Situ Fabrication consulted on the fabrication system and material
selection of the dollhouse, which is composed of a welded steel frame clad in
an elastic fabric membrane. Half of the faces of the triangulated form are
hinged and can be smoothly opened and closed with the assistance of gas
springs.
The form of the Dollhouse is produced from the shift and
rotation of 4 rectangular floorslabs which are connected by triangulated faces.
A series of parallel steel mullions within each face further stiffen the
triangulated frame while also providing support for the acrylic glazing. Once
the general structural concept was established, Situ Fabrication produced a
parametric model within Rhino’s Grasshopper interface in order to maintain
flexibility over the developing design as well as to facilitate with part
production. The positions of each floor slab, as well as all of the steel
member dimensions, were parametrically defined allowing us to easily
incorporate changes specified by the architect and structural engineer.
The Grasshopper definition also produced a numbered layout
of each of the unique steel members. A CNC milled plywood welding jig was
generated from the same parametric model to ensure accuracy throughout the
welding and assembly process. To assist with the fabric, Situ Fabrication contracted
Sunnie Joh, who utilized both traditional and contemporary textile fabrication
techniques to create the seamless elastic skin.
