I would break it up into various rooms, approximately 10 feet by 15 feet each, though a longer one with a long narrow (2 feet?) water feature against the wall and seating and plants in the center part would work. Plants on the wall, making it vertically green. A path leading from room to room should jog, so you cannot see straight through. Change the theme of rooms, large fancy pottery, an outdoor dining area, sunbathing area if possible.

softyjain, If the windows need to be replaced I recommend looking at fixed steel to maintain the narrow profile of the windows and small window lites. Using fixed instead of operating will be a cost savings if you don't need to open them. Another option for hanging from the ceiling is a decorative light or chandelier. That way you still have light into your ceiling at night. We offer Renaissance solid bronze windows that don't require any finish or finish maintenance. Architects designers love the rose bronze color, which closely matches copper gutters. http://www.houzz.com/projects/152134/Renaissance-Solid-Bronze-Windows---Doors-by-Progressive-Solutions You may also be interested in this ideabook- http://www.houzz.com/ideabooks/18543834/thumbs/Bronze--Copper---Steel-Window-Ideas

We've had great success by putting small fences around our flower and vegetable garden, and trained them that they don't go in them. We even have a small wire fence around the base of a tree with the bird feeder, and the squirrels sit in there eating away as they know the dogs won't go over the fence.

This is a most unusual and interesting structure. I would not have been sure it was a house from the picture. Pameladunson and I are in agreement that the strong visual difference between the rather utilitarian-looking "guard" at the roof and the more decorative fence/gate in front isn't visually pleasing. Both should be from the same architectural design family, although they need not be identical. The windows appear to have quite a bit of small architectural detail as best I can make out from the photo. The railing in front seems to have a scale that is better relative to those window details than does the "guard" at the roof, so I would probably opt for changing the roof "guard", not the railing in front. If do-able dollar-wise, It might be even better to remove both the roof "guard" and the railing/gate in front and design something new for these areas that is a good match with the most striking details elsewhere on the house.
