Casa Sperimentale

Designed by Guiseppe Perugini with Uga de Plaisant and Raynaldo Perugini, Casa Sperimentale (also known as Casa Albero, Treehouse) was built on a large, well-treed corner plot in an area of villas within the pine forest at Fregene, Italy. The house was constructed between 1968 and 1975 as an experimental villa for weekend occupation. Fregene, a coastal resort about 30 km from Rome, became culturally prominent in the 1960s and 1970s when it was at the centre of the worlds of cinema and fashion. It was used as a location by Federico Fellini, who shot some of the scenes of The White Sheikh, Juliet of the Spirits and La Dolce Vita in the large pine forest in which Casa Albero was built. Fellini had a summer house there. Photo credits slide show: French+Tye.

From the 1960s, Perugini was among the first to explore the application of the language of computer programming to the design of buildings

History of the building, its design and significance

From the 1960s, Perugini was among the first to explore the application of the language of computer programming to the design of buildings. Casa Sperimentale investigated the possibilities for an architecture of rotating structures and prefabricated elements and was of a deliberately unfinished nature. The house comprised several experimental structures: the house itself, a suspended structure formed of a series of reinforced concrete frames, supporting plates of standardized size, divided by glass inserts with a ground level spa/pool; a sphere of 5m diameter in the grounds, with a bedroom, kitchen and bathroom; and the ‘cubes’, a sequence of three 3x3x3m cubes containing two room and a kitchen, separated by two modules of 3x1.5m for the baths.

The building consists of four elements that can all be considered individual projects and are quite distinct in what they represent and how they there designed.
1. the house
2. the sphere
3, the guest houses
4. the fence

The house is of interest to contemporary architects and was included in the exhibition Bruno Zevi: Zevi’s architects. History and counter-history of Italian architecture 1944-2000 (curators: Pippo Ciorra, Jean-Louis Cohen, MAXXI, Rome, April-September 2018). The exhibition positioned Perugini’s work within the context of architects including Maurizio Sacripanti, Luigi Pellegrin, Franco Albini, Giovanni Michelucci, Mario Ridolfi and Carlo Mollino.
