Wall material problem for interstitial space on vaulted ceiling - help?

[Madota]

Hi all, 

 

I'm a first timer, so be gentle

 

I am planning a side extension with a vaulted ceiling. See images: first from inside, second from outside.

 

Inside the side extension, I have set the exterior wall (from main house) as plasterboard for both the 1st and 2nd floor - the 2nd floor was trickier, but I managed it if you see the second floor picture above.

 

The problem can be seen in the first photo. The interstitial space (is that what it's called) shows external brickwork - not plasterboard. I tried using the material eyedropper, the result is plasterboard coloured brickwork.

 

Can anyone help? Do I need to make this scenario clearer?

 

Thanks

Share a copy of your plan here so others can look and then report what was found please.

Thanks so much Jo_Ann - that worked

 

However, I now have another problem that I have tried to work around - with no success. I have Brick material showing in the top corner of the ceiling. See attached image.

 

@DJP - thanks for your response, I have attached my plan this time round.
