The properties are really well designed and look good in the landscaping which usually accompanies the build. The thing is the American owners usually have a gorgeous plot to put the tiny home on, this of course makes all the difference. Some of them are placing them on land owned by parents or siblings, farms etc. I would imagine it would be very difficult to get a gorgeous site for such a home here in the UK and if it was available it would be probably quite costly so you might as well be paying full rent or mortgage on a regular property.
All of this however does not stop me from being incredibly fascinated by how people manage to live in this way. I like all the space saving ideas and a lot are similar to the way we live when we go away in the caravan. That is just a week at a time though and I do like to sew and have space to myself. I would imagine living on top of each other can be incredibly difficult.
There is a blog I have followed for some time called Rowdy Kittens Tammy and her partner had a tiny home built and lived in it for three years full time also moving locations a number of times for work. You can see it on her blog, they have decided to winter in a rental house due to the cold and the pressures of small living. I really enjoy her blog and she has always been very honest about the reality of living in such a way.
One thing that strikes me is that US homes are generally so much larger than ours here in the UK yet they are the ones choosing to opt for these micro homes sometimes, this can only make it so much harder to do.
