Inside the following spoilers, I have a number of shots for you.

All of my old worlds were deleted, so I started a new one. It's going pretty well atm, although I know I might not have the most impressive structures. Just take a look and tell me what you think.
This is the first house I built. The floor is pure dirt, it was only a semi-pretty hovel I used as a temporary home while gathering resources. After I was done with getting a lot of cobblestone, I began building my fortress.
The fortress is below. It has two levels, where the upper is practically only a living bedroom tower and some roof structures, and the lower is my small courtyard and workshop. Also, I was tired of creepers blowing up the walls every time I went out of the door, so I made the bridgelike structure around my castle as well as the moat. It's a pretty safe place.
This is my courtyard. Note that I have made small holes to look through. It's valuable by knowing whether it's day or night.
This is my bedroom. Not much to say here - I'm considering expanding it or something, possibly making all of the walls woollen and colored to prettify it.

It would, however, require a major rework on the main castle structure. It might just be easiest to build another fortress.
Here's the interesting part! First off, it's a panorama view of all of my buildings. Secondly, it's an outhouse I built solely for one reason... I captured four cute wolves! And of course they need somewhere nice to hang around!

So I made this outhouse, just for them.
Finally, this is the outhouse. I tried to make it feel natural and comfy, but it will of course never fully resemble their wild home in the forests. I hope they will feel at home, though, there was really put love and care into the building. I love my pups. Their names are Archimedes, Fetcher, Toffi and Damien. Take a look at their home.

You can see them hang out in there too.
