Hello there! (And a bit belated
!!)
All of my orchids are grown on a windowsill - the kitchen, the dining room, and my 'side porch'/utility room which has lots of windows - just like you.
I will bring plants in bloom into the lounge to enjoy them and for the most part, the plants don't seem to mind too much. I do keep them away from extremes of temperature (so not too close to the radiators) and I check a bit more regularly to see if they need water. They tend to dry out a bit quicker in the lounge, so may need to be watered a bit quicker than the others.
I have found that they work well on the mantlepiece when in flower, or on an end table by the sofa. They also work really well as a centerpiece on the dining table. ...just some thoughts....
