Do my siblings have a right to my money, which I earned through my work and with which I built my house, knowing that they inherited nothing from my father and did not contribute to building the house or supporting the family?

Your brothers have no right to take anything from your private property, for "The wealth of a Muslim is not lawful except with his willing consent." If there is a dispute over the ownership of the money, then the resolution is by referring to the Sharia court.
