Rental living reached new heights in Kalasatama, Helsinki. In Lumo One, built by SRV, living space extends beyond residents' own apartments to shared facilities with panoramic views on the 29th floor, while the services of REDI shopping centre are just a lift ride away.
Lumo One, built by SRV, is Finland's tallest rental apartment building and one of the towers in Helsinki's Kalasatama high-rise district. In addition to Lumo One, the completed towers include Loisto, Visio, Majakka and the Horisontti office tower. The planned development of eight towers is the largest construction project in SRV's history.
Built in connection with REDI shopping centre, the 31-storey Lumo One stands over 120 metres tall and contains 291 Lumo rental apartments, offering an alternative to owner-occupied housing. Construction of the tower began in spring 2020, and the first residents moved into their new homes in June 2022.
"To ensure that moving days went smoothly, we reserved a section of the street in front of the building, staggered the moves and arranged for Lumo Homes staff to be on site to guide residents. Some customers also booked a full-service removal service through us," says Laura Koiranen, Regional Director at Lumo Homes.
High-rise construction required specialist expertise
Experience gained from constructing the previous towers made it possible to work more efficiently on site. For example, the time required to construct the structural frame of a single floor was halved compared with Majakka and Loisto. While it previously took two weeks to complete the frame of one floor, the work could now be completed in approximately six days.
The COVID-19 pandemic brought additional challenges to the Lumo One construction project. Guided tours and apartment viewings required more arrangements than usual due to restrictions on participant numbers, protective equipment requirements and coordination. Nevertheless, the project stayed on schedule, and residents were ultimately able to move into their homes earlier than expected.
"Buildings of this size involve large numbers of workers, extensive safety arrangements, complex logistics and various checklists to ensure that the wind does not cause damage," explains Kai Remmler, Director of SRV's High-Rise Construction Unit.
Urban living with panoramic views
Lumo One's apartments are carefully designed, comfortable, high-quality urban homes. Floor-to-ceiling windows offer impressive views, and instead of a traditional balcony, each apartment has its own winter garden.
The 29th floor also features spacious shared facilities, including glazed terraces, impressive sauna facilities and a versatile residents' lounge, inviting residents to cook for friends or enjoy a sauna high above central Helsinki.
"A comprehensive range of residential services will also be introduced to make everyday life easier and more convenient for the building's residents," Koiranen adds.
A lifecycle-wise residential tower
Lifecycle wisdom is reflected in many aspects of Lumo One. The building is Finland's first high-rise to receive BREEAM Very Good certification.
Lumo One has been designed to be adaptable, with lightweight partition walls that can be removed if the apartments need to be modified or their use changed in the future. This solution also helped speed up construction.
The choice of structural frame solutions made it possible to significantly reduce the amount of concrete used in construction. Despite the large footprint of the towers, the building's weight relative to its footprint is lower than that of a conventional building. Careful design also made it possible to further reduce energy consumption in Lumo One.
High-rise construction supports sustainable urban development. Land is used efficiently by building upwards in densely developed urban areas close to good public transport connections.
