英文简介：

How can homes be upgraded to meet today’s demands – from living comfort to energy efficiency and digital requirements? How can the fusion of the historic and the new be used as a design element? The use of existing residential buildings scores not only with the charm of what has been handed down, be it a baroque villa, a 19th-century farmhouse, or a post-war bungalow, but actually also always with an excellent ecological balance. The extensive reworking, whether modernization, renovation or extension, is a widespread and thoroughly rewarding task for many architects. Since the initial situation is documented for each of the presented projects, the reader can clearly understand the redesign process.
