RS29 is a minimalist house located in Heidelberg, Germany, designed by Ecker Architekten. The former cafe space was a meeting space for the local art scene back in the 1950s, and is now the resident and office of Ecker Architekten. The architects bought out the building out from being sold to the developer in 2003, and renovated almost a decade later due to the fact that they were so busy with other projects throughout the years.
