symmetrical abs?

Of course many people have asymmetrical abs(non symmetrical) because of nature. Also playing a sport like tennis can also result in uneven muscle use between the left and right sides of the body. Since muscles can only contract/pull not push, so for instance I think the left sided abs are used more than the right sided ones when serving for right handers.

What exercises can be done to develop just one side of the abs muscles?
 
Bad idea. Most exercises for the abs also bring into play back and intercostal muscles as you return to position between reps. Start to develop assymetry of back muscles and you may wind up with far greater problems than you bargained for.

At the moment I do straight forward crunches and back raises to try and equalise opposing muscle groups. What would you suggest regarding building up the less developed side?

I agree with El Diablo.

You don't have to worry about your left side of you abs wil be less developed than the right side because of serving.

What you should do is to do exercises for every part of your midsection.

You are already doing crunches and back raises.

Now you could do side bend and twisting exercise such as reverse trunk twist or russian twist for your obliques.

The right way to do side bend on the floor :

Lie on you side on the floor. Have an assistant sit on your feet and place his hands on your upper thigh or hips to keep them in place. Cross your hands on the chest and keep your head in proper alignment with the trunk.

When ready, raise your trunk sideways as high as possible. Be sure that the trunk remains in the side plane at all times. When reaching the upper most position, return to the original position and repeat.

As I have mentioned in my other post, side bend directly involve the obliques and quadratum lumborum muscles. The development of quadratum lumborum is needed for lateral stabiity of the spine and prevents your spine from curving to the left or right, resulting in scoliosis. However, because the quadratus lumborum is a deep muscle, it cannot be felt or seen. But its role is critical to a safe, pain-free lower back.

if you work both equally, the weaker side will grow ALOT faster (Faster doesnt mean fast, just means faster than the stronger side)

a lot of its genetics too
I mentioned that in the first sentence of the first post. Unlike arm or leg exercises whereby we can just work the one arm/leg, one side of the abs can't be worked in isolation, the otherside will always do some of the work. It's difficult preventing the dominate side from doing the majority of the work.
