Hi there, Have you tried searching the photos on Houzz for inspiration? https://www.houzz.com/photos/duplex-exterior-ideas-phbr1-bp~t_736~a_1410-15775

It’s a good idea to construct a duplex house with modern designs on a small plot of land. Ashwin Architects are one of the top architects in Bangalore catering to contemporary house designs since 2003. You can get their address and details on – http://www.ashwinarchitects.com/blog/contemporary-house-plans-india

Ground and first floor duplex will provide you great look and useable area. We personally believe in keeping the second floor separate for privacy and better space accommodation on the terrace floor
