stayinwonderland Posted December 21, 2012 Share Posted December 21, 2012 I have a drawing where the base of the building shows a line that says 14.74FFL and the first floor level has a line that says 17.44FFL. I need to ascertain the floor height, so do I (and this is a wild guess) subtract 14.74 from 17.44, giving me the floor height in meters? In this case it's 2.7m? Does this sound right? Thanks.

Stephen Thomas Posted December 21, 2012 Share Posted December 21, 2012 Yes, that's right. FFL refers to finished floor level i.e. the level of timber flooring or carpet etc. Sometimes plans may refer to SFL or structural floor level which would be the level of a concrete slab for instance before floor finishings have been fitted.

stayinwonderland Posted December 21, 2012 Author Share Posted December 21, 2012 Cool, thanks for clearing that up. And my calculations are correct? Just wondering why a floor level is at such a seemingly arbitrary number as 14m? Link to comment Share on other sites More sharing options...
Stephen Thomas Posted December 21, 2012 Share Posted December 21, 2012 It will be in relation to an Ordnance Survey base level. Link to comment Share on other sites More sharing options...
salvador Posted December 21, 2012 Share Posted December 21, 2012 2.7 is quite an ordinary height for the regular house span. However, for a building, it's sounds a bit short. Yet, Stephen is right. Link to comment Share on other sites More sharing options...
