Lecture by Anssi Lassila, OOPEAA

The Future of Wood: Back to Basics 


In his talk at the Strelka Institute, Anssi Lassila will share his thinking on the future of wood in architecture and construction. Drawing from his own experience in working with wood, he will look at the material qualities of wood and the ways in which they find expression in defining the structural framework of a building. From the traditional log cabin to the contemporary multi-story housing block composed of prefabricated volumetric cross-laminated timber (CLT) modules, the idea of modularity and the most optimal use of material have always been central in guiding the process of creating a building out of wood. New techniques and new ways of handling wood as a material for building today open up new possibilities in flexibly customized standardization, yet we also have a lot gain from the knowledge embedded in the tradition of working with wood.

The lecture is part of Strelka’s summer public program organized this year under the heading New mindset. Other speakers in the series this year include Steven Holl architects and Reiulf Ramstad, among others.


Strelka Institute for Media, Architecture and Design was founded in 2009 to inspire change in the cultural and physical landscapes of Russian cities. The Institute promotes positive changes and creates new ideas and values through its educational activities. Strelka Institute is a non-governmental institution with an experimental approach to education. Its educational program promotes critical thinking and public presentation skills. Strelka is open to the world and ready for cooperation and networking; all the knowledge produced at the Institute and many of its educational events are free to the public. This openness has turned the Strelka Institute into a popular public space around which various communities are built.

Periscope Tower is now open to the public

posted on July 6th 2016 in News

Periscope Tower_web_01

The Periscope Tower is a giant wooden periscope structure that serves as an observation tower and engages the viewer in a dialogue with the landscape. With the help of a large mirror the Periscope Tower makes it possible for everyone to enjoy the views of the surrounding landscape. One can either climb up the stairs to enjoy the view over the lake and into the surrounding landscape from the viewing deck, or simply stay on the ground and get the view through the periscope mirror.
Made entirely of wood, the building is composed of an inner core of cross-laminated timber (CLT) and an external wooden frame that serves as a load bearing structure. The inner core made of CLT forms the frame for an extra large periscope with stairs circling around it. When taking the stairs up or down one can experience a rich range of different views framed by the various openings cut into the structure.
The tower is composed of three prefabricated elements with the roof forming a fourth element. The facades and the stairs are made of larch. The details and the security netting are of steel. The idea was to create a simple wooden structure of high quality in a way that supports learning and reflects a commitment to empowering and strengthening the local community.

The Periscope Tower is situated on the shore of a man-made lake that has been built on top of a hill in the vicinity of the center of the city of Seinäjoki. The man-made lake, Lake Kyrösjärvi, has been created in order to serve three main functions: to help keep the flooding in the plains of Ostrobothnia under control, to generate energy for the electric power plant serving the city of Seinäjoki, and to form an attractive site for a new residential area to be constructed on the shores of the lake. 120 000 square meters of new housing will be built there to provide homes for about 2000 people. The Periscope Tower is part of a larger landscape design project for reshaping the lakeshore, developed by OOPEAA for the Seinäjoki Housing Fair 2016.
With the Periscope Tower, the aim is to activate the dam around the man-made lake and to turn it into a recreational area serving the residents of the new neighborhood to be constructed there as well as others living in Seinäjoki and the region at large. It will be connected to a broader network of recreational paths designed to be accessible to everyone.

The Periscope Tower was commissioned by the City of Seinäjoki, realized in collaboration with SWECO Seinäjoki and constructed by the students of SEDU, a local vocational school for building and construction skills. It is part of the area developed for the annual Finnish Housing Fair to be held in Seinäjoki in 2016. The Housing Fair is open to the visitors July 8 – August 7, 2016, and the Periscope Tower will remain open to the public to enjoy also after the fair closes.

OOPEAA wins competition for designing a new apartment building in Jätkäsaari, Helsinki

posted on June 15th 2016 in News

OOPEAA’s proposal “Karlsson” wins the invited architecture competition for designing a 4-6 storey apartment building in Jätkäsaari to form a part of the larger entity of block 20828. The competition was organized by Lakea in collaboration with the City Planning Department, Helsinki and SAFA, the Finnish Association of Architects.


Karlsson takes its cue from Helsinki as a city of roof scapes where the rich and varied roofs form one façade of the buildings. The proposal offers a contemporary voice in the long continuum of this tradition. The building is located in the tightly knit new residential area currently under way in Jätkäsaari and is situated next to the Hyväntoivonpuisto Park.

With its structure varying between 3 and 6 storeys in height, the building relates naturally to the scale of its surrounding townscape and allows for creating terrace spaces with views that open up over the roofs towards the park and the sea. On top of the 4-storey high part there is a shared roof terrace with sauna spaces for the common use by the residents. There is also a common space for meetings with its adjoining outdoor areas provided for the residents. The design solution with its varied apartment types allows for flexibility for meeting the diverse needs of the residents in different stages in their life.

The materials used in the façade are slammed brick, glass and wood. The dark glazed brick on the side of the Hyväntoivonniemi Park and on the north side stands in contrast to the white brick of in the façades on the side of the interior courtyard. On the side of the sheltered inner court-yard, the roofs are realized as green roofs and the terraces of the apartments in the upper floors create lively rhythm to the appearance of the building as a whole while the balconies in the building serve to provide external protection from excess sun. Solar panels installed on the roofs are used for heating warm water for use in the building. The building has a recognizable shape that stands out in its surroundings with its human scale and lively character.


The other invited participants in the competition included Casagrande Laboratory Center of Urban Research, Casagrande Architects and MER Architects. Timo Mantila of Lakea served as the Chairman of the jury. Other jury members representing Lakea were Veikko Jokimäki, Technical Director, Juha Kuusiniemi, Regional Manager as well as Juuso Koskela, Project Engineer of Lakea. Kirsi Rantama and Matti Kaijansinkko served as representatives of the City Planning Department, Helsinki. Juhani Maunula served as the representative appointed by the Competition Board of the Association of Finnish Architects.

Puukuokka Housing Block, Jyväskylä 2014 in the Biennial Review

The jury selected Puukuokka to the Biennial Review as a pioneering new sample of wooden architecture. The eight-storey block of flats takes wooden residential architecture to unprecedented heights in both scale and distinctive creative expression. It is a pilot case testing new CLT (cross-laminated timber) technology. Each of the flats is assembled from two prefabricated CLT volumetric modules lifted into place and joined to the stairwell. Puukuokka furthermore represents an innovative residential funding model.
