Is there a Terran wall-in guide?

Does some kind of Terran wall-in guide exist that focuses on the different ramp types. I struggle with some of the strange 2v2 ramps, especially if they face northeast and I want addons on my Barracks very fast.

Sometimes my wall is not complete or the buildings are weirdly paced so my units cannot defend very well as the buildings take up too much space. Other times my ally helps me wall-in but he places his buildings so I cannot add addons without breaking the wall.

I always think that I am at a disadvantage if my base faces northeast.

Solution 1:

Make sure that the building grid is enabled in Options, that will help you place buildings on the fly without having to memorise anything.

As for your ally blocking addons, your best bet is to lift the building and build the addon elsewhere when you're ready, while replacing it in the wall with supply depots. Alternatively, you could use the Voice over IP client to plan out your wall in with your ally.
