One of the first issues is the orientation of the house. Solar panels do better on the south side. You should research whether your roof needs to support more weight. You will also do well to consider all aspects of solar building --- you can find books available in e-format for this. Go to Amazon and read reviews carefully. Things like roof overhang, kinds of windows, etc, can make a big difference in cooling your house (I'm assuming in India, heating isn't a big issue). For the solar panels, what's available where you are is a starting point. I will note that in sunny countries, like Turkey and Tunisia, I see a lot of solar hot water on roofs, but not so many solar panels.

Thanks Emmeline & Najeebah for your replies. Its a beautiful cinnamon tree. Najeebah, its a well growing tree..I would like to retain it at the current spot and have the living room adjoining it. According to the house plan, there would be only 4'depth from the wall to the main house. N since we live in a tropical region, i would not want the tree to be fully indoor. Mosquitoes & other small insects could find their way into the living area during the monsoon season. How can i show its beauty?Pls advise

Thanks a lot for your valuable suggestions and comments Rusty Empire,decoenthusiaste,emmarene & Chikka BangBang. My home is located in a small village in India. We initially planned to renovate our old home. But during the middle of renovation work, we changed our mindset to build a new one. Hence we made a house design by ourselves(3BHK) with the help of our local builder and to save the cost we tried to reuse all possible materials that were extracted while demolishing our old home((i.e.., like red tiles placed on the top of left side of porch). The project is in last phase, now I feel that still we could do something to enhance the beauty of exterior of home by getting some ideas from experts. I like to thank everyone once again for sharing your thoughts! @Rusty Empire : The entire building shown in pic is a single building, because of our inexperienced design it looks like disjointed:(:(. We just finished the painting of primer coating, yet to paint the final color. The pic you posted with color looks awesome, planning to paint the same color. I believe it would change the entire view of building @decoenthusiaste : The entire building shown in pic is a single building. Will post more pics in coming days, pls review it and share your thoughts. @emmarene : Right now I'm at my work place, so I don't have a main entrance pic with me. Will post it by this weekend. Please review it and share your valuable thoughts. @Chikka BangBang: That's gr8 idea, will think abt it. Thanks!
