House Riihi / Mies Prize nominee

posted on November 24th 2014 in News

We are happy to announce that House Riihi has been nominated amongst the projects for the European Union Prize for Contemporary Architecture – Mies van der Rohe Award 2015.

Launched in 1987, the European Union Prize for Contemporary Architecture – Mies van der Rohe Award is one of the most prestigious acknowledgments for European architects.

Funded by the EU Cultural Programme and the Fundacio Mies van der Rohe (FMvdR) – Barcelona, the biannual prize gives credit to professionals who are developing the architectural practice through new ideas and technologies, to build better spaces and cities.

Kärsämäki Church and Kuokkala Church were selected as shortlisted projects respectively in 2005 and 2010. We are glad to see the work of OOPEAA nominated once again as a candidate for the prize, this time with the House Riihi, a single family house situated in the midst of the traditional farm landscape of Ostrobothnia.

House Riihi_Jussi Tiainen_04

House Riihi is located in a valley-like area next to a small island of forest on the side of a farm field. The view of the valley with the field has a strong presence in the house and the buildings are organized in a traditional manner around an inner yard so that they give shelter and frame vistas into the landscape. The house blends in with the surrounding nature through its shape and the materials used. Its exterior, interior and frame are all made of wood. Compressed wood has been used for insulation and paper has been used for sealing. The objective was to create a healthyand ecological building that can be recycled when it reaches the end of its life cycle.

The wood is felled from the local forest and the house has been built in close collaboration with skilled local craftsmen making use of the traditional methods of building, applying their knowledge for example in the construction of the four heat retaining fire places that can be used to provide hot water to the house and to heat the house even in the cold Finnish winter weather. The wood in the exterior parts has intentionally been left untreated in order to allow it to naturally turn grey over time. All metal parts in the building are made of untreated aluminum produced in a local factory nearby. The lighting system in the house is supplied with batteries that are charged with solar power. It is possible to live in the house without being dependent on the power grid and on the water and drainage grids. The house is a low energy building. Creating a dialogue between the local tradition and a contemporary approach, it offers a natural framework for sustainable living.

Konsthall Tornedalen in progress

posted on November 5th 2014 in News

In 2012 OOPEAA, operating under the name Lassila Hirvilammi Architects at the time, won the competition for a new art museum in Vitsaniemi in the Swedish Lapland.

The Konsthall Tornedalen will be located on the beautiful banks of the river Kemijoki that marks  the border between Finland and Sweden.

With the design phase now under way, the building is scheduled to be completed in 2016.  Some days ago Gunhild Stensmyr, the commissioner  of the future Konsthall, visited the OOPEAA office in Seinäjoki to brainstorm with the architects about the project and to earnestly kick off the first phase of the design process The meeting was  filmed by the Swedish TV, SVT which is making a documentary on the project.

The meeting provided an occasion to discuss more deeply the preliminary designs for the Kunsthalle. Anssi Lassila, the architect in charge of the project, and Gunhild Stensmyr gathered together with our assisting architects, Ransu Helenius and Kazunori Yamaguchi, and our landscape architecture consultant, Tommi Heinonen from VSU, to study the first models and  the preliminary drawings and to discuss technical solutions.

You can follow the progress of the project on the blog for Konsthall Tornedalen here:

Forum HolzBau – Nordic Wood / Trondheim

posted on September 25th 2014 in News

In these days in Trondheim (NO) technologies and potential in wood construction are discussed at the Forum HolzBau / Nordic Wood, the Nordic Wood Building Conference (24-26 Sept 2014).

Entitled “Wood Future”, the event aims at discussing how traditional knowledge and natural resources can be turned into keys for future building, using wood structures to shape the future, sustainable city.

The construction sector is a major operator on the world economic stage. As its importance is growing, so are its challenges, particularly the increasing demand for material and energy efficiency, as well as the need to reduce building costs.

Professionals within the building construction sector are every day faced with the need to develop and improve their knowledge of materials and their use. Existing buildings are everywhere in constant need of renovation and upgrading to meet new regulations. The use of wood is an important part of the solution.

With its strong expertise in wood architecture and striking references using wood as solely structural tool, OOPEAA could not be missing.

Indeed, tomorrow Anssi Lassila will take part to the parallel session 4A “Excellence of wood / Competitions in wood: from sketch to finish”. From 10:00 to 11:30 and moderated by Tine Hegli from Snøhetta, the guests will discuss about the challenges that wood buildings impose to designers, proposing case studies of successful implementation.

OOPEAA´s projects as Kuokkala Church, Sauna Tonttu, or the recent and still ongoing Puukuokka multistorey housing block show peculiar approaches to wood construction, where carefully thought out choices of material make the difference and make the project become long-lasting architecture.
