Not to worry. We made a couch surf on an (insulated) porch for a joke. It’s had 25 five stars! Guys love it. All it really needs is confidence!
HI I agree with much of what you are saying. Might I also suggest to use the drawered unit as a coffee bar. It might also be strong enough to hold the fridge or put the fridge beside it. I would prefer to move the couch over to the other wall where the drawer unit is so the bed can be accessed from both sides. You can also get wall outlets that have a built in breaker. They are commonly used in bathrooms and may help with your electrical concerns. Cheers.
