It's a large 2 story loft space. It has a full kitchen (as most offices do too these days), and 2 full bathrooms. There is a loft bedroom and small closed off office space that are both conference rooms when it's in office mode.

Really, how different are offices from apartments? You have space, kitchen, bathrooms, etc.

The only thing that is weird is most offices don't have a washer and dryer, other than that if I walked in this space and it was decorated as an office I wouldn't think twice, same in apartment mode.

Does it scale down? I can see two floors of an office building making a (very expensive) apartment but what about a cheap 1 bedroom? In "office mode", the office unit would be < 50% office, with most of the floor plan as bathrooms, laundry, and kitchen.

Not really.

I would argue that I live in a cheap 1 bedroom, it exactly this that you describe.

The bathrooms are a wash, both commercial and residential spaces require them. If anything the bathrooms in this arrangement are a bit smaller than traditional commercial bathrooms.

Same with the kitchen, commercial spaces have them, every place I've worked for the last 15 years has had one. So that's a wash. Also, our kitchen isn't huge, it's of similar size to those kitchens.

That leaves the laundry. For us it's a stacked unit in a small closet in the bathroom. They could easily be removed and then the closet could be used for bathroom cleaning supplies and no-one would ever suspect it wasn't just an office.

So the real comparison is: Residential: 1500 Sq ft loft, small glass office and loft bedroom, 2 full baths Commercial: 1500 Sq ft office, 1 large loft conference room, 1 small glass conference room/office, open Floorplan for 10-15 desks, 2 bathrooms with shower, full kitchen Both have door service, package receiving and security services provided on site, parking space
