Plan your built-in project. Take measurements of the space the built-in will occupy. Browse magazines for examples of how the final built-in should look. For large projects, consider hiring a freelance interior designer to plan the project. According to the Bureau of Labor Statistics, the median income for an interior designer is $44,950 a year, or $23 an hour. Designers may also charge a percentage of the overall project. Be sure to include this in the cost of your built-in project.
Determine the cost of materials. This will vary widely based on the quality of wood, hardware and fixtures you choose. Add in the cost of upgrades such as environmentally friendly Forest Stewardship Council-certified hardwoods or formaldehyde-free substrates. You can save money by reclaiming old cabinetry materials, such as handles. Open shelving or mixing pre-built pieces in with custom work can also save you money.
Choose a carpenter or cabinetmaker. The Bureau of Labor Statistics reports that the median hourly wage of a carpenter is $18.72 and some craftsmen make up to $33.34 an hour. The cost of a carpenter will vary based on skill level and geographic location. Secure quotes from several before beginning your project.
