He has glowstones in there, that would require a nether trip

i'm a n00b, plus it would take me weeks to find that much wood and sheep where i spawned at.

supplies and build style

it would take me about 3 minecraft

Supplies?
Just cut down like 10 trees, and the house is super tiny.

Wool? stone? coal?

stone and coal? go mining?
look on any walls?
Wool, maybe, but if you find enough sheep, just slaughter them.

yes but if you want to cut wool effectivly you need shears , which you need iron for , plus coal to smelt it and a furnace that is constructed out of stone ,
plus food , to survive
and you cant come out at night
and you need to find sheep , which my minecraft refuses to spawn on a radius of 50 out of my spawn

its not about finding them , its about how much time it will take you to find the amout of coal needed

Well, you CAN use wood to make charcoal, and you can also just use wood to make the the ore into ingots.
and if you need shears, you need 2 pieces of iron, and you can smelt both of those with 1 measly piece of coal, or 4 logs.

yes but to mine iron you must have a stone pickaxe , which means you need to go mine the stone , go back home and construct it , considering the fact your not speed-playing

But, still, not even speed playing, plonk down a crafting table after you get your wood, make a wooden pick, mine stone which is literally 5 blocks below dirt, mine it 3 blocks, go back up, make a stone pick, go into a cave, find your 2 pieces of iron, 1 piece of coal and 8 pieces of stone, plonk down your crafting bench, get some wood, make a house, put down your smelter, smelt the iron, make shears, find sheep, done. If you actually try and look fer a cave, that can be done towards the beginning of night.

How should he go out in the night with no armor or effective weapons? he will be raped with creepers , plus you need to find shelter first , if you build it on the first day it will consume half of the day , making of the shears will take the next half , food finding does consume some time because you dont have an effective weapon, night is out of the equation because you have no protection .

the next day is finding wool , red flowers , materials, making a bed , and you have about 3 minutes left over
thats how my minecraft experience is like on the first day if i want to build a house like this

If making a shelter takes half a day, then you're trying too hard. First shelter should be nice and simple, maybe a 10x10 square house with some chests n' shit.
