Small brick wall surrounding the front garden

[kinsden]

Hi All,

I am planning to put a small brick wall (2 feet high and 10 feet long) as a boundary marker in my front lawn. Have few queries regarding the same:

1) For a wall of such a height, how deep would you recommend a foundation to be? Mind you, its just a single brick wall acting as a fence; won't be taking any heavy loads.

2) Will engineering bricks do just fine for the task?

3) For a 10-12 feet long brick wall, at what intervals do I need to build the piers?!

TIA for the help!!
