Walking through a building model with camera tracking in Blender 2.8

This is a video about an old house (built about in 1910) in village Jászszentlászló, Hungary, which I have modelled in Blender and nowadays I'm 3D printing this.
Now I will present you, how I made an animated video of waking through its exteriors and interiors. The animation has made in Blender 2.8.
