A "house" is essentially a container -- for a person, a family, several families or even a large group with shared interests (think of the term "houses of worship.") In the Bible, a "house" is also a container, but for spiritual things rather than natural things. In various uses a "house" can represent part of the mind, the whole mind, a whole person or even a church. The other nuance to the word "house" is that it is generally used in regards to our affections and desires rather than our thoughts and principles. This makes sense; we tend to engage our thoughts and rationality when we are out in the world doing our work, but when we are inside our houses we are driven most by love for our families and the desire to be good to those we love. So "house" tends to represent the things we want and care about -- which are ultimately the things that define us.

1260. Since 'nations' in the Most Ancient Church and in the Ancient Church meant goods or good persons, therefore also in the contrary sense they mean evils or evil persons Similarly with 'peoples'; since these meant truths, therefore also in the contrary sense they mean falsities. For in a corrupted Church good is turned into evil, and truth into falsity, as a consequence of which the meaning of nations and peoples in that contrary sense occurs many times in the Word, as in Isaiah 13:4; 14:6; 18:2, 7; 30:28; 34:1-2; Ezekiel 20:13; and in many other places.
