The question is, is this your forever home? If not, how long do you plan on staying? Are you planning to do something that simply cannot be undone? Are there CC&R’s in your neighborhood?
If this is your forever home, then throw away your concerns! Of course you can’t do anything that will compromise the structural integrity of your building, but other than that, the only opinion you should care about it yours! (and well, I suppose that person that likely shares the mortgage with you!) If you live in a neighborhood with CC&R’s then you will need to comply with those rules, but you can still get plenty creative and express yourself even within the confines of rules!
I told my husband I wanted a life size ballerina giraffe sculpture in our front yard, he looked at me like I was crazy, but again, it’s my house too and I really don’t care if the neighbors think it’s weird, it would make me happy!
However, if you only plan to live in this home for a short period of time you may want to think about keeping your bold choices to elements that can be easily changed out for a palette that is more monochromatic or art installations that you can take with you when you leave (that is, if the new owner doesn’t want them!). Go ahead and paint your house a rainbow with a leprechaun mural, but when it comes time to sell, maybe leave an option for home buyers to repaint, and on your dime…
But who knows, maybe the whole block will catch on to your kind of awesome!
