The important thing to consider is price per square foot versus comparables. The exterior is never going to be beautiful, but you can improve it drastically for a few thousand bucks without ripping the whole facade off & starting over.

1) Paint the entire house, top and bottom, including the brick, a unifying color. Choose a color you like, keeping in mind the pale gray roof - so choose somthing compatible.

2) Nothing screams "bad addition" more than part of a house sitting on a former driverway! Rip out as much of the right side driveway as your lifestyle/parking needs will allow.

3) Landscaping can disguise/distract the eye from a multitude of architectural sins. Plant shrubs next to the house all across the front. Add a border of river rock or bricks to better delineate the driveway & walkway. PLant shrubs in front of the walkway across the front of the house if you use it. If not, rip it out & plant shrubs next to the house. Plant a tree to disguise the awkward space between the large window and the pygmy window.

4) Paint your front door an eye-catching contrasting color & paint screen door if you must keep it. Remove the screen door if you don't need it.

5) if budget allows, lay stonework over the path to the front door. slate would be lovely.

Good luck! Let us know how it turns out!
