Building a house by default, on a challenging block that no-one will build for me.
Also there is a whole lot of different nuances associated with building a house of this style. To begin with the layout is tricky. What rooms do you have upstairs and what do you have downstairs ?. Also its a bit more expensive - this was surprising but it turns out the little things such as better sound insulation between floors (generally upstairs contains people sleeping, mine will be people living which is noiser.... supposedly), theres also more plumbing, more electrical wiring etc that all add's up.
On the plus side, the handful of people that have seen my block all seem to agree that an upside down house makes sense however for the most part people just think I'm wrong.
So - dear readers of this blog (well hopefully "readers" - the little counter goes up but really not sure if it means people are reading or bots are just trawling) over the next couple of days I'll put up picture of my "views" and lets see if the verdict is that I'm nuts - or not nuts ;).
