Dear Master, I read of the importance of having square or rectangular bedrooms to provide stability and good "Qi" movements. As I am planning to do some renovation works, I am exploring the option to build a partition and 'create' a more separate rectangular bedroom for my sleeping area. However, I am concerned about ventilation and mobility issues if I were to seal up part of my room. Furthermore, Feng Shui is also about functionality and I was wondering if there are other ways to circumvent the problem of the irregular shape of my bedroom. I do have an attached toilet and a small path leading into the room. For easy reference, I have attached a rough sketch of my planned design. Hope to hear your views on this. Thank you. ?
