Welcome! I could give you a few tips!
I've been playing mine-craft for about... 2 years, I've got alot of experience.
To light up a big area, use fences glass or open air, Its best to make the windows even and on each side of your house.
Its not good to use the same type of block for the whole house. Try using two of your favorite blocks like, stone bricks and wood.
You can make the roof flat, but try propping it up with slabs or stairs.
Try looking at pictures of Chinese houses or look at big statues such as the statue of liberty, Or a football field.
Each "tip" given here is a matter of personal preference. You do not have to accept or abide by these "tips". Make your roofs flat if that's what you prefer. Make you walls out of a single material if you want to...
