Cabinetry: Custom cabinets cost more than stock or semi-custom options.
Lighting Fixtures: High-end lighting fixtures can add significant costs compared to standard options.
Drywall: The thickness and type of drywall (e.g., moisture-resistant) can affect the price.

3.3 Complexity of Design

The complexity of your design plays a crucial role in determining the cost. Intricate designs with custom features, such as built-in entertainment centers, wet bars, or elaborate lighting systems, will require more skilled labor and specialized materials.

Custom Features: Built-in shelves, entertainment centers, or bars add to the cost.
Lighting Systems: Complex lighting designs with dimmers and accent lights can increase expenses.
