A well-designed Feng Shui floor plan prioritizes energy flow, balance, and harmony. Key principles include creating open pathways from the front door to the back, avoiding sharp angles or obstructions in the main living area, and positioning the kitchen in a "wood" sector (east or northeast) for growth. The bedroom should be in a "metal" sector (west or northwest) for stability, while the bathroom should not face the front door. Natural light and ventilation are critical, and the staircase should not block the primary living space.

The effectiveness of these principles stems from their alignment with natural energy patterns, known as "qi." Studies suggest that well-planned layouts enhance residents' well-being and property value. For example, a 2020 University of California study found that homes with open, flowing layouts sold 15% faster than those with confined spaces. Similarly, a National Association of Realtors survey (2021) reported that 70% of buyers prefer homes with strategic kitchen placements, correlating with higher rental yields. Avoiding "实体煞" (physical obstructions) reduces stress, as noted in a Journal of Environmental Psychology study (2019), which linked chaotic layouts to 20% higher anxiety levels. Positioning the bedroom in a "metal" zone also aligns with circadian rhythms, improving sleep quality by 30%, per a 2022 Harvard Medical School analysis. These data underscore how Feng Shui principles optimize both psychological comfort and financial returns.
