How to improve a rectangular boxy house.?

after the korean war..these boxy little ranches were built...no style...no nothing. i now live with my mother to help her and hate to even look at the house..it has aluminum siding and the front is landscaped near the house with shrubs..my Father before he died cut down two large maple trees that added a little character...i would like a frontal house change that is not astronomical in price..any ideas.i did the door and have large stone pots at the entrance with a seasonal flower. help!
