This particular client came to me as she was re-doing her apartment to make sure she was spending her money wisely and to make sure whatever she did, it was done right the first time.
She was originally thinking of using Elfa but I knew we could do it better and for a lot less money. I priced out Elfa vs a mix of hardware store options and Ikea. The Elfa came out to about $835, while the Ikea option came to about $210 (price not including tax, shipping, installation). The center unit (19 5/8"W x 22 7/8"D x 79 1/8"H) with it's 4 interior drawers, 2 shelves, and pull-out valet hook was about $140. Another pack of shelves and a closet rod that were all cut to fit around the center unit cost about $70.
