Initially, we are not aware of the Electrical / MEP Consultants and we have done our projects with an Electrician. DNR Sir was introduced through Architect Karthikeyan sir Dhyan Architects. Further, we have associated with DNR Sir through our Project KC Textiles at Thiruchendur. During our first association, we felt the charges are expensive about. But, the electrical systems are designed very comfortably and also energy-efficiently. So, we are enjoying every moment of every day of the service that has been provided by the DNR Team. Also, Lighting is very important for the textiles showrooms. And DNR sir has proved his service in the lighting design and Product suggestions in this project. We are more comfortable with his consultancy and service. So, we blindly believe DNR sir and team for our finished projects and upcoming projects.
60 years of the textile industry, third generation. We are the third generation to continue our grandfather's traditional wholesale business. Additionally, we established our business in the retail industry. Without any prior expertise in showroom electrical, lighting, or other interior knowledge, we made the decision to launch a new business a few years ago. Following a recommendation from our friends, we contacted Prashanth Pdsyns, he introduced his MEP team: Mr. Giritharan sir from Tropical Consultancy (Mechanical Team), Mr. D. Nagarajan from DNR Consultancy (Electrical Team), and Mr. Devaraj from D&D Consultancy (Plumbing / Fire Team). The MEP team has worked effectively together to efficiently finish our new project on schedule and in accordance with the precise design requirements. DNR Sir in particular paid close attention and offered some creative suggestions, both generally and in terms of work. Additionally, he provided guidance and discussed the job sequence to periodically finish the works. He wholeheartedly embraced our recommendation. Additionally, he evaluated recently released products and made recommendations for us. Although we were hesitant to follow his advice, we were ecstatic with the results. He gave us just what we expected. In the end, the interior and lighting design perfectly complemented Prashanth Sir's architectural vision. The fact that every floor showroom shot matched the architectural 3D plans exactly throughout made me really happy. Meanwhile, they provide end-to-end guidance on AC capacity and electrical voltage, which is well-planned, well-analyzed, and supported through to completion. Working with Prashanth Sir, DNR Sir and team makes us extremely satisfied. I also hope that Showroom endures for an extended duration and that we can collaborate on other projects in the future

Amazing team feel – we all pull together, and help each other when needed. Everyone is trusted to do their work… There’s a varied workload, allowing me to use skills I already have, whilst being exposed to things I’ve never done before.
