<human>: So I work with my dad, he's a very experienced builder, and he currently is building an estate of around about 10 houses. 

Over the past two months we build it with a large timber frame that he had specially made to make the shell of the house. Free with the timber frame was a garage door. So we put the garage door inside the house to keep it from getting damaged by water and things happening on site.

So today we finished installing all the doors and windows. The bricklayer had also finished. We didn't really need to go into the house much as we wanted to finish the exterior while we had nice weather.

Today I opened the house to see that a garage door was still sitting in the kitchen. My first thought "Shit, how are we gonna get this out, its like 15ft long. The door is only just below 7ft...."
I told my dad, he looked at me with absolute horror, then burst out laughing. There is literally no way to get this garage door out of the house.

Can you condense the text into three sentences or less?
<bot>: Put garage door in house for safe keeping before the timber frame went up. Forgot about it. Finished house. Got stuck.
