This makes the industrial history of the city the central aspect of the project, from which variables such as ecology and mixed residential, business, commercial and entertainment use emerge that increase the dynamics of the area.
Infrastructure and ecosystems converge in place by providing special treatments for the treatment of rainwater in flood zones, without neglecting the connectivity and continuity of the floristic and arboreal corridors that extend along the proposed paths, complemented by the New urban meadows and green roofs of buildings that favor the arrival of new species and generate a new local habitat that allows the expansion of the anthropized ecosystem.
In a center and limit exercise. The project incorporates parking areas and traffic roads on the edges of the intervention, prioritizing hiking, walking, bicycle lanes and the new robotic bus route that, in short, involves the idea of sustainable transport that interconnects Pedestrians with the different points of the city.
Description of project by Arkkitehdit LSV, Jolma Architects, TUPA architecture, Nomaji maisema-arkkitehdit and Ramboll Finland
The Riihimäki Station Area Master Plan was adopted by Riihimäki City Council on February 4th, 2020. The plan includes land use, traffic planning, and architectural master planning for an area of 80 hectares to accommodate 5 000 inhabitants. The multidisciplinary team comprised Arkkitehdit LSV, Jolma Architects, TUPA architecture, Nomaji maisema-arkkitehdit, and Ramboll Finland.
The Master Plan for Riihimäki Station Area brings together disparate and detached neighborhoods separated by the bisecting railway line. The plan reconciles different socio-economic conditions to create a more egalitarian society in keeping with Finnish values. The master plan has been developed through an innovative design in dialogue process, consulting local communities, businesses, and individuals. During the design process extensive online and live public consultation helped inform and consolidate draft design options, integrating public, cultural and social needs into the fabric and program of the design. A visually clear, accessible impact assessment of the draft proposals formed an integral part of the decision-making process.
The Master Plan fosters community cohesion. The east and west connections across the railway have been enhanced, including improvement of the existing subway and overground connections. Careful consideration of the programming of land use increases interactions between communities living on both sides of the railway. A new multi-functional public service building on the east side incorporates a library, school, daycare, and elderly day facilities in one building, encouraging multi-generational social interaction.
The design area is characterized by three main neighborhoods with distinct identities that are linked through the transport and blue and green networks to make a unified urban environment for Riihimäki.
A vibrant downtown area has been created around the refurbished historical train sheds. The historical buildings in this area have been retained and repurposed to include modern restaurant and entertainment facilities that activate the public open space, support public events, and enhance the 24-hour economy. The historic setting of the existing buildings has been respected in the scaling of proposed buildings and the choice of complimentary materials. City center functions of mixed-use residential, retail, entertainment, and offices bring vibrancy to the downtown area.
The service center in Peltosaari acts as an attractor, providing social and cultural services for people of all backgrounds. The area is well connected through the main pedestrian and cycle network, as well as public transport and car routes.
The townscape character of Jokikylä is defined by the proximity of nature found in the lush meadow and riverside vegetation of the Vantaanjoki river. As well as serving as flood mitigation, the pond provides a tranquil centerpiece for the village of detached houses, townhouses, and terraced housing. The human-scale public open spaces are inward-focused, offering respite from the noise of the adjacent railway.
The eastern portion of the site is sensitive to flooding. The Master Plan provides sustainable amenity space for the community and mitigates potential flood risks through an innovative green and blue network of green streets, public parks, and a stormwater attenuation ponds incorporated into the city structure. Both pedestrian and habitat connectivity are enhanced through a pleasant green ring consisting of species-rich meadow planting, a linear park, and strategically placed pocket parks. The regionally significant Vantaanjoki river is integrated into the Master Plan in the form of a linear pedestrian route and flood pond that attenuates surface water run-off and fluvial flooding.
A key tenet of the blue infrastructure network is the organic management of stormwater. The central stormwater park in Peltosaari provides a large open green space for informal recreation while hosting a series of inter-connected stormwater attenuation ponds that increase the biodiversity of the area through supporting wetland biotopes. Adjacent to the school, a sports park hosts both school and public recreation facilities.
Biodiversity and habitat connectivity are enhanced through the green network of urban meadows, green streets, and green roofs. The high floristic content of the species mix encourages pollinators, supporting a wider ecosystem that extends beyond the design area and includes the local bat foraging habitat.
Cycling and walking are prioritized through pleasant human-scale environments, green streets, and a comprehensive cycle network that extends out of the design area and incorporates safe cycle parking at strategic locations. Sustainable transport is supported by the incorporation of the autonomous robot bus route that integrates the design area into the wider city. Motorized traffic is mostly concentrated on the edges of the design with the central green street providing connections to the railway station. Centralized car parking provides opportunities for multi-use spaces and fosters social interaction while enabling car-free pedestrian-friendly internal spaces.
