In Genesis 26, the well signifies that people who were in the mere worldly knowledge of truths of faith were unwilling to make the internal nature of the Divine more well-known. (Arcana Coelestia 3412)

Broken cisterns in Jeremiah 2:13 signify false doctrines.

In Deuteronomy 6:11, cisterns hewn out signify the interiors of the natural mind–full of knowledge of good and truth. (Apocalypse Explained 617[13])

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.
