What feng shui actually is.

Feng shui is a structured way of looking at a room. It asks where the door is. Where the bed is. Where the stove is. Where the light comes in. Where the air moves. Where you sit when you work.

Then it gives you a small number of changes to try.

Some of those changes have a plain, practical rationale. Better light helps you read. A clean stove makes you cook more. A clear path to the door is easier to walk.

Some of them are traditional: the wealth corner, the mirror rules, the five-element pairings. Where a recommendation is traditional, we say so, and we tell you what the evidence supports.

Underneath the schools and the cures, feng shui is a way of reading space: orientation, movement, light, proportion, entrance, rest. My Feng Shui Home reads it that way because the site is written by an architect.

The shortest way in is your Kua number. It names the four directions in your home that traditionally support you and the four to handle with more care. It is right at the top of this page, and it takes ten seconds.

Common questions

Is feng shui real?

Feng shui is real as a structured design method. It looks at where doors, beds, stoves, light, and people sit in a room, then proposes small changes. Some changes are testable design choices. Some are traditional. We name which is which on every page.

Do I have to redecorate?

No. Most useful feng shui moves are tiny. A clean stove. A bulb replaced. A bed turned ninety degrees so you can see the door. The 14-point checklist on this page is finishable in one afternoon and asks for no new furniture.

How is this different from a magazine article on feng shui?

Magazines mix the practical bits with the mystical bits and label nothing. We separate them. You get the structured design version first, the traditional symbolism clearly labelled second, and a clear note on what the evidence supports.

Do I need to know my birthday for this?

Only if you want your Kua number, which keys the personal direction recommendations. The room walkthrough and the 14-point checklist work without it. You can use the whole free site without sharing a birthday at all.

What is the Kua number?

Your Kua number is a single digit from one to nine based on your birth year and gender. It sorts you into an East or West group and names four directions that traditionally support you and four to handle with care. It takes ten seconds to calculate.

Is the site free?

The calculator, the methodology page, the room harmony checklist, and the teaser articles are all free with no account. Saving charts and reading the gated articles is free with an account. The paid guides and tools live on the shop page. The free side of the site is the same site forever - paid content is opt-in.

What is the Personal Feng Shui Compass?

It is a personalised PDF keyed to your Kua number. It reads your East or West group, your four supportive directions and your four cautious directions, with traditional placements for the bed, the desk, and the dining seat, plus a seven-day experiment. It is personalised to your direction profile, the eight directions that follow from your Kua, not to your floor plan. $19, one-time, no subscription. It is available now in the shop.

What about Western feng shui versus Classical feng shui?

Both are used by working practitioners. Classical schools use a compass and birth data. Western BTB uses the front door as the reference. We teach the Classical Compass School (which produces your Kua number) and we link both methods in the methodology page.

Feng shui is a structured design tradition. Key practical recommendations are labelled where their basis matters: design-supported, traditional feng shui, applied observation, or personal preference. We say so when the answer is uncertain, and we describe what a move supports, leaving the outcome to your own home.
