Albert, you were asking about making a Sontaran costume and a Tardis. I can’t answer to the costume but I can give you some direction for a Tardis. I built a Tardis and turned it into a photo booth that I rent around the US. https://youtube.com/shorts/hkSP5kALM84?feature=share
For my inspiration I watched a man that built one and he shows it broken down in parts in a YouTube video, You can see it here: https://www.youtube.com/watch?v=ppTyzBscbHI
This really made it easier for me to picture when you see it broken down into parts.
