Cool, i had all these things instinctively right when buying my house.

Unfortunately out of the 6 people living here i have the biggest commute :(

I live in one of the best-lit houses i've ever been in. The neighbours who miss 2 windows compared to our house, but are otherwise exactly the same looks like a dark crypt. The colors you use and the way you place your furniture also plays a big role in lightness.
