Amit Mahajan is a Founder and Chief Architect of ONE DESIGN- a full service Architectural Firm along with supported auxiliary services such as structural + MEP consultants to oversee and finish the job. I have a broad experience in Residential, Commercial & Retail Interiors and Landscape Design and Architecture, amounting to over a period of 10 years.

After my post graduation in Master of Architecture (Urban Design) from United Kingdom, I was indeed fortunate to work with eminent international architectural firms - Benoy (UK) and Jefferson Shread Architects (UK).

ONE DESIGN has been running a practice which primarily focus on creating authentic architecture and interior design proposals which speak in volumes of its efficient design outlook.

ONE DESIGN has a team of international architects and designers working in cohesion to create satisfactory design with an influx of new architectural dynamics and technology. ONE DESIGN believes in a strong responsibility to contribute to our planet's social, economic and environmental sustainability in providing future generations with better environmental stability and potential than what exists today.
