A house or flat number reduces, the same way a birth date does, to a single number from 1 to 9 — and that number answers to a planet. The planet's nature is the tone the home tends to carry: a warm, family-minded six; a quiet, private seven; a busy, restless five. It is not the whole story of a home — the people in it matter far more — but it is a real and useful leaning to know.
Find your home's number
Enter your house or flat number below — just the number, or with its letter (like 12B or 3A). You will get the single number it reduces to, the planet behind it, and the tone that number lends a home.
If you live on a street with a name and no clear number, use the number on your own door — a flat or house number — since that is the space you actually live in. When a building and a flat both have numbers, the flat number is the closer one to your daily life.
What each home number leans toward
Every home number carries the nature of its planet. None is simply good or bad — each suits a different life. Read these as leanings, not labels.
- 1The independent homeSun · For self-starters and leaders — a place to stand on your own feet and begin things. Can feel solitary, so reach outward for company.
- 2The gentle homeMoon · Nurturing and peaceful, made for couples, families and rest. Sensitive to the moods of the people in it, so it rewards calm.
- 3The sociable homeJupiter · Cheerful and expansive, full of conversation, creativity and guests. Can scatter focus and loosen the purse strings.
- 4The orderly homeRahu · Structured and hard-working, good for routines and getting things done. Can feel all-work, so build in room to rest.
- 5The lively homeMercury · Movement, change and comings and goings; it suits busy lives, travellers and communicators. Rarely a place of deep quiet.
- 6The warm homeVenus · The classic happy home — beauty, love, family and welcome. A natural nest, harmonious and easy to live in.
- 7The quiet homeKetu · Private and introspective, good for study, retreat and inner life. Can feel isolating, so bring the company in.
- 8The ambitious homeSaturn · Serious and disciplined, oriented to work and long building. Rewards effort, and wants some lightness added.
- 9The energetic homeMars · Active, generous and warm-hearted, often busy with people and causes. Can run hot, so it likes an outlet.
How the number is worked out
The method is the same reduction used everywhere in numerology. Add the digits of the number together; if the address carries a letter, add its Chaldean letter value too; then keep adding until a single figure remains.
- Flat 27 → 2 + 7 = 9. A nine home — Mars.
- 12B → 1 + 2 + 2 (the value of B) = 5. A five home — Mercury.
- House 148 → 1 + 4 + 8 = 13 → 1 + 3 = 4. A four home — Rahu.
For a home number we reduce all the way to a single figure from 1 to 9, because it is the planet's basic nature we are reading, not the finer shades a birth date carries.
The honest part
A home number is a tone, not a fate. The people who live in a home shape it far more than its number ever could, and a happy life is built in every kind of home. What the number does is describe the grain of the place — the things that come a little easier there, and the things you will want to make room for. A quiet seven home asks you to bring the company in; a busy five home asks you to build in some calm. Knowing the leaning simply lets you live with it, rather than against it.
What to remember
Add the digits of your house or flat number, with any letter's value, and reduce to a single number from 1 to 9. That number answers to a planet, and the planet's nature is the tone the home leans toward — warm, quiet, busy, orderly. Read it as a leaning you can work with, never a verdict on the life you build inside.
Common questions
How do you calculate a house number?
Add the digits together — and any letter's Chaldean value — and keep reducing until you reach a single number from 1 to 9. That is the home number.
What if my address has a letter, like 12B?
The letter carries a value, so you add it. 12B is 1 + 2 + 2 (the value of B) = 5, a five home.
Which house number is luckiest?
None is simply lucky. Each leans a way — six is warm, seven is quiet — and the right one depends on the life you want to live there.
Does the number really affect my life?
Treat it as a tone, not a fate. The people in a home shape it far more; a suited number just makes some things feel a little easier.
Reading a home properly
A Cosmiclogy reading can weigh a home's number against the people who live in it — in plain language, as a leaning to work with, never a verdict.
