how do I make a floor plan larger than 30' ?

[ivlaryann]

I'm new to this program and I'm using it to make a recreation of an existing house for work. The house is larger than the allowed area (30 feet) as I build the rooms I'm going to run out of space but I see where people have made buildings larger than 30' with sweet home 3D so what's the trick please? Im putting high priority on this thread because Im at work trying to do this right now and I kinda need to get on with this. thanks in advance for any help

As indicated in the help coming with the program:

The floor default size of a new home is 10 by 10 meters. If any wall, piece of furniture or room is placed out of this default surface, the plan pane will be automatically enlarged.
