About the building
Casa Batroun is a renovation and extension of an old sandstone private house in the seaside town of Batroun in the north of Lebanon.
The objective was to double the existing surface area in an exemplary eco-friendly way, demonstrating that this is possible in a country where the tendency has often been to destroy old heritage and replace beautiful living spaces with characterless concrete high rise buildings. On their own initiative, the owners requested an eco-friendly house from project at the outset, and Casa Batroun achieved BREEAM Excellent certification (PCR certificate obtained in February 2014) in order to serve as an exemplary renovation in a country where sustainable construction is far from being standard.
“Casa Batroun was renovated & built following all the BREEAM International criteria. This important guideline helped steer the project throughout the design phase as well as the construction phase, but it also extended into he living phase where the clients respected the design decisions to resources, enhancing them with their eco-friendly lifestyle.” Maha Nasrallah, Architect
