Exporting a Model from Blender into Unity? (Noob)

Hello! I’m new to the whole 3D game making process so please bear with me. Some friends and I thought it would be neat to make a small, FPS with just a couple maps to play around on. But we also want to add our own custom made models… I’m also brand new to blender, and after watching some tutorials, i made a small little house. I was wondering how i get that house into my map? I already dragged the .blend file into my assets folder, but its only has a white blank text document icon, which makes me think that its not recongizing it. If someone could just point me in the right direction that would be wonderful!

Thanks guys!!! Hope I can give back to the community once i get over the noob stage!

(if you want a screenshot of that icon just ask)
