This last year I have been exploring different approaches towards sustainability in architecture and interior design, trying to define the term itself and understanding its boundaries in our modern way of building. This project summarises what I found to be the key elements of the practice of sustainable design. My focus has been on the deep entanglement between sustainability and time, causing me to question the concept of monumentality in architecture and associating the term sustainability with flexibility instead. The next few years will hopefully allow me to continue discovering and studying holistic and durable design practices that encourage a more sustainable application of architecture, design and urban planning.
