[ Lara Calder Architects ] Parasite Prefab

the prefab parasite is to populate the unused space found in urban landscapes. to achieve sustainable densification the dwelling attaches itself to a blank building fabric found in the city.  it grows on empty facades, rock faces and bridges. it finds
value by turning dead public space into lively private space.

the prefab parasite was completely designed using a parametric 3d modelling system. all the components including the structural system, facade, cladding, floor levels and stairs are integrated into the one parametric model. this provides flexibility for the parasite to adjust to the different sites it occupies.

the fabrication and construction rely heavily on digital methods. the facade paneling system is designed and sent to a fabrication to be machine cut out of a sustainable solid surface material. the structural facade members are all controlled parametrically, as are the main structural ribs. the integration of the structure with the design system increases
efficiency and accuracy of the construction process.

the mounting plate which is the back wall of the dwelling is the first component to be installed. the floors and inernal fitout attach to the mounting plate.  the structural facade installed last provides lateral bracing and ties the building together.

the building is raised 3 to 4 meters above the ground level and is accessed via a retractable stair so that the street activity will not be affected.  the actual footprint of the building technically only consists of the stair landing and the services duct.

the first level of the building contains the entrance and the study.  this level is elevated above the ground to allow either pedestrian traffic or light vehicular traffic underneath according to the site.  the study can be closed to the rest of the house allowing for the space to be used as a home office. on the second level is the bedroom and bathroom.
  the bedroom has access to a balcony which is protected by a privacy screen. the living spaces are located on the upper floors with the living room on the third and kitchen and dining on the fourth.  the small balcony off the kitchen provides a space for a potted garden and the roof terrace opposite allows the occupants to enjoy private outdoor space. sliding doors to protected balconies and roof terrace provide opportunity for natural crossventilation across each level which is necessary for cooling.
