Stockholm-based Full Scale Studio of KTH School of Architecture have designed and built their first project to date -- a new studio space called "The Friggatto." Deriving its name and form from the hybridization of two Swedish building types, the Friggatto is a non-permit, rolling house that explores how to combine these typologies to produce a larger, more affordable volume.
The Friggatto fuses two common low-cost housing typologies - the Friggebod and Attefallshus - into a two-part building that, when attached, results in a 40 square-meter space. The larger portion, the "Atto," consists of a 25 square-meter, two-level, open studio constructed from repurposed and affordable materials. Among the materials used are reclaimed mahogany flooring, pine plywood sheathing and roofing, and a burnt wood facade that provides chemical-free weather resistance. On the upper-level, the space beneath the floor is utilized for storage.
Supplemental to the Atto is the "Frigg," a 15 square-meter movable "vehicle" constructed on wheels. It also utilizes upcycled materials to minimize costs, including flooring made from gifted leather and a lightweight structure system of Styrofoam insulation board faced with fireproof pine plywood. On the exterior, a coating of tar provides protection against the elements. To enable mobility, the Frigg's wheels fit into a network of metal rails, allowing the entire volume to be moved by one or two people.
The detachable building system allows for flexibility in defining the Friggato under Swedish law. Because the Frigg is movable, it can qualify as a "vehicle" for a six-month duration, after which it must be moved or it becomes a "house." If the two volumes remain disconnected with a gap large enough for maintenance, no permit is required and the municipality charges no fees. In addition, the interstitial area between the components enables an outdoor workshop space, and houses a staircase for access to the rooftop terrace.
Because the Friggatto employs mainly salvaged materials and bypasses permitting requirements, its costs totaled 4,000€, roughly one-third of the construction costs of Sweden's typical low-expense housing directed by a contractor.
