Copper Beech next to house extension - viable??

[LalaBarr]

Hi everyone, we are about to plan a house extension in line with the existing ground floor (see pic) with the new roof height about the height of the gutter, flat roof, but would go further back and cut into the copper beech territory more. 
Wondering how we can save the tree as it would probably need pruning to not overhang the gutters and be so close to the house wall. 
Question:

will it even be viable longer term (10+ years), will it look a bit cut in half?
Or will the canopy eventually just spread over the roof? 
We do really love it but don’t want to plan the house around it, just to lose it in a few years or have a super butchered tree   It’s already been a bit chopped by previous owners. 

Thanks in advance!
