I've recently refound my footing in Minecraft, and have been experimenting with different buildings. One thing I've enjoyed is asymmetrical environments that blend with the natural generation of land around it. I discovered this style by building a small survival house on hardcore, underground, and quickly hopped into creative to expand on my designs with the materials I needed for the house I wanted.

Features of this house: 
-Fully automated lighting (redstone based)
-Side yard
-Water feature
-Asymmetrical naturalistic designs

Side Note: If there are any of you who watch Achievement Hunter's Minecraft series, and saw Episode 152, "Flip that House", you'll notice the facade is based around the ideas posed by the build team.
