The duplex design with modern style and strategy is ECO-FRIENDLY
From the street, the upper level setback inside so generally give the friendly feeling to guest and neighbors
All room have direct natural light, so it more safe electricity than other design which can not deliver all rooms have window.
My design is combined of two option with/ without master bedroom on first floor, client could choose one for their mirror if they think that one of two layout fit with them.
This is my fault to upload my design, all the plans and sections, elevations are hidden because I upload at the drawing with dimensions zone, so it can not be seen event with client, so every one seen these images only. I will post to my portfolio for further comments. Thank you all, guys.
