The advantages are: 1  they are easy to dig in most areas. 2  they are easy to disguise after use. 3  they are private.  they disperse the waste rather than concentrate it (which enhances 1  decomposition). it is usually easy to select an out of the way location where you can be certain no one is going to casually encounter the cathole.
For the building of the garages, the typical costs will include: 1  Two car - According to Hanley Wood and their Remodeling magazine, the cost to construct a standard two-car garage addition is $58,432. This translates to $86 per square foot; and.
1 Concrete footings and slab to grade - The average price of concrete is $75 per cubic yard, with the full slab it that would require roughly 13 cubic yards for the two car version at a cost of $975, while it would take 27 cubic yards for the four car version at a cost of $2025;or this discussion we will assess the costs of building detached a two-car as well as a four car garage. The measurements of the average two car model is 26'x26'or 676 square feet. The average square footage of a four car garage is 48'x30' or 1440 square feet.
