Karviaistie 12 residential building block

In 2020–2021, a design competition was held for a residential apartment block located in Ala-Malmi, at Karviaistie 12, where the participants were asked to design a facade stripping renovation project and elevate the buildings with two additional wooden floors. The competition also set ambitious goals for the renovations in terms of improving energy efficiency.

The site is a unit of eight blocks of flats completed in 1977, owned by Helsingin kaupungin asunnot Oy. A facade stripping renovation project means replacing the concrete elements used as facade material with wood.

Four architecture agencies were invited to the competition, and the winner was Architecture and Design Agency Talli together with Architecture Agency A-Konsultit with their proposal ‘Metsä puilta’ (‘Forest from the trees’). The assessment criteria were, in addition to the innovative use of wood material, the solutions’ reproducibility, architectonic quality, positive effect on the cityscape, low emissions and cost effectiveness. The winning entry has the lowest total costs.

Hopealaakso daycare centre

Hopealaakso daycare centre for 210 children will be built in Kruunuvuorenranta. The daycare centre will be completed by autumn 2021.

The daycare centre has two floors and a new design that was presented in an architecture competition in 2019. Wood was the most cost efficient construction material for the project.

The objective was to achieve a four-star rating for the daycare centre in the environmental rating programme run by the Building Information Foundation RTS. The building will feature a green roof with stonecrops.

Wooden parking garage

A project with the purpose of developing a wooden parking garage that meets Finnish standards was launched in March 2020. Using wood in parking garages could help reduce the carbon footprint of construction while also increasing carbon pools.

At the moment, there are no wooden parking garages in Finland taller than two floors, as building taller structures has not been possible due to the national fire safety standards. However, this project aims to prove that building a fire-safe parking garage even without protective plates is possible.

The project’s parking houses are designed in Kuninkaantammi, Helsinki, and Kivistö, Vantaa. These new residential areas have highlighted wooden construction and other, green construction solutions. The parking garages will have green roofs to absorb storm waters and solar panels for producing electricity.
