Specialty Angled Cabinet Help!!

Hi everyone,

I'm wondering if anyone knows how I can properly build this cabinet; its angled at the back 45 degrees, and has an angled front door. 
I've tried using transitional cabinets, and it seems not to work for angling the back, only the front. I also tried chamfering the cabinet but the the door doesn't angle..
See photo for the plan view of the cabinet I'm trying to build.

Thanks,
