Architects Lederer Ragnarsdottir Oei have been specialized in architecture for more than three decades, consistently adhering to the guiding principle: "First the city, then the house." This involves the following key issues: How can a new building be integrated in such a way that the district also benefits from it? How can it be made to interact optimally with the city? In what ways can it improve the urban qualities of its particular location? As a result, they create trend-setting and forward-looking buildings, which distinguish themselves not only by their architectural standards, but also by their sensitive interaction with their architectural and cultural contexts. Lederer Ragnarsdottir Oei also examine the qualities of existing buildings and translate them into a modern form language. The use of robust and high-quality materials ensures that the current requirements for resource-efficient and sustainable architecture are met. This publication documents the successful creative work of one of the best-known German architecture offices, through 46 completed projects in the areas of residential, commercial and institutional architecture.
