The project's distinctiveness lies in the challenge of preserving the architectural and cultural identity of Cartagena's historic centre while introducing elements and solutions that improve comfort conditions with the lowest possible energy consumption.

The introduction of bioclimatic courtyards and vertical and roof gardens are the most significant features of this project. These solutions passively regulate indoor comfort conditions and reduce energy demand, integrating into an old-town building without altering its character.

A refurbishment that proves heritage conservation in a historic centre and energy efficiency can go hand in hand: a building that retains its cultural identity while delivering low-energy comfort conditions.
