This will vary depending on the construction method of the walls. Interior walls are usually about 41/2 inches thick and exterior walls around 61/2 inches. If youâre about to draw floor plans for an existing home measure the thickness of the walls at the doors and/or windows. Next we move inside. It makes sense to start on the main floor.
The width of the foundation should be twice that of the width of the wall you are building and the wall should be placed in the centre of the foundation. If you need to build a wall 225mm wide the foundation should be 450mm wide.This will give you a foundation overlap of 112mm either side of the finished wall.To work out how thick the wall needs to be (A) you must first work out how deep the garden will be (B) at the point you plan to build the wall.hen you have measured how deep the garden will be you simply divide it by 4 to get the required thickness of wall. If your retaining wall is holding back a 1m depth of garden then it needs to be 225mm thick. The minimum thickness of a garden retaining wall should be the width of a standard brick @ 112mm.
