You are most likely using the primitive cube to make your “house”.
Real developers use 3d model creation programs like Blender to make their models. In such models, there are things called UV maps, which tell unity how to render the textures on the surfaces.

There is no better and no other way.

Hope you learn how to use Unity, Benproductions1
