Building brick walls on a concrete floor

[eric-dashan]

Hello. I have a carport (see image here: http://i33.photobucket.com/albums/d57/daishancaca/fl007a.jpg ) and plan to alter it into a store room by building brick walls, replacing the current wooden gate and the wooden fence on the side. The carport is on a concrete ground, leveled, and the wall will be arouond 2.6m high, reaching the ceiling of the carport.

A few questions:
1) Can I build the brick walls on the surface of the current concrete ground? Do I need to dig the ground and build a separate concrete foundation for the new walls?
2) Would there be other options of walls (like wood wall?!) that I can avoid digging open the current concrete ground?
3) Is there any related articles on this topic available online?

Many thanks. I appreciate any suggestions.

i would be inclined to dig strip foundations for a wall of that size, unless the floor of the garage was a reinforced raft with a strengthened toe beam.

If just for storage I would be inclined to build a timber frame on a low brick wall, basically an attached shed.

Thank you both for the suggestions. Then my new questions are:

1) Am I allowed to DIY the digging, for strip foundations? If yes, what machine should I be looking for to dig the concrete ground?

2) If building a timber frame on a low brick wall, how deep the foundation would be needed for the brick wall?

Many thanks
