for a bigger renovation or update of the visual of your house, you would need much money.
In the attached pictures you can see, that i just made on all windows an little update. The update contain just a second row bricks over the windows in a nice shape.
In my opinion:
Just re-paint the porch' walls (if they are wood its verry easy and cheap) and the window frames.
This would refresh your house and keep the costs low.
Please for feedback.
