You always perceive with all your senses. Visually, the clarity and transparency with the surrounding nature were first impressions, it was just spring. Olfactory, I remember green, woody and natural notes.
Fragrance is an essential part of architecture. It makes perfect sense to think about how we perceive a space. Because as long as we breathe, we smell and as long as we smell, fragrance has an impact on our well-being and how we behave. We can control scents, so we can change how things are perceived in space.
