I am trying to get a small section of my PCB design to be ground-free as this is the advised layout given by the manufacturer of the component. 

However, I believe that because there are components within this restrict area that are, or need to be, connected to GND, the restricted area fills with a ground plane that I do not want. Below are some related images.

The red line indicates my desired restrict area. Ideally I would like this area to be free from the surrounding ground plane and I will route the components that are required to be connected to ground manually with a few tracks.

Alas this does not happen and below is the actual result I get once I have 'ratsnested' the design.

As you can see, the area has indeed filled in with the ground plane, although it is a separate one to the main one, it is still an issue. So I would like it not to fill in at all!

**Is it possible to do this on Eagle?** 

I need it because it is what the [manufacturer recommends](http://www.ti.com/product/BQ25570/datasheet/layout) for the layout and it has proved problematic already without following there guidelines so I would like to rule out any possibility for problems in the future.
