There are several neighborhoods in the Norman area that offer community pools, clubhouses, etc. Of course it will depend on your price point. In my opinion one of the nicest moderately priced neighborhoods in Norman with these amenities would be Saint James Park off 24th and Highway 9. This neighborhood offers a great pool, Clubhouse, and excersise area if I remember correctly. There is also Sutton Place off Porter and Robinson. This is another great moderately priced neighborhood.
If you are looking on the west side of town there is Berkely, Castlerock, Carrington and Cascade off 36th.
there really are too many to go into too much detail here. If you would like more info on what is available that would suit your specific needs please give me a call anytime to discuss. I would be happy to point you in the right direction. I hope this helps.
