Dear Mr. M.P. Shashidhar,
In Southern parts of India people install a small statue of lord Ganesha in a cubicle style temple. The temple could be placed on wall shelves on compound wall. The temple should not be covered with glass.
There are lot more other solutions depending on plot size and direction. You may hire a full time vastu consultant, who can visit the site and guide you accordingly.
