Is it permissible to work in a usurious bank and take out a loan from it to build a house, knowing that this is forbidden?

It is not permissible to work in interest-based (usurious) banks, as it constitutes cooperation in sin and transgression. The Prophet, peace and blessings be upon him, cursed the one who consumes usury, the one who feeds it, its scribe, and its two witnesses. If a person is compelled to work in it, then it is permissible for him to remain there until the necessity ceases. Furthermore, borrowing with interest is forbidden, and one must repent from it.
