How to build a custom closet

The cost to build a closet is between $17 and $30 per square foot. More customized projects (think, a Kim Kardashian-worthy walk-in) will cost more, while simple custom closets built into an existing space will cost less.

The cost to build a closet averages $2,001, with a typical range between $1,076 and $2,950. Prices depend primarily on size. Walk-ins are $750 to $3,500, compared to $250 to $1,500 for a reach-in. Solid wood doors and other high-end additions can run the most.
