"Residence" sounds right. "Estate" sounds big to me = big house + lots of acres of land + big wrought iron fences. But why use surname. I seen plaques on peoples houses that read "The smiths"

A good beginning would be to replace the walkway up to the house. A new brick walkway or stamped concrete in the same color as the brick on the house will pull all of the elements of the exterior of your home together. I made my walkway 3 feet wide with 2 feet beds on each side of the walkway in stamped concrete. Create the walkway at a distance from the house in an organic natural flowing pattern up to the house with planting beds flowing beside the walkway. Take the brick right up to the from door. Soften the entrance to your home by opening the planting beds up by the house into large organic shapes. That's what I did with my home and it changed it dramatically! It's a lot of work but what a difference!

That's what architects and contractors are for. Hire one.

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!
