Can you purchase a (Bulk Head) packaged unit???

Can you purchase a (Bulk Head) packaged unit???

My step family have a large kitchen with alot of heat loads, when summer comes along
it becomes a furnance :mad:

their is no chance of split, cassette, or underfloor cooling due to the design of the house.
BUT there is space above the kitchen cupboard and behind that lies a void where i can pick up power and drainage ONLY

No room to run pipes to external unit (condenser) roof top cant be drillled through either

So my only option is to install a unit primarily above the cupboard where there is enough room for a concealed bulk head type unit.. BUT it needs to be packaged (all in one)

are they available?? aussies wb only

Regardless of unit you will need access to outside of the room for the hot air discharged from the condenser.
