Green Line House, Poland

Natural, esthetic and award winning

The Green Line House in Warmia, Poland designed by Przemek Olczyk from Mobius Architekci Warsaw, won the Grand Prix in the European Property Awards 2019-2020. We are proud that our Swisspearl roof panels are part of this seminal building.

The International Property Awards are one of the most important awards of the commercial real estate industry. For over a decade, a jury of over 80 professionals led by the House of Lords have been awarding investors and architects for the best architectural projects from around the world. In the end the Green Line House won the jury with its natural esthetics.

This solitary house remains lonely in a landscape, without adjacent buildings, away from roads. Harsh landscape prompted Przemek Olczyk, an architect and the author of the project, to use transparent and legible tectonics, thus embedding the building in the morphology of the plot.

Skilful adaptation of the architecture to the structure of the plot ensures that the scale of the 500 sqm house does not overwhelm it. Due to the strong winds in this part of the Warmian Lake District, the design employs an atrial layout. The screen of glass walls of the building provides a transparent shield while maintaining important viewing axes for the users.

The layout of the building in the form of the letter “L”, in turn, reproduces the traditional organization of farm space in the Warmian-Masurian Voivodeship. The façades – mostly glass-walled – are supplemented with aluminium plates and ceramics. The whole is complemented by a wooden lamella detail in the gable walls, thus making a clear reference to the gables of the Warmian-Masurian cottages often decorated with boards arranged in various patterns. The simplified form of the roof with a 45 degree slope and the black Swisspearl roof panels also refers to traditional rural buildings.

A detail of the roof part is a vertical skylight, which asymmetrically divides the slope by opening the interior of the private zone to the surroundings. The roof of the building is mostly covered with Swisspearl roof panels and grass. Only from the side of open atrium concrete slabs were used. This is an aesthetic device designed to emphasize the modern nature of the building.
