Forget crystals and bamboo flutes.
Feng Shui, in its technical essence, and modern Neuroarchitecture deal with the Psychology of Space and Cognitive Ergonomics. A buyer decides if they like the house in the first 10 seconds. This decision is instinctive and based on how the brain "reads" the environment (security, control, flow).

Practical Application in Pre-Sales:
Command Position: In the living room and bedrooms, we ensure that the sofa and bed are positioned so that whoever is there can see the door (survival/security instinct), but is not in a straight line with it (draft/stress).

Unblocking Flows (Chi): We remove physical obstacles in the hallways. If you have to dodge a table to cross the room, the brain registers "tightness" and "conflict".

Yin/Yang Balance (Light and Shadow): Very white and bright houses (excessive Yang) cause anxiety. We introduce soft textures, rugs, and wood (Yin) to create emotional comfort.
