House Direction Analyzer (房屋朝向)
Enter information
How to use
Enter birth year + gender
Gregorian year. Male/female trigrams differ (traditional binary algorithm).
Measure house facing
Stand inside main door, face outward. Use compass / phone compass. 8 directions (N / NE / E / SE / S / SW / W / NW).
Read person-house match
Life trigram + house facing in same group = excellent; cross-group = poor (can be remedied).
Read sunlight + taboos
Each facing has sunlight characteristics (cold winter / hot summer / morning light / afternoon light); 6 layout taboos to avoid.
House Direction — Critical for Property Buying
House direction is one of the most important property-buying decisions for Chinese buyers (alongside location). The ancient proverb "sit north, face south; auspicious qi comes from the east" reflects a thousand-year emphasis on orientation. This tool synthesizes 3 dimensions:
Dimension 1: 8-Mansion metaphysics
Each person has a Life Trigram (one of 8); houses are also classified as "East-facing" (N/S/E/SE) or "West-facing" (NE/SW/W/NW). Life Trigram + house in same group = auspicious; cross-group = unfavorable (can be remedied).
Dimension 2: Practical sunlight + ventilation
Beyond metaphysics, south-facing (Northern Hemisphere) = maximum sun, driest, year-round comfort. North = least sun, coldest winter. East = bright mornings, dim afternoons. West = strong afternoon sun, hot summers. These are scientifically real differences.
Dimension 3: 6 layout taboos
Both metaphysics and practicality agree: (1) main door must not face toilet; (2) master bedroom must not face kitchen; (3) main door must not face hallway; (4) avoid beam-pressure (no sofa/bed/desk beneath beams); (5) master bedroom not in inauspicious zone; (6) kitchen + toilet in inauspicious zones ("evil suppresses evil").
This tool vs Bagua House Analysis
Bagua House Analysis = full 8-zone auspicious/inauspicious map. This tool = focused "is THIS house's orientation right for ME?" — a purchase decision aid. Use this tool when buying, then use Bagua House Analysis for renovation/layout.
House direction culture in SG/MY/HK/TW
HK luxury homes with "south-facing" command 5-15% premium. SG HDBs with "south-facing sea views" sell for 8-12% above market. Taiwan + Malaysia landed property selection always factors orientation + feng shui. "Unfavorable orientation" homes trade at 5-20% discount.
West-facing units in Singapore run 20-30% higher on air-conditioning
"Sit north, face south" is the standard orientation of ancient Chinese palaces + principal residences. Beijing's Forbidden City's main axis is exactly north-south.
HK Repulse Bay "south-facing + sea view" luxury homes trade at 15-25% premium over equivalent north-facing units.
Singapore HDB "western-sun" (west-facing) units can hit 33-35°C indoor on summer afternoons; AC bills 20-30% higher than other orientations.
East/West house classification comes from "Bazhai Mingjing" (八宅明镜, "Mirror of the Eight Mansions") — one of the most-cited texts of the 8-Mansion home feng shui school. Of 8 facings: N/S/E/SE = "East-facing"; NE/SW/W/NW = "West-facing", matching the same East-Four / West-Four split used for life trigrams.
"East-group lives" (Kan/Zhen/Xun/Li) suit "East-facing houses". "West-group lives" (Qian/Kun/Gen/Dui) suit "West-facing houses". Same-group match has ~50% probability (8 trigrams × 8 facings = 64 combos: 32 same-group, 32 cross-group).
Cross-group couples are ~50% of marriages. Practitioners advise: (1) Match house to the "main breadwinner" trigram; (2) Use feng shui remediation (relocate door, adjust master bedroom); (3) Place master bedroom in both partners' shared auspicious zone.
"Western sun" / "Northern cold" are real estate jargon. Western sun = west-facing (hot in summer); Northern cold = north-facing (cold in winter). Common in HK + Taiwan + Mainland property listings.
SG/MY "western-sun" units have 20-40% higher summer AC bills; some HDB units sell at 5-10% discount as a result.
Top floor + west-facing is the worst combo in tropical SG/MY — 35-38°C indoor in summer. But top floor + south-facing is actually best (year-round ventilation + sun).
Pairs with Feng Shui Luopan + Bagua House Analysis — the complete house-buying + renovation decision toolkit.
Frequently Asked Questions
Bagua House Analysis = full 8-zone auspicious map (used AFTER purchase for placing bedroom/desk). This tool = "is this house right for me?" purchase decision aid (used WHILE viewing). Buying → this tool. Renovating → Bagua House Analysis.
Cross-group couples are 50% of marriages. Options: (1) pick house matching the "main decision-maker"'s trigram; (2) feng shui remediation (relocate door, adjust master bedroom); (3) place master bedroom in both partners' shared auspicious zone. Most important — communication + compromise.
Don't panic. Bazi believes feng shui can remedy: (1) main door direction (modifiable); (2) master bedroom location (adjustable); (3) furniture orientation (rearrangeable). Often hire a feng shui practitioner for on-site assessment.
SG/MY priority: north-facing (no western sun, efficient AC), SE-facing (trade winds, natural ventilation). Avoid: west-facing (intense western sun), top floor + west-facing (35°C+ indoor in summer). Metaphysics + practicality often align.
Yes. Same algorithm: office orientations also classify East/West. But offices are multi-person — recommend matching to the main company decision-maker's trigram.
Personal call. But the practical layer (sunlight, ventilation, AC costs) often matters more than metaphysics in tropical regions (SG/MY). The metaphysics layer is more valued in temperate + cold regions (Northern China, HK, Taiwan).
Yes. Both tools use the same algorithm (based on year last-two-digits + gender). Same person gets the same trigram in both. Difference is at the presentation layer: this tool focuses on decisions, Bagua House Analysis focuses on layout.
No. Even without believing in metaphysics, this tool's sunlight/ventilation + 6 layout taboos are based on practical disciplines (environmental psychology, energy efficiency, interior design). These recommendations stand on their own.
Trigram calculation 100% accurate (traditional algorithm). Sunlight/ventilation follows Northern Hemisphere standards. Layout taboos are bazi consensus. But serious feng shui requires physical luopan + practitioner on-site visit.
