In an era when McMansions have become a norm, a few people are discovering the joys of downsizing their homes.

According to the New York Times, tiny, pre-fab homes are a growing trend, especially among eco-savvy homeowners.

The homes -- which are often used as second homes for many homeowners -- have several clear advantages. They are pre-built, and typically cost under $100,000. Some people are putting them on land that they own, while others see them as a good option if they want to visit nearby family for extended periods of time.

But, make no mistake: These homes are tiny. Many are well under 500 square feet, which makes them about the size of a tiny Manhattan studio apartment.

Having lived in a tiny New York apartment for many years, I can honestly say that living small has real charms.

Small spaces shave off maintenance costs and energy bills. You spend much less time cleaning. Now that we can store books, music and movies on a computer, we need less space for shelves and media storage. Best of all, a small space forces you to think carefully before buying anything, and that cuts down on a lot of unnecessary clutter.

So, I can see the advantages of a tiny home. In fact, it wouldn't surprise me if these homes start to outsell McMansions. Especially once people realize that they can save thousands of dollars on their energy bills alone.
