The Antarctic built environment is characterised for its particular occupational regimen and includes whole-year stations, small-scale seasonal station and refuges,and temporary ﬁeld camps. In recent years,Antarctic construction has begun to be considered of interest for the architectural and engineering communities, and interesting eﬀorts have been made to provide solutions for spanning building, energy eﬃciency and improvements in indoor habitability. A fascinating array of lightweight constructions can be identiﬁed, whose contribution has not, until now, been fully documented and acknowledged. They represent remarkable examples of smart use of structural eﬃciency and minimal impact strategies enduring one of the harshest environments. This research is design-led and is motivated by the extension of the use of lightweight structures in remote fragile areas. The research validates the concept of polar lightweight design through a sound narrative describing the history and potential of this type of construction. For this, this research looks at the case of the Antarctic built environment. Furthermore, this research proposes that extension in the use lightweight construction could oﬀer a sustainable solution for the predicted increase in the number of settlements being established in Antarctica. Knowledge and solutions achieved in this context can also be applied in other less demanding and fragile scenarios. In this regard, advanced computational design tools have been extensively validated for the realisation of structural surfaces of high geometrical complexity. Parametric design tools, are of particular interest to this research, as they allow the optimisation of a structure, either as a whole, or via its physical components. This research proposes that such tools can be employed for the development of Polar lightweight systems of larger scale and more complex conﬁgurations than currently seen. The ﬁrst part is dedicated to the documentation and systematic characterisation of the vernacular Subantarctic and Antarctic lightweight constructions as structural systems. In the second part, the integration of polar constraints in the design of a generic lightweight structural system using parametric design tools is developed, in order to demonstrate the potential of this ﬁeld for the creation of novel design methods and solutions. The particular case of a new medium-scale seasonal station is used as a case-study.
