When assessing commercial sites, each business space has their unique features. What you do for a restaurant is different to the needs of a corporate company. Depending on the type of business, the feng shui is assessed accordingly.
I have had the opportunity to do the feng shui for small business, corporate companies, holistic centres, hairdressing salons, medical suites, homeopaths rooms, factories, retails stores, business schools, shopping malls and even race horse stable. As long as it has a roof it can be feng shui’d!!
