This question already has an answer here:

I built myself a decent sized house with a basement and it said it wasn't valid housing. So I built another one that is a very simple room with walls (dirt walls on the background, wood "walls") a door, two doors, a table, a chair, floors and light sources. I've gone over and over it and made sure there are dirt walls everywhere. It still says it's invalid housing.

I'm playing on Xbox 360.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Does it have a light source? – Fluttershy Mar 29 '13 at 18:55
Did you place all the dirt walls yourself? – SaintWacko Mar 29 '13 at 19:15
Yeah, I have a couple light sources. I did place the dirt walls myself. I guess I'll keep making it bigger... – Devil's Advocate Mar 29 '13 at 20:21
Does it have a table or workbench and a chair? Did you manage to create valid housing in the tutorial? – user45942 Mar 29 '13 at 20:41

I think your problem is this (based on you saying it has a basement):

If you dig into the ground at ALL and attempt to use the dirt wall as part of your wall, Terraria thinks it's not valid housing.

Take out that hammer and get rid of 100% dirt walls and replace it with whatever kind of wall you want.

This is probably what it was. My first house did have a basement, but the one I created afterwards that was just a simple square probably did have one row at the bottom of dirt wall that was already there. Thanks. – Devil's Advocate Mar 29 '13 at 20:51
Note, you can use dirt walls, but they have to be dirt walls you placed, the default dirt walls have to be removed, then replaced by your own walls, of whatever sort. – McKay Apr 1 '13 at 14:09

Terraria Wikia has a complete list of everything required to make something valid housing. Light source appears to be missing from your description in the question, I'd start there.

I forgot to mention it. I have two torches and a tiki torch... – Devil's Advocate Mar 29 '13 at 20:21
@Scott Then please correct your question. – SevenSidedDie Mar 29 '13 at 20:36
