In my building on the ground floor there are certain areas that are four steps lower than others. Giving a difference in FFL of around 0.5m.
How would I create a different floor level within the same floor?
Hi Kieran, It is quite difficult to model stepped levels on the same floor, but you can instead model this by simply treating both areas as having the same floor level, and then adjusting the Room Heights to take account for the change in room volumes.

Further to my colleagues earlier reply;
If you do find it necessary to extend a room upwards due to floor stepping, you may find it intrudes into the floor above in 3D view. This is purely and solely a visual artefact of the 3D view and will have no effect on the calculations.
Once you have manually adjusted a room, when you set up Intermediate floors (in floors/roofs) you should exclude the room (using the exclude rooms list, highlighted below) to avoid forcing the room height back to the current floor height.
You simply need to go into the Room Data menu for the room you want to change (in CAD Input, double click inside the room), and the Room Height setting is in the top left corner. Change this to the height required, then click the green tick.
