360VR Tour: http://www.normdesignhaus.com/
No doubt the best way of architecture visualization would be the interactive VR created in Unreal Engine or any other similar software. But it will be too costly and time consuming. Spending a fortune just for 3D visualization is not wise if you're on a tight budget. Put the money on the building material, not on the drawings!
Why not view interior design the modern way with the immersive 360 virtual reality (VR) Tour. A more simpler and faster solution to 3D visualization. After all, it is the design that matters, not the technology.
