Cost Breakdown To Expand Garage
Garage Expansion Design And Preparation Costs
Designing and preparing for your garage extension involves several steps, including obtaining permits, drafting designs, and planning the project. These preparatory tasks can add significant costs to the overall project, generally ranging from 10% to 15% of the total construction cost.
Garage Extension Building Costs
The actual construction of the garage extension is the most significant part of the cost. This includes material expenses, labor charges, and costs of any additional installations such as electrical systems or HVAC units. Building costs vary depending on the size and complexity of the project, but they usually fall within the range of $60 to $120 per square foot.
Garage Expansion Remodeling Costs
Remodeling an existing garage as part of the extension project can also add to the costs. These expenses typically cover flooring, wiring, lighting, and adding any other features needed to integrate the old space with the new extension. Remodeling costs can vary considerably based on the scope of the redesign but are essential for a seamless transition between the existing and new areas.
Garage Extension Vs. Bump Out Cost
Extending a garage is often compared to a bump-out, a smaller addition that expands space without a full construction project. Bump-outs are generally less expensive, costing between $80 and $200 per square foot. Deciding between a full garage extension and a bump-out will depend on your specific needs and budget.
Cost To Tear Down And Rebuild A Garage
In some cases, it might be more efficient to tear down the existing structure and build a new garage. This option can be costlier, averaging between $50 to $70 per square foot for demolition and $60 to $120 per square foot for new construction.
Cost To Build An Extension Over Garage
Building an additional room or extension above your existing garage is another option, but it is generally more expensive than extending the ground level. Expect to pay between $60,000 and $200,000 or more, depending on the size and complexity of the new structure.
Is It Worth Extending A Garage?
Extending your garage can significantly improve your home’s functionality and value. However, it’s crucial to weigh the benefits and drawbacks:
Garage Extension Pros And Cons
| Pros | Cons |
|---|---|
| Extra space (ideal for small home or large vehicles) | Prohibitive cost |
| Guaranteed reserved parking | Lengthy design and construction process; often requires temporary relocation |
| Vehicle protection (weather, theft) | Reduced yard size when extending out |
| May lower car insurance premiums due to reduced risk | May require the entire structure to be brought up to code |
Getting Estimates From Garage Builders
When planning a garage extension, obtaining multiple estimates from reputable builders is crucial. This helps ensure you get a competitive price and a realistic understanding of the project scope.
Questions To Ask
To make the best decision, ask potential builders the following questions:
- Can you provide references from previous garage extension projects?
- What is your estimated timeline for the project?
- Do you offer a detailed breakdown of costs, including materials and labor?
- Are you licensed and insured?
- Do you handle permit acquisition, or is that my responsibility?
By taking these steps, you can ensure your garage extension project runs smoothly and stays within your budget.
