Timber frames

[malcolm22]

I have an 8 week old timber frame house, and noted a difference in floor level (just a few millimetres) in one of the rooms. The joiner has told me that it can be corrected but I'd have to clear the room, lift carpets, etc.
He said it was to do with a 'floor capsule' and that it wasn't serious. Do I take his word for this, or get it put right?
Any advice welcomed!

Floor capsule? He may mean floor cassette. Has steel been used in the building structure? If the floors on one side are supported on steel which in turn is supported on the foundations, for example, and the other side is supported on timber, there will be a differential movement issue. Timber shrinks by approximately 1mm for every 38mm of horizontal timber, steel doesn't shrink (obviously). This may account for the level difference.
I doubt it is a structural problem but more of an aesthetic one if your house is just a 2 storey build. It becomes an issue with multi storey flats where more horizontal timber is used therefore more differential movement occurs at the higher levels.
