坤門乾主 延年宅: Southwest Door / Northwest Master Bedroom 坤門乾主 · 延年宅

The pairing of an Southwest-octant main door (Kun, 坤) with a Northwest-octant master bedroom (Qian, 乾) is one of the 64 cells in the classical 阳宅三要 (Yang Zhai San Yao — “Three Essentials of the Yang Dwelling”) door × master matrix. Under 八宅 (Eight Mansions) doctrine, this specific pairing falls into the 延年宅 outcome class.

Classical reading

坤門乾主：延年宅：陰陽正配，夫妻和順，子孫忠孝，福壽齊全。但久居有克妻之應，當留意女主之身。

Classical 阳宅三要 reading for 坤門乾主, in the 延年宅 (Yan Nian) outcome class. Households commonly report stable marriages, durable partnerships, and intergenerational harmony — though the classical text flags a long-residency caveat regarding the female occupant's health. Couples in stressed marriages tend to find this configuration helps; couples in healthy marriages benefit but should be attentive to the female occupant's health register over multi-decade residency.

The classical caveat that applies to this configuration: 久居克妻. This caveat does not always activate — whether it manifests in a specific household depends on the occupants’ personal charts, the building’s period chart, and the year-on-year transit pattern. The caveat appearing in the verse signals the register a household should watch for, not an inevitable outcome.

Why generic guidance for 坤門乾主 fails

The 阳宅三要 outcome class is one of three layers that determine how a configuration actually plays out for a specific household. The other two layers — the building’s 玄空 (Xuan Kong) period and mountain/water chart, and each occupant’s personal BaZi and Zi Wei Dou Shu charts — modify the classical reading substantially. The same 坤門乾主 configuration can read as “auspicious” under one period chart and shift register under another. It can support one occupant’s chart and clash with a co-occupant’s. Generic per-pairing guidance can name the classical register and the most-watched caveats, but it cannot tell you which apply to your household.

The classical doctrine itself is explicit about this: 阳宅三要 sets the foundational pairing, but the household’s actual experience requires the additional layers to read. Master Sean Chan’s blog post on the chart-house interconnection covers this multi-layer reading.

• Read the configuration in context, not in isolation. The 坤門乾主 pairing produces a 延年宅 register at the foundational layer, but the household’s actual experience depends on the building’s period chart, the occupants’ personal charts, and the year-transit pattern. Site-specific reading is required to know which classical caveats activate.
• Pre-purchase audit. If you are evaluating a Singapore home with this configuration before signing the option-to-purchase, a pre-purchase feng shui audit reads the pairing against your personal charts and the building’s period chart, and tells you concretely whether the configuration is workable for your household before contractual commitment.
• Existing-residence audit. If you already live in a home with this configuration, a full residential feng shui audit identifies which of the classical registers are most-likely to activate for your specific household and produces structural / orientation / timing guidance accordingly. The classical caveat 久居克妻 in particular is one the audit will assess against your charts.
• Do not rely on generic feng shui “cures” for this pairing. The retail apparatus around feng shui — six-emperor coins, bagua mirrors, salt-water vessels, talismans — does not modify the underlying 阳宅三要 outcome class. Classical correction for a clashing pairing is structural (entry sequence, master-bedroom usage, room-allocation reassignment) and timing-based (avoid certain transit years for major decisions), not object-based.
