Testimonials
Viz Kingdom work has become an essential part in Sameer Design consultants architectural work presentations. The quality of 3D renderings are high with reasonable prices. Viz Kingdom team quickly understands our architectural 3D comments and not only respond accordingly, but also add their inputs to come up with quality work within a short period of time. I highly recommend them.
Sameer Akbar, UAE
Professional service with excellent results. We used Viz to produce 3D architectural renderings for a development project. This was used in marketing materials and greatly assisted in our sales strategy. We have used them now for several projects and would recommend them strongly.
Binoy Karia, UK
I am a professional sculptor who creates monuments in outdoor public spaces. Therefore, I needed architectural 3D design renderings which depicted my sculptures within the future environmental settings where they will permanently reside. I was referred to Viz Kingdom via a mutual business associate, and I was not disappointed. They were very accommodating with all of my requests, even though I provided them with very short notice of my project. They took direction well, were very accessible (despite being overseas), and were also good at anticipating my design objectives. As an artist, it is important for me to collaborate with those who have ann ability to easily interpret my concepts, and this company seamlessly proved strong in that regard. I would definitely recommend their architectural visualization services to my fellow associates.
Alvin, New Jersey, USA
Kaushik and his team have served me and my clients very well over the years. Since we started working together several years ago Kaushik and his team have never failed to amaze me with their level of quality and attention to detail. Their work is amazing and highly effective for helping clients and contractors visualize our vision for various commercial and residential projects. It is without any reservations that I recommend Kaushik and his team to help you with professional renderings. 5 STARS!
Frank Cunha III, USA
My journey with Vizkingdom began with a simple search for 3D animation walkthrough services. However, it quickly evolved into a truly rewarding and collaborative experience. The team's genuine passion for architectural visualization was evident from the outset, and their enthusiasm was contagious. The final product exceeded my expectations and served as a powerful tool for effectively communicating my design intent to stakeholders and potential investors.

I can’t think of a better visualization than this. I would certainly recommend him for his expertise in 3d visualization eyes closed. Also would like to work with him in my future projects as well."
Abhilash Raveendran, Senior coordinator at Ceeyem, India
