New to Unreal Engine 5.4.2 - Making architectural houses for game project

Hi there, I’m new to Unreal Engine and is just getting through the basics of it but I’m still trying to get the hang of it. I’m trying to start on the design of the architectural houses for my game project and only got the base of the house done. But I don’t know how to add furniture, textures, etc on the houses. If any experts who can show me the basics on how to make a decent architectural house in Unreal Engine, will be very much appreciated.

Maybe just get a free or cheaper project from the marketplace and see how they have done it.

In Unreal most people or game project use a library of assets (furniture, etc.) and assemble the scene with those assets in the Editor. You can get free high-quality assets from Quixel or Twin Motion to get started.
