Open-concept remorse?

I think you should go both with your gut and marry in a bit of what your architect or contractor might recommend. I also think you should consider which exposure you have. You may be getting all day light and removing every last wall might not be necessary. I think you should consider who your tenants might be; are you considering young professionals, students or families? I believe there is a way to honor the history of the house and stay true to what you feel is right but still open up archways and maybe remove a wall or two that is non-load bearing to get the things your house needs (more storage, a bigger bathroom or kitchen or a bedroom that can host a king sized bed and side tables). Lastly think of the more important things like the mechanicals, what may happen removing so many walls and soundproofing, HVAC, etc. I am a fan of open and airy spaces but too many Reno’s look like padded cells or blank white boxes. Find the happy medium.
