Thank you for posting. There are multiple ways to do it.
The simplest way is to modify your theme sidebar and use the widget area conditionally.
In future, within 10 days, I am also releasing an addon for WooSidebars plugin, that allows using any sidebar conditionally. I had originally worked on it for a theme of ours and plan to put it for public soon.
For now, you can use bp_is_group() to check if you are on group.
1. I have the woo sidebars addon almost ready and will release in next couple of days. before going with WooSidebars, I had looked at multiple solutions to provide flexibility with Community Builder. This plugin seemed to be simple/clean coded and highly flexible, so choose it.
As George suggest in the post above, if you only want to show/hide widgets(not sidebar), you may try the above mentioned plugin too.
