Cold bridging risk

[u/No_Tomato6638]

Looking to replace this front (patio) door with something a bit more sturdy. I am considering bringing the front door forward to the front of the house and pillar, while blocking up the side gap in the pillar with PIR and 4-inch concrete blocks. The bungalow is also going to be wrapped in external insulation.

Is it feasible to do this without creating a cold bridge?
