The project ' Villa Rotterdam ' is the conversion of a villa located in a green suburb of Rotterdam , using a specific formal and structural strategy to accommodate new programmes within a very limited footprint extension . The villa was composed of an original building from the 1920 s with a set of extensions growing between 1992 and 2005 ; the year that the current owners moved in . Ooze architects translated the owners ' desire to recycle the ' soul ' of the house and to open the house towards the natural elements , the canal , the forest and the garden around it by proposing a new typology : an envelope generated by the local regulations combined with intuitive rationalism , which would wrap up the new programme under one ' hat '. Folds and facets within the maximum allowed envelope connect the new spaces to the existing ones . Beyond style or architectural aesthetic , the generated form engages a rediscovery of the vernacular exploring a new language which reinterprets the old . The envelope ( façade and roof ) is built with solid wood construction structural panels and is clad with back stained sustainable wood planks , frameless glass panels and a grass / sedum green roof . The inner face of the solid wood panels has been whitewashed to give a softer and lighter feel to the internal finishes .
