Wall starter plates

[Lawrence Zarb]

I intend to build a 215mm solid block wall. Do I need to use 2 wall start plates, as below

parallel (side by side) or will one suffice

I've never understood the benefit of using these things. They were intended to avoid cutting toothings in existing walls, but a few plugs and screws aren't going to give anywhere near as much lateral restraint - you might just as well screw a few cheap frame cramps to the old wall.

They are intended to allow movement, as is likely when you put a new building next to an old one on separate foundations.
