Alright, where should I start.

First of all, "Easy Survival House". I'm not entirely sure this type of build is exactly "easy" to construct in Survival mode, hence this is somewhat misleading (don't quote me on that, just my opinion), as well as the fact you've made this in Creative mode. Might as well just call it a house you built in Creative.

Now onto the build critique.

For something you've labelled as simple, it is far from that in the final design. In fact, I'd go as far as to say it may prehaps be "over-detailed" (loosely used); by which I mean the overuse of the stair/slab/fence type blocks over full ones.

Palette choice is fine, just not my taste.

General structure, Ok, but seems more like a small tower rather than a "house" per se. Prehaps expansion from more than just your 7x7 square base into an amalgamated shape would be better.
