I really like this pack, but I tend to build smaller homes for 1-2 Sims plus 1-2 pets anyway. With the perks, it was a challenge to build smaller than I'm accustomed to. My latest build really taught me what is necessary and what isn't for a 64 square build. On a 15x20 lot, I can still have a small backyard that has room for a barbecue area, a hot tub, an easel, and a lounge chair for tanning. Everything else my Sim does can be done in either the main living area, and the kitchen and spare room on the other side is only 3x4.
The hairs are not my style, but the sweaters are really good if you have other packs. The furniture is really nice if Mid Century Modern is your thing.
The Murphy bed is not a problem as long as you upgrade it right away. The first upgrade alone may prevent your game ending in less than 24 Sim hours. If you have a Tier 2 (64 square) home, you can get to Level 3 handiness really quick on the first day.
