There is a growing need for affordable spaces for young working people. In many big cities of Europe, prices per square meters are rising, what forces young professionals to rent a questionable quality, temporary flats, or push them to outskirts. In this work I will investigate a strategy called Klusflat and prove that this strategy can be used to bring an affordable, quality spaces for young people. In the following paragraphs some Klusflat case studies are researched. First example is Kleiburg, one of the most famous Klusflat example. Second one is Klarenstraat block in Amsterdam, the third is a housing unit in Rotterdam. In a conclusion I compare different approaches observed in my case studies. I also give an answer if this strategy can be adapted to solve a problems of not affordable, and not valuable spaces for young professionals
