if the grillwork is for security--leave them! They are very expensive and these look like they are very secure. Painting it a dark color and/or painting the home, add some trailing potted colorful plants to stream down at the posts, some planter boxes or climbing bouganvilla or roses in flashy colors in the ground out front, and it would be comfy looking and beautiful.

the iron gate w bouganvilla pic didn't load..oh well.
