Chile. Alejandro Soffia designs a Shotgun house with SIP panels

The building is part of a series of nine houses, an experiment with prefabrication to produce different spatial and volumetric results.

The Shotgun house in Cachagua is the ninth of a series of residential buildings resulting from Alejandro Soffia’s experimentation. The building system features structural insulated panels – also called SIP. In this particular case the architect applies this system to the typology of the Shotgun house, a traditional US residence mainly consisting of a linear arrangement of rooms with a door at each end of the house.

The SIP panels building system combines structure and thermal insulation and serves as a module defining the dimensions of the construction. The distribution of the panels is indeed optimised to compose a series of 33 bays on the same axis, measuring 40 meters in total. The building is divided in two residential units where the double-height living areas are the cores around which the interiors are organised. In each unit, a suspended walkway in the living areas connects the rooms at the first floor emphasising the verticality of the pitched roof with whole-wood coating.
