Building with bricks

Hi all,

In general terms, how would I go about this process (if it is even possible):

• I have several prefabs (meshes) that you can basically think of as bricks in a wall (some are different shapes and sizes etc)
• In code, I would like to stack several of these together in a line, then treat them as a single mesh and apply a texture to the whole lot.
• If possible, I would still want the bricks to be separate objects so that I can later break the wall apart and move the bricks around.

Any help appreciated.
