Looking into getting a 3d printer and I'm aware that an enclosure with PLA is unadvisable due to heat creep but was hoping if there was a way to use an enclosure regardless.

I'll be in the same room as the printer for extended periods of time if not the whole time and though I know that there is mixed info on how harmless PLA is, I would like to err on the side of caution and exhaust everything outside as it will be next to a window anyway.

Would a single exhaust out the window be enough? or perhaps adding an intake fan also? I live in the UK so the weather doesn't get too extreme.

Honestly, this is going to depend on what printer you have. I have (and would recommend) a Bambu Labs A1 Mini, and you can get something like this for it: 3D Printer Enclosure for Bambu Lab A1, A1 Mini. Just look for something with good reviews for your printer.

PLA isn't toxic (at least, for what matters), so a single exhaust out a window would be fine. However, you might want to get a fan if you're printing things like ABS.

A 8 cm fan running continuously at the top of the enclosure will be more than enough to vent air out, provided you have another 8 cm opening at the bottom of the enclosure to let air in, and PLA won't soften.

I have a Q1 Pro with a 6 cm exhaust fan located on the back side, about as high as the print head, and when it runs at max speed with the door open, top cover closed the temperature in the chamber stays at about 30 °C, and no issues with printing. If you place a larger fan and on the top cover instead of rear side, you'll be cooling even better.
