Hi, first time poster here. I have a basement family room that is never used because getting to it is a hassle. Right now, to get to the basement (and backyard) you go through a door at the back of the garage. This means to go from the kitchen/dining room to the basement (top level) or from the master you have to go through the laundry and around a parked car (see purple line in middle diagram).

We've met with an architect to look into getting stairs to access to this room without going through the garage. I'm attaching the preliminary plans. Originally we talked about putting stairs parallel to the far right wall, but this would cause us to significantly lose footage in the master. Recently it dawned on everyone that it didn't make sense to make a third set of stairs. The new plan is to push the master wall in 8" and create a hallway connecting one end of the house to the other (see last diagram). The garage stairs would be redone so they look more like inside stairs.

We'll lose the big walk-in closet, but with the auxiliary closets that will be added along the hallway we'll end up with more closet space then before. When it's just my husband and I, everything will be open so the hallway and auxiliary closets will seem like they are part of the master suite. When visitors come, we can close doors and maintain privacy as people move down the hall. Other ideas I'm throwing around are a dumbwaiter to send things downstairs (e.g., grilling supplies) and expanding the bathroom into the master bedroom so there could be two sinks instead of a single. Is the double vanity worth it?

In the basement room, there is currently a locked door (outlined in blue). We'd remove it so the stairs would flow into the room. Right by there (at the bottom of the to-be redone stairs) is a door to the backyard. I'd like a sliding door out the to patio from within the family room, which is doable. But it was suggested I keep the other door too so garden waste can be brought to the curb without trekking through the family room. Will it look strange to have a door, sliding door, and window all one half of the house - Maybe I should get rid of the window?

Sorry for making this so long. I guess mostly I'm looking for feedback to see if there is anything I am missing on why this might be a bad plan. We think this will help (or at least not harm) the resale value in the (far) future since it makes the basement accessible - in 6 months of living in the house, we've used the room less than a dozen times. But maybe we're wrong.
