This is a small Swedish firm called Byggfenomen (BuildPhenomena) that produce some really interesting projects.
The firm is one of the few Swedish firms working extenstively with concrete in Sweden, where concrete buildings are rare. Here is an article on a renovation they made to a barn to convert into a holiday house. Notice how the problems they faced with the swedish clients demanding timber was converted into some of the more interesting aspects of the house, for example the exterior wall is not timber anymore. It is conrete molded to a pattern of timber and painted to blend in with traditional swedish housing.
