This TARDIS is a marriage of quite a few designs. For starters, the main console room is based on the Hartnell interior with a custom spin on it taken from CommandrMoose's redesign of the Dalek Mod Beta interior. The console is placed in a depressed center of the room, while there is a set of stairs linking the upper and lower level. On the upper level, there is still plenty of room to walk around, even with all the decorations strewn about. Underneath the console, modeled blocks are used to add details of inner workings. Directly underneath is a secondary console room based on the War Doctor's TARDIS. In there, you will find a window to the time vortex made using an untempered skism. Connecting the two console rooms is a ladder in a separate room linked by corridors. The ladder room itself is quite bland, but I haven't decided how I want to improve it yet. Meanwhile there's room to expand with the closed corridor doors.
I can get more photos if you want to see more of the interior.
Here's some more photos I thought you'd want to see. If you look closely, you'll find I did some changes.
Redid the vortex window: placed the untempered skism behind glass instead.
