Not long ago, there was an article in Toronto Star reporting that David Thomson, chair of global media company Thomson Reuters, also considered Canada's richest man have bought a historic property next to his own house and building a two-stored addition connecting the two properties. It was reported that his neighbours are curious, some concerned!
I have read this article with a lot of interests especially when I am considering about the feng shui implications for this decision. First of all, I have suspected that Thomson does not believe in feng shui or has not seek any advice from a feng shui consultant especially from a consultant who practice Xuan Kong Flying Star feng shui. The reason I am saying this is under Xuan Kong Flying Star feng shui, it is not auspicious to connect two houses together to form a large house. This is due to the fact that each house has different facing direction which means a different natal chart. Furthermore, from the picture in the article, we can see that one building is a historic house and his house has a very modern design which means most likely different House Period for the two houses. For instance, one house may be a Period Five house and the other is a Period Seven house. Furthermore, there will be other concerns once we know where the new entrance is located; however, without further information about the actual layout plan, I am not able to discuss this issue here.
Anyway, by joining the two houses together will definitely create the scenario of mixing two different chi pattern together, this means the chi pattern of the new house is not "pure" [氣雜] under the concept of Xuan Kong Flying Star feng shui, which implies unstable feng shui conditions (refer to the following diagram).
Therefore, my prediction is things may get "unsettled" both at home or at work when he moved into the new building. Nonetheless, this is not a difficult feng shui deficiency to fix, any consultant who practice authentic Xuan Kong Flying Star feng shui can solve this problem without any difficulty!
