Our modern urban society is experiencing a worrying ‘new’ environmental situation that practitioners of Feng Shui have been cautioning about for thousands of years. We term it ‘Wind Sha'. When I recently conducted students’ study tours at London’s Canary Wharf, it was impossible to ignore the excessive wind that blew constantly, channeled between the awesome high rise buildings that occupy its straight East-West main streets. Many have angular corners, which accentuate thewind force. Now it seems it is no longer only Feng Shui devotees who acknowledge the problem exists.

Wind is funnelled between tall structures and is directed harshly towards any property that faces a T-junction. This is perceived in Feng Shui as a detrimental force that affects occupants, undermining their life situations.

The wind speed and its pressure increase to become unpleasant, even harmful, as demonstrated in this photo of a beautiful lime tree growing in direct line with the gap between two large houses near me that was blown down during last year’s high winds. And the house facing this alleyway also sustained damage.
