A modest piece of land on the edge of a forest, on the very outskirts of Liberec. Gentle south-eastern slope, shade of tree tops and view of the Ještěd ridge. Ideal place for building a family house. As long as one does not look at the zoning plan. The strictest ratio of built-up area in the entire plan, only seven percent, determines the maximum footprint of the house to be just under one hundred square meters, while the more romanticist requirements in their turn prescribe a gable roof, height and aspect ratio of the house. The long-window house is our answer to building a contemporary and gracious home for a young family, even within the unforgiving confines of the zoning code.
