Prefabricated garage kits come in a variety of sizes, designs and materials; but are typically made from concrete, timber or metal – or combinations of those materials. Prefabricated garage kits are most commonly used for garaging a single auto in; however, it is possible to purchase double and even triple prefabricated garage kits.
Footing and Bases for a Prefabricated Garage
Any construction requires a solid foundation or footing and the same is true for a prefabricated garage kit. Depending on the exact construction method for your prefabricated garage it might be possible to leave the base of the inside of the garage as earth, or just spread some aggregate over the earth or, better still, lay natural or man-made slabs.
However, even if a concrete foundation isn’t absolutely required for the construction, having a solid concrete platform for the inside base is to be recommended. That way, dependant on the internal size of the garage, should you decide to do any auto repairs in the garage you’ll have a solid base to use a lift on.
Whether you only need to concrete in posts to support the prefabricated garage or even if a concrete footing is required – then make sure you dig the channels to the required depth and use the correct concrete footing mixture.
Finally, don’t forget to make the concrete base higher than the actual ground level, in order to reduce the risk of surface water running into your garage, a rise of 4 inches is recommended, so you’ll need to form a small ramp in the concrete at the garage entrance.
Metal Timber or Concrete
You might be restricted in your choice of materials due to local building regulations or space. However, personally I’d avoid having a metal garage, especially if you live in a hot climate. Not only will the garage building get hot – but also getting into your auto in the garage will feel like you’re stepping into an oven.
If you’re living in a rural location, a timber prefabricated garage might look just the thing, but if you live in a particularly damp/wet climate then you will need to regularly treat the timbers. Also, unless properly treated, timber garages can present a fire risk if you want to store fuel and lubricants in them.
For me the ideal choice of material for a prefabricated garage is concrete. That’s not to say that a concrete prefabricated garage has to look like four slabs of concrete with a door and roof.
Concrete Prefabricated Garage Kits
A concrete prefabricated garage kit will basically be one of two types. It will either be panels that slot in between upright posts or panels that are bolted or screwed on to posts, with the roof also being mainly supported by the posts. Either way the integrity of the garage depends on you fixing the posts into the ground properly, so do follow the manufacturer’s guidance on this very carefully.
A budget concrete prefabricated garage may well just be concrete slabs with a wooden door and felt shingles for its roof. However, the better concrete prefabricated garages will allow you to add windows, automatic metal doors and apex tiled roofs.
However, it is in the panels you can use with a more expensive concrete prefabricated garage that really make the difference. Instead of just using plain concrete panels you’ll be able to buy faux stone panels looking like layers of bricks and other building stones; giving the impression of being anything but a prefabricated garage kit.
