Texture Issues

The last week I was working on my project I encountered issues with my textures, I had spent a whole day (9am to about 10pm) give or take an hour or two adding textures. Everything onscreen looked fine until I changed the preview mode to texture mode instead of solid. It was at this point that I realised I wasn't adding the textures properly. At this point I don't know what I was doing wrong. All I know is I was until 1am trying to correct everything and add textures where I could.

Above show the screenshot when I was in solid mode. Apart from the individual artist pods texture, everything here appears as I wanted it to. Wood panels on the walls, correct wood used in the kitchen tables and chairs and the correct textures of tiling used in the bathroom.

This screenshot in texture mode however shows the truth to my textures, the artists pods in this view are correct, so I was never worried about how they looked in solid mode but everything else had not appeared properly. I don't quite know what went wrong but if I don't have time to correct it all before assessment then I shall simplify it and add colours like I have done on the artist pods.
