Prefabricated structures (prefab) are sustainable because they limit any material waste, can be assembled in a significantly shorter period of time, and can often be disassembled and moved if necessary.  I have elaborated on each of these points and more in a recent post about steel prefab.   However, I thought it would be a good idea to introduce prefab in the renovations blog. 

The reason being is that many new prefab start ups are designing and building sheds to go in back yards that serve as extra rooms for a home.  Popularly used as offices and work spaces, these structures range from 100 to 1200 square feet and can also serve as guest rooms and playrooms. 

Two companies worthy of mentioning are Modern Cabana and Modern Sheds.  Both start ups are products of the west coast and specialize in energy efficient prefab design that focuses on environmentally friendly products.   Modern Cabana prices start around 85 dollars/ sq. ft., while Modern Shed pricing is generally 100 dollars/sq. ft.
