Uncrowded

I know many synonyms for the word crowded like congested, populated, populous, packed, full, overflowing, swarming, teeming, thronged , cramped and so forth.

But interestingly I can't think of any synonym for the word uncrowded. I wonder why English language is like this. many words for one concept and few for its opposite.

Can anyone provide me some synonyms for the word uncrowded.

Thanks for your time and help in advance
