Cover the support poles with pole-wrap covers. The covers easily fit around the poles, and you should be able to install them without the help of a professional. Use wooden pole covers or paint them to match the walls.
Enclose the poles with post column covers. Place the two halves on either side of the pole and snap them together. Smooth a thin line of building adhesive down the line. Caulk any openings and paint the covers to match your walls.
Build a custom square or rectangular column around the post. Add decorative molding for a formal look.
Box the poles in your choice of enclosure and build custom seating around the enclosure. Cover the seats with cushions.
Enclose the poles and build a custom shelving unit or bookcase that runs between two poles or from one pole to the wall.
