I am building a small (75' long, 3' tall) retaining wall using Anchor compac blocks. I have built walls using this product before but have never come across the need for an inside 90 degree corner. This wall will come out directly from the foundation of the house for 15' and then take a 90 degree left hand turn. any thoughts on how to make this as neat and structurally sound as possible? also, should I start at the corner and work my way out for the base course? Its is level across the length so there is no low point to start from. I know I can figure it out once I am there, but I want to get some tips and pointers from the experts ahead of time. BTW, the wall is going to be vertical and not stepped back at all. Thanks in advance.
