I'm not sure if this is old news but I recently noticed this house which looks to have been griefed or destroyed by someone. Does anyone know what happened here and whether or not I should be worried about it happening to my base or builds as well?

It's very simple, I have a spot to get water on the left, a garbage disposal on the right, and some chests towards the front to store things in. Everything else is just decorative. On the Shelves Starting on the left I have a Potted Bamboo, then 3 candles (uncolored). Between the two shelves there are two lanterns hanging from the ceiling, on the next shelf there are 3 candles and finally a cherry blossom Bonsai (sapling in a planter). I used Polished Diorite to make the countertop and hid glowstone underneath it (also under the carpet).

Here's a View from the other direction:

I saw the Lapis blocks idea in someone else's build a while back (like back in classic minecraft 1.7.10 and thought it looked cool so I also did it here. I might swap them out for fish tanks later.

I put two decorative pots (also put glowstone under them) on either side next to the chests and put flower pots on top of them, not sure what I'll put in them but for now I have a wither rose in one of them (the one on the right in the picture).

I recently Finished building the Crafting area in my base which houses some Miscellaneous storage, the Crafting Tables, Some Regular and smelting Furnaces, item incinerator (what the Lava is for), and an enchanting station. I also created my own banner design which you can see in this picture.

Here are some Screenshots at different Angles showing off the room:

I've decided to do something rather unique as far as home bases go in Minecraft and have decided to build it in a roofed forest, using the tree roof and the trunks as the main structure.

The area you see going down is to my crafting area, forge, storage area, as well as a variety of indoor farms but it's still very WIP. Interestingly the only entrances will be up on the roof (I plan to build a portion on the top like a regular house but with leaves) and through the Nether portal, which will go in the underground portion but currently isn't built yet.

I found this little guy lost in the Nether, not really sure how he ended up in there but since I had some fish on me I tamed him and now I have a new friend.
