A clothes airer/clothes horse. And the 6' long baby gate. And the backs of chairs. Shirts and blouses are put on hangers and hung from the archway between the sitting room and the kitchen. When we were in a tiny studio flat, the airer and the bath were used.

I also put emergency clothes over radiators just so they get that little bit more heat. But if it's dry and windy, so long as it's above freezing the washing goes out. Gives it that little bit more help.

Worst case, there's always the dryer.
