Initial Considerations
Planning and Design: Before diving into costs, consider what you want your transformed garage to be. Custom designs may require architectural plans, which can add to initial expenses. Hiring a designer or architect typically costs between $50 to $200 per hour, depending on their experience and location.

Construction and Remodeling Costs
Structural Changes: If your transformation involves structural changes, such as adding walls or windows, costs can escalate quickly. Basic remodeling projects might range from $10,000 to $30,000, while extensive renovations could exceed $50,000.

Flooring: Choosing the right flooring is crucial for both aesthetics and functionality. Options include:

Concrete: $1 to $3 per square foot

Ductless Mini-Split Systems: $2,000 to $5,000
Plumbing: If your transformation includes a bathroom or kitchenette, plumbing costs can add significantly to the budget. Basic plumbing work typically starts around $1,000 and can reach several thousand dollars, depending on the complexity.

Interior Finishing
Insulation and Drywall: Proper insulation is essential for comfort. Insulation costs can range from $0.50 to $2 per square foot. Drywall installation typically costs between $1.50 and $3 per square foot.

Painting: Fresh paint can enhance the look of your new space. Expect to spend $300 to $800 on paint and labor, depending on the size of the area and the quality of materials used.

Furnishings and Décor
Furniture: Depending on your intended use, furnishing the transformed garage can range from $500 to $5,000 or more. For example, a home office may require a desk and chair, while a gym may need exercise equipment.

Storage Solutions: Consider built-in shelves or cabinets, which can range from $1,000 to $5,000 based on materials and customization.

Contingency Costs
Unexpected Expenses: It’s wise to set aside 10% to 20% of your total budget for unexpected expenses. Older garages may have hidden issues, such as water damage or structural concerns, that need addressing.
