Have you considered purchasing your own weight rack?

Rogue sells a few pre-made one's that fold into the wall and occupy little space. It's a larger upfront investment but you can have free weight gear in your house and it will pay for itself fast.

If you're outside the USA, you can usually find a local welder / shop to make one for you.

Outside of strength training, you could go for long walks (I enjoy these).

If you find a fun community, Acro, BJJ, Climbing, Dance, Football / Soccer etc, you might have your day made.

You could also box more often.
