architecture to develop Hermanni Waterfront Park into an enriching and attractive environment that complements the regional appeal of the Vanhankaupunginlahti nature area and supports the identity of Northern Kalasatama. The aim is to develop a concept based on local conditions and biodiversity that will endure and evolve over time. Much of the park’s existing nature should be preserved to allow it to develop into an increasingly diverse environment.

When designing the Waterfront Park, the sea and the floodwater should be regarded as a part of the area’s unique character. The park should serve both current and future residents by providing well-being and recreational opportunities.

Competition area

The competition area is located in Helsinki Finland alongside the new Hermanninranta district which is currently under development and the future Kyläsaari district, bordering Vanhankaupunginlahti. The Hermanninranta district is not yet built. The construction is expected to begin during the competition period. Hermanni Waterfront Park will serve as a local recreational area for these new neighborhoods.

The competition area, waterfront park, is a naturally developed shoreline that is periodically almost completely submerged. Since the last large-scale landfills in the 1980s, the ruderal vegetation of this former wasteland has grown and matured. The area has gained significant ecological value for urban biodiversity, making its preservation essential. Natural succession is clearly evident, despite the area’s entirely artificial origins.
