The Casa Sperimentale is in an increasingly fragile state. Increased vandalism has opened the structure up to the weather. Metal corrosion on the main structural members connecting the concrete superstructure makes it more difficult to visit and survey the building with traditional methods. As the Perugini family improvised during the design and building phase there was no actual drawing record of the complete structure in the context of the site and the surrounding trees.
The relatively high levels of accuracy, combined with photogrammetry, enables detailed virtual modelling of entire buildings with millimeter precision, recording appearance and form as one. This level of detail enables more precise coordination and pre-planning of conservation efforts by allowing specialists to make useful preliminary assessments of material conditions before visiting site, as well as more effective coordination of equipment and machinery with regards to access.

Given the complexity of the Casa Sperimentale’s three-dimensional form, standard survey methods of photography and linear two-dimensional measurements would not have provided the certainty needed to be able to make reliable off-site assessments.
In a parallel sense, the level of access provided, combined with accuracy, enables a new degree of digital dissemination of architecture, rivalling the impact of architectural photography. The existence of a comprehensive digital model enables unprecedented access to the principle logic and form of the Casa Sperimentale to any number of viewers simultaneously, whilst protecting the existing building from further deterioration due to increased visitation by the survey teams as well as the public.
In this way, the 3D Scan serves as a preservation document, a comprehensive record of the building as it exists today-including, for better or worse, its dilapidations signs of wear, abuse, material fatigue, but also its endurance and the finer aspects of its weathering.
The 3D scans were made by Thomas Parker.
