Disruption of a Green Apartment
Architecture education should focus on imagination, creativity and teamwork only Teach music, sports and arts Music and arts to help our architects to be more creativity and imaginative Sports to make our architects know what is teamwork The future on a Green Apartment is not about competition of knowledge
BUT,
wisdom and experience
