We are currently planning to build an EFH with 2 full floors. The walls are up to 6m high (ridge height up to 9m). We want a ceiling height of 2.7-3 m at the bottom and about 2-2.5 m more at the top.
We are still deciding whether to build with or without a ceiling on the top floor (open truss, gable roof 25*, so huge room heights are possible).
An open truss will probably cost about $15k-20k more, but in return you get spacious rooms, light through the skylights and can add a gallery later if necessary. With the ceiling, it's easier to install spotlights, it'll cost less, and you'll have the attic as extra storage space (because we don't have a basement, but we have lots of storage rooms/apartments, garages, garden sheds, etc.), although it'll probably end up just junk there anyway...
What do you think? Which makes more sense?
It looks without a ceiling more like a summer house than a house.
