Have you thought about iron fencing or a driveway entrance gate? Sometimes a great entrance to your property can really make heads turn!

Here is an example of a gate that compliments this house that looks a little similar to yours, definitely adding curb appeal.

Also a sample of simple iron fencing. Pillars are a nice touch, but that element might be too matchy matchy for you :)

I would like to paint trim around windows in light color the same as for roof triangle ( white or beige)

here is example with dark olive...but looks too dark for me
