Feng shui house design should be reviewed as a whole system of entrances, rooms, light, ventilation, privacy, storage, and movement.
Quick answer
Resolve functional conflicts on the plan before using sector labels or decorative remedies.
Start at the site and entrance
Approach, drainage, weather exposure, accessibility, and the transition indoors affect daily use. A symbolic entrance treatment cannot correct a dangerous step or water problem.

Zone noisy and quiet activities
Keep sleep and focused work protected from service noise and busy shared routes where possible. Use doors, storage, and acoustic separation deliberately.

Plan for change and maintenance
Families, mobility, and work patterns change. Preserve service access, flexible rooms, and realistic storage instead of designing only for a staged photograph.

Boundary: Feng shui is a cultural and design perspective. It cannot guarantee health, wealth, relationships, safety, or other outcomes. Use qualified professional advice for building, electrical, plumbing, fire-safety, accessibility, horticultural, or medical questions.
