As pointed out in the answer of the How do I build a house for my NPCs?

Fill in the house with background walls. Any player-placed wall will work.

The Snow background walls are not player placed, you need to replace them with something of your own.

Why does Terraria keep saying not valid housing?

"This is not valid housing." The room does not meet one or more of the following requirements: Walls, Minimum Size, Background Walls, Corruption Limit. If the corruption is at fault, usually it is only a small amount and it may be too far away to be seen on the same screen as the room.

What is considered valid housing in Terraria?

How do you uncorrupt a house in Terraria?

Simple put: Once too many corrupted blocks (Ebonstone, Corrupt Grass etc.) are near the housing, the house will become corrupted and invalid for an NPC. Simply purify the area or build a house away from the corrupted area while it suits the other requirement for it to become suitable.

How long do Terraria houses have to be?

Terraria is different in that there are rules to follow. Houses must be at least 60 tiles in size, but no more than 750. This includes the walls you've built around the edges. Walls must be made of blocks, doors, platforms or tall gates.
