Lara Calder Architects’ prefab parasite project is meant populate the unused spaces found in urban landscapes. Fittingly, the parasite will cling to old facades, rock faces and even bridges as a way to “achieve sustainable densification.” Designed using a parametric 3d modelling software, the form is a flexible entity as all components, such as the structural system, facade, cladding, floor levels and stairs are integrated into a sole parametric model. The integration of the design system increases efficiency and accuracy of the construction process.
A mounting plate is attached to the back wall where the parasite will attach. Floors are added and lastly, the structural façade is put in place to provide lateral bracing to the form. One the first level, the building contains the main entrance and the study. The bedroom and bathroom are on the second level and the main room has access to a balcony which is protected by a privacy screen. The upper floors contain the living space, kitchen, and small roof terrace, which provides the opportunity for natural cross ventilation.
The project is accessed by a retractable staircase so as not to disturb pedestrians or light vehicular traffic. In addition to not disturbing the street, raising the building 3 to 4 meters above the ground level makes a footprint that “technically only consists of the stair landing and the services duct.”
