Durability make sure stuff works and is built for future generations.  Outsmart and outlast both designed and perceived obsolescence.

Sensibility continually assert discipline in size, scale and program.  Know when to subtract and streamline.  Beauty and comfort result from intelligent solutions, not the reflexive addition of  features.

Density incorporate the most people and activities that can sensibly be sustained in a given volume.  There is a healthy balance between lawn covered neighborhoods and asphalt encased towers.

Timelessness understand what forms and innovations will last; reject fashion, pretention, and conscious efforts to attract attention.
