I'm Taking Small-Space Notes From This Family of 4 in a 450-Square-Foot Studio

Let me be frank: I live in a one-bedroom, decently-sized Manhattan apartment with my husband and three pets. I have a proper living room, a kitchen with elongated cabinets for extra storage, and I have installed small-space hacks, like wall-mounted clothing racks, for ample functionality. However, I still feel like its bursting at the seams.
