2Barevné Letňany, which weaved blue and green into the coat of arms, came with flats in low-energy houses to offer those interested a high standard of housing and significant financial savings. In addition to high-quality brick construction, high-quality plastic windows with triple glazing were used in the construction, which significantly reduce heat losses and thus save energy for heating flats. The project proposal focused on modern technologies and other new trends in housing. The construction was carried out between 2012 and 2014.
