Renovation & Retrofitting
Breathing new life into what already stands: the schist-village revival of Cerdeira in the Serra da Lousã, cork insulation from Amorim, and bio-architecture studios like Terrapalha. Renovation as the lowest-carbon way to build.

Renovation and retrofitting in Portugal
The greenest house in Portugal is usually one that is already standing. The interior is full of stone and schist buildings that were left empty when the village emptied, and bringing one back costs a fraction of the carbon of a new build, though rarely a fraction of the patience.
Cerdeira brought a whole schist village in the Serra da Lousã back into use. Terrapalha renovates with natural materials out of Sintra, Aresta Engenharia works on bio-construction and urban rehabilitation from Chaves, and Amorim supplies the cork insulation that solves most of the thermal problem in these walls.
Expect damp, no insulation and a roof decision in year one. See also natural materials, eco-building techniques and energy efficiency. Dated activities from these projects are listed in our events calendar.
