Survival films, maybe, like Castaway where whoever is stranded somewhere or a film where there holed up in one place due to whatever (I think there's a Dawn Of The Dead film where their hiding in a farmhouse)Humor, Horror, Drama, whateverThe Terminal or The Breakfast Club is all I can think of at this moment for an exampleThe plot doesn't necessarily have to be about survival, just where the movie mostly takes place in one area, I guessSurvival, they're trying to get out, or just anything really, as long as the plot is good (or not, just suggest whatever.)
12 Angry Men - the majority of the movie takes place inside a jury room Phone Booth - he was in the booth through the whole movie pretty much Panic Room - inside a house that was broken into Rear Window - inside one room in an apartment Das Boot - inside a submarine Devil - most of the scenes take place inside an elevator 127 Hours - he was trapped in rocks (true story) Flightplan - daughter missing on a plane Die Hard - he was trapped in the building Tremors - they were trapped in a small town by giant worm creatures Poseidon - they were trapped in a ship that overturned
Windows? Plastic film or new double pane, caulk Everything, expanding foam in crevices, new seal on garage door.
You need better circulation both inside and in the attic spaceAdd a ceiling fan in the office, and possible a power roof vent in the garageAny windows? If so, consider a UV film to block sun rays.
You could put up some 1 foam board.
