Architecture, Building and Structure Design Loop by Loop Private Apartment Building by Frank la Rivière An abandoned concrete building shell, acquired with the intention to create a large apartment for private habitation. The developed design strategy makes use of the unfinished state and the exposed concrete is regarded as a neutral backdrop against which the spaces for habitation are designed. Therefore, finishes contrast with and wrap the concrete only there where needed. Concrete was erased to allow for loop-like structures to be inserted. On these loops life takes centre stage. Executed like freestanding pieces of furniture, each is finished in a different material.
