@vikrant: thank you for the suggestions. i will definitely use them. @Dytecture: thanks a lot for this idea. this would work for ground floor living room but not for first floor's. Actually the wall is 14*20ft. Living rooms on ground and first floor share this same wall. we have kept some space open on first floor. Books will not be accessible from first floor. this is very close to my concept. this yellow wall is the common wall am talking about. but the space between this wall and first floor is not more than 4ft.

Please post this again in the Design Dilemmas section. More people will see it there. Very few people visit the Other section on Houzz, which is why it took so long for you to receive a reply.

After spending several years abroad I can share my observations. Most homes with snow fall use spanish or a slight curve. This is in an area that has: high winds, 2-4 ft snow intermittent years, and rain every third day. For snow and ice, some (but not many) have custom log braces about 4 foot from the gutter line. To be honest, falling snow and ice is part of living in colder climates. I would ask this company to get you in touch with their clients who own "the system" they are advocating. This way, you'll know what to expect from the product. If the shields help melt snow and ice, perhaps this is a good thing. All I would add to that is your offload gutter system and spouts are placed properly to avoid splashing against the home. I'll post a link if I find one that shows you what I am talking about in Europe.

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!
