The Twelve Astrological Houses: Meanings, Systems and Simple Reading

← Back to Guide to astrology basics

The houses divide the sky into twelve sectors starting from the eastern horizon. The meaning of each one, angular, succedent and cadent houses, systems (Placidus, whole sign), a simple way to read them and their limits.

Houses and signs: “where” and “how”

The signs divide the zodiac, a large fixed circle along which the heavenly bodies slowly move. The houses divide the sky as seen from the place and moment of birth, which is why they turn with the Earth: over 24 hours, every sign passes through all twelve houses. A way to remember this: the sign says “how” (the style), the house says “where” (the area of life), and the planet says “what” (the function). This formula is a teaching image used by modern astrologers.

The invention of the houses is linked to that of the ascendant, around the early Hellenistic period of astrology (roughly the 2nd to 1st century BCE, in Egypt). The Greeks spoke of “places”, what we now call houses.

The twelve houses, one by one

House	Traditional domain	Keywords
I	Self, appearance, beginning of life	Identity, body, first impressions
II	Resources	Possessions, income, personal worth
III	Immediate surroundings	Siblings, neighbours, studies, short journeys
IV	Roots	Home, family, origins, private life
V	Creation and pleasure	Play, love, children, hobbies
VI	Daily life	Everyday work, habits, obligations
VII	Others	Partnership, associates, contracts
VIII	Transformations	Crises, inheritances, what is shared at a deep level
IX	Horizons	Long journeys, higher education, beliefs
X	Public life	Vocation, reputation, achievement
XI	Community	Friends, shared projects, ideals
XII	Withdrawal	Solitude, trials, the unconscious

These meanings are fairly stable from one author to another, except for the 12th house, whose interpretation remains the most debated: some see trial and withdrawal in it, others inner freedom and transcendence. The 1st, 4th, 7th and 10th houses correspond to the four cardinal points of the chart: ascendant (eastern horizon), Imum Coeli (the lowest point), descendant (western horizon) and Midheaven (the highest point).

Angular, succedent, cadent

The houses fall into three groups of four, just as the signs fall into cardinal, fixed and mutable. The angular houses (I, IV, VII, X) sit at the four corners of the chart: they evoke action and what is visible. The succedent houses (II, V, VIII, XI) “follow” the angular ones and evoke consolidation. The cadent houses (III, VI, IX, XII) “fall away” from the angles and evoke learning. A planet in an angular house is traditionally said to be “strong”; in a cadent house, more discreet. This is a convention of the schools.

There is also a link with the elements: houses I, V and IX are called fire houses, II, VI and X earth, III, VII and XI air, IV, VIII and XII water. Each house then evokes, by analogy, the sign of the same rank (house I Aries, house II Taurus, and so on). This is sometimes called the “natural zodiac”.

House systems

How do you actually cut the sky into twelve parts? There are several methods, called house systems, which produce different divisions:

Whole sign: each house corresponds to one entire sign, starting with the ascendant's sign. This is the oldest system of the Hellenistic tradition, forgotten in the West around the 10th century, still used in India, and rediscovered in the West in the 1980s and 1990s.
Equal houses: twelve sectors of 30 degrees each, starting from the exact degree of the ascendant.
Porphyry: each of the four quarters of the sky between the angles is divided into three equal parts.
Placidus: a time-based system, named after the monk and astrologer Placidus de Titis (17th century); very widespread today, especially in France, but impossible to calculate beyond the polar circles (around 66 degrees of latitude).
Koch: a variant of the previous one, proposed by Walter Koch (1895–1970).
Regiomontanus and Campanus: older systems, based on geometric divisions of the sphere.

The choice of system sometimes changes the house in which a planet falls. Astrologers have no objective way of settling between these methods: it is a matter of taste, school and habit. Most software lets you choose.

Reading a house without being led astray

To read a chart, first look at where the planets are: a planet in the 10th house will be read as concerning public life, in the 4th house as concerning private life. Many houses are empty: this does not mean they don't matter. In that case, look at the planet that rules the sign on the house's cusp (its “ruler”), and at where that planet is: this is how an empty house takes on meaning. A chart with no planets in most of its houses is entirely ordinary.

A practical remark: the planets above the horizon (houses VII to XII) were visible at birth, those below (houses I to VI) were under the horizon. Astrologers see in this a turning toward the outside world or toward the inner self, though this has never been verified.

An honest view of what this reading can tell you

The houses are a classification tool for the areas of life, inherited from Antiquity. They depend on the time of birth: a few minutes' difference can change a planet's house. They also depend on the system chosen, which limits how solid any conclusion can be. No study has established that a planet's house predicts anything at all. See the history and limits of astrology.
