A standard garage size is 3.5 metres by six metres, which is called a single âbayâ. For a basic budget, youâre looking at a standalone garage, rather than one connected to your home, which would require more extensive engineering, design and consents. Refresh Melbourne consultant Paul Cree says for a single garage your price range will be $30,000 to $40,000 which includes âbrick walls, metal roof, no internal linings for finishes, a manual door concrete slabâ.Regardless of the size, itâs important to consider what your garage will be used for.

Excavation And Site Prep

The average costs to excavate and prep the site for your attached garage is $3,500 to $5,700. This includes the land prep and demolition to open your home to the new structure. Like any build, the construction area must first be cleared and prepped. This varies depending on the condition of the lot beside your home.

Typically, excavation for a garage simply involves clearing the site of any landscaping and ensuring a level area for the foundation.

Building An Rv Garage Diy Vs Contractor

The amount of money that you pay for building costs can greatly influence the final price of your project.

However, you can also mitigate the cost of your build by either doing the work yourself with a DIY approach or paying a contractor to handle the development.

If you do not have a huge budget for the project, then the DIY option is going to be the way to go. You can focus solely on building costs alone and finalize your budget relatively quickly.

Roughly 50% of the total costs that you spend on building an RV garage are going to go to a contractor.

A contractor will charge you an average of $35 per square foot for the build, which can be several times the amount that you pay for your materials per square foot.

When you calculate this for the entire development the labor costs will add up to $14,000 to $35,000.

These are costs that you can completely avoid by taking the DIY approach for your RV garage.

With that being said, doing the work yourself requires you to be competent with tools and basic construction.

Although the DIY route is going to save you a lot of money, you do want to approach it carefully, as making mistakes and miscalculations in your build can result in time and money wasted.

If you are not feeling up to the job, relying on a contractor to build your RV garage is going to be a safer option given that you have a guarantee that the development will be conducted properly.

Detached Vs Attached Garages

Generally, a detached garage costs more than an attached garage. Because youre adding on to the existing structure, an attached garage only requires the construction of three walls instead of four.

A detached garage of the same size would likely cost more since its an entirely new construction project that involves more labor and materials.

The Cost Of Materials

Attached Vs Detached Garage Value

The materials you choose for your garage will have a large impact on the cost of the project. When considering the material costs for your garage, take each of these factors into account:

  • Doors: Garage doors are a specialty item that most contractors will hire subcontractors to take care of, which makes them one of the costlier parts of construction. Garage doors can cost between $500 and $900 before labor costs . Remember that if youre planning for a two-car garage, youll need to double that.
  • Siding: Once your garage is built, its time to finish the exterior. You can opt for a variety of materials, including vinyl siding, aluminum siding, cement board and wood. These materials range in cost from $2 per square foot for vinyl to $6 per square foot for cedar siding.
  • Foundation: Your garages foundation will depend on the local climate and your homes setting. If the ground doesnt freeze where you live, you can likely get by with a poured concrete slab. In climates where the ground does freeze, youll also need footers that reach below the frost line. Either way, estimate $2.50 to $4.50 per square foot, allowing for higher costs if excavation is needed.
