I blame Harry Potter

I'm developing some new work at the moment for 2 outdoor exhibitions. The plan is to create a series of (or maybe just one) cardboard tent/s. From the outside, the work would appear to be an unassuming temporary cardboard structure, the inside however will be filled with decoration, such as marquetry walls, dust carpets, a vaulted ceiling and pin prick patterns in the roof, . As I started making the work today, I realised there was quite a big flaw in my idea, one which defies physics and requires magic to pull it off. See when I imagine looking at the outside of the tent, I see a tiny old triangular tent hugging the ground, pulled taught with guy ropes. Its just big enough for one person to crawl inside and lie down. There is long wild grass partially camouflaging it and it's way off in the distance, small in comparison to the large expanse of sky and field. But, and here is where physics got left out of the plan, when I go inside I have been imaging it to be huge - bigger enough for 4-5 people to stand up in and walk around without bumping into each other. It was only today when I started my first attempt at building the structure that I realised I had been working with the magical scale of imagination.

So I have to put aside working out the actual scale of the piece, and let it simmer in my mind, while I tackle some other details, such as how do you make a tent out of cardboard boxes, how will it stand up, how will I make it weather proof...
