- Basic Finish: This tier typically ranges from $30 to $100 per square foot. It generally includes laminate or carpet flooring, drop ceilings, and paint-grade drywall.
- Standard Finish: Costs range from $50 to $130 per square foot. This level often features Luxury Vinyl Plank (LVP) or tile flooring, textured drywall ceilings, and upgraded lighting layouts.
- Premium Finish: This high-end tier starts at $75 and can exceed $150 per square foot. It includes luxury materials like engineered wood or natural stone, custom tray ceilings, and high-end features such as wet bars or custom wall panels.
