was the kitchen or living room an add on addition and the exterior brick wall was left up as part of the addition or is it a fake brick wall?
What country are you in? - The heating, cooling and electrical outlets suggest that question.
The only brick I see are just surface tiles applied for a backsplash above the countertop.
Is the wall you want to open up made of masonry (brick, block, clay tile) or is a framed wall using steel studs or wood?
You definitely have a lot of electrical and heating/cooling in the wall you want to remove. It would be good to have a local professional look at the situation to determine the feasibility. the concept would certain open up the small spaces into a larger one.
