Prefabrication experiments - 157 - Open Building - 08 - Infill Reversibility


Time based or season based architecture, which varies according to evolving and changing conditions is generally linked to extreme climates. Window shutters or easily assembled temporary structures such as carports or entry vestibules materialize from assembled components to protect us in winter and eventually come down in summer as effortlessly as they arose. Referenced by Bernard Rudofsky in Architecture without Architects as a vernacular example of this time based adaptability, the lemon growing greenhouses (limonaie) on the shores of Lake Garda in Northern Italy portray a simple reversible and adaptable building strategy. Simple planking covers the pergola’s skeletal roof in winter while glazing is inserted in the spaces between the columns to construct a makeshift green house to protect plants. A building that not only adapts but also facilitates changes can heighten its useful service life.   

Programming this type of adaptability is central to open building theory. Applying this type of adaptability to all building systems and functions requires some form of systemic rationalization as well as complete separation of adjacent units; building systems must me designed and coordinated to minimize restrictions between owners and neighbours without disturbing collective infrastructural integrity. Proponents of open building such as Stephen Kendall have explored the separation of supports (invariable infrastructure) and infill (variable fit-out strategies) since the latter half of the twentieth century. Theory argues for systemic mechanical disentanglement by using components and reversible connections that facilitate change by unscrambling systems differentiating individual and collective possibilities. This individualization reduces the risk associated with residential retrofit lessening waste.  


Professor Kendall has explored the practicality of open building theory. His retrofitting kits, Kitfit prototypes, posit infill as building parts that facilitate change within dwelling systems where partitions and MEP systems are completely inter-coordinated and independently assembled for simplifying retrofitting. The Kitfit prototypes utilize elements such as under-floor and baseboard networks to make rewiring and accessing mechanical elements simpler. Under-floor mechanical matrixes also propose a system grid to allow for a certain amount of change to plumbing and ducting. The main structuring element of the Kitfit prototype is based on component reversibility, like the simple glazing units of the limonaie allowing time sensitive architecture to flourish.
