Expand the front entry and create a more distinct porch. Whether you have a classic split-level or a split-entry, one of the most common complaints among split-level owners is the awkward front entry. If you don't want to expand the entry itself, add a more accentuated approach. This will make the home more inviting. Balconies and covered porches will also break up the boxy design often found in split-level homes.
Add windows. Split-level homes typically don't have windows on the sides of the house, and if they do, they are small. Adding windows will bring much-needed natural light to an otherwise dark and confined floor plan. Remember that windows change the inside and the outside of a house. Consult with a window designer or an architect to make sure your window choice and placement will add curb appeal.
Open the floor plan. Adjoin the kitchen, formal living room and dining room to create a more open design than the traditional split-entry home. People live a much more casual lifestyle then they did back when traditional split-level homes were popular. For example, today people gather in the kitchen --it is a place to entertain guests. Fifty years ago, the kitchen was rarely, if ever, seen by a guest.
Create a master suite. Remove the wall between two bedrooms to create a master suite. Split-level homes often have small adjacent bedrooms and a small bathroom close by. This could be a perfect setup to easily create a master suite.
