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.

7636. 'In order that you may know that I am Jehovah' means in order that it may thereby be made known to them that the Lord is the only God. This is clear from the meaning of 'in order that you may know' as in order that it may be made known to them. The reason why 'I am Jehovah' means that the Lord is the only God is that Jehovah means He Is, that is, the Source of the Being and Coming-into-Being (Esse et Existere) of all things, which must necessarily be unique and one. For the fact that 'Jehovah' is the Lord, see 1347, 1736, 2921, 3023, 3035, 5663, 6703, 6905, 6945, 6956; and for the fact that the words used here mean that He is the only God, 7401, 7444, 7544, 7598.
