Bagua on a Floor Plan
Real homes are rarely perfect squares. This L-shaped plan shows how the grid is stretched over the footprint, where the centre falls, and how a missing area is detected.
Step by step
- Outline the footprint. The union of all rooms forms the home’s outline.
- Find the centre. The weighted centre of the outline becomes the Tai Chi point.
- Lay the grid. For the 9-grid, the outline’s bounding box is split into thirds. Each outer cell takes the compass direction of its position — or, in BTB, its position relative to the front door.
- Check coverage. Any outer cell mostly outside the walls is reported as partly missing.
In the example, the bottom-right corner is open, so part of the plan’s south-east is missing. Switch to 8 wedges to see how the same home reads with radial sectors, or read the full methodology.

Questions
What is a missing area in Feng Shui?+
When part of a Bagua cell falls outside the home’s walls — common in L- and U-shaped homes. Here a cell less than 60% covered is flagged; practitioners vary between about 50% and two thirds.
Where is the centre of an L-shaped home?+
We use the area-weighted centre of the whole footprint. For some shapes it lands outside any room, which is itself traditionally reviewed.
Do garages and balconies count?+
Traditions differ. Many include attached, lived-in spaces and exclude garages. In House Quest you decide by drawing or omitting them.
Can I trace my own plan?+
Yes. Upload an image or PDF, set its scale, and draw rooms on top. The image never leaves your device.
