Vlaardingen Renews Flats Instead of Building New

Why this is here: KAW estimates that the combined surface area of unused garage boxes in post-war neighborhoods is large enough to build a city the size of Groningen.

In Vlaardingen, Netherlands, KAW architects are working with Waterweg Wonen housing corporation and residents to renovate a 1952 portico flat. The building, constructed with MuWi blocks, is receiving new insulation, balconies, and heat pumps to replace old central heating systems. Residents can also opt for internal renovations to expand kitchens or bathrooms.

The project aims to add roughly 200 social housing units and more green space by 2035, all while minimizing demolition. KAW calculates that existing underused spaces in post-war neighborhoods—like garage boxes—could accommodate a city the size of Groningen. They published this finding in their 2020 study, Ruimte Zat in de Stad.

While roughly 75% of residents approved the plan, some oppose it due to concerns about disruption, demolition, or potential rent increases from internal renovations. Communication with residents remains a challenge, and the long duration of the project causes frustration for some. The work continues as planners seek to maximize the potential of existing urban areas.
