What is Design, Aesthetics & Beauty
1. What is good design? 2. How do we do it? 3. Where does it come from?
What is Design? Creating New Worlds / Envisioning & Evolving the Future
“We shape our buildings, and afterwards our buildings shape us.”
- Winston Churchill

“We see a retrofitted and expanded Aiken Center that provides needed space but has a
smaller ecological footprint, uses
natural lighting, and has pure air and
ecological elements, including water and plants, in its corridors. The Aiken Center
should be the first institutional building at
UVM that beautifully celebrates life within. We envision a year-round
greenhouse and native landscaping, with state-of-the-art energy and water conservation and air circulation. The Aiken Center will be a place
like no other and represent a harbinger for our future.”
