Made in blender. This is my first project.

Garage doors, walls, sign, doors, and window all seperate meshes.Each garage door has seperate meshes for an open / closed garage. The garage doors are made of seperate panels if you want to animate them.

The height map on the outside didn't work in Unity, so the outside wall might look like plain concrete instead of metal siding. The main color should show up.

I couldn't find a good model like this for free, so I made my own.You can use this model in any thing you want as long as you don't sell it.
