Waanders In de Broeren by BK Architecten is a recently completed renovation of Broerenkerk – a fifteenth-century church – into a shop and café in Zwolle, The Netherlands. With this new function the city of Zwolle maintains this unique cultural heritage site. BK. Architecten made the designs for this project and accompanied the total building process. Their concept of this shop in church is based on two, sometimes conflicting, elements. ‘We wanted all the additions to be sober and modest, respectful to the church. Therefore, the three added floors are placed in the side wing between the original pillars, outside the central strip. The construction of these floors isn’t connected to the church, so in the future the added floors can be removed without demolishing the building.’ With this work the architects succeeded in designing a sustainable and at the same time modern artwork unique.
