3D Architectural Animation: Duplex Residential Animation

We've created this 3D Architectural Animation of a houses residential complex that is situated in Iasi, Romania. One main requirement of the client was to make a livable context in the video animation, so the potential clients could see it and feel it like they allready live in the houses they virtually see. That is why we've integrated a lot of human interaction into it, giving the houses trough that a high standard of living. In the absence of the physical buildings, the client needed the animation so they could sell faster and better. That is why we started the project right from the design stage. How else could that be better represented than trough a 3D Architectural Animation?
