Our surveys include a scale plan of the building, notes on wall thicknesses and suggested dates for the different phases of building.  \nIt has long been known that changes in wall thickness are a good indicator that the building had differing phases of construction, however no one could tell me why this was the case. There is little written about how wall thickness’s were determined by the original builders. Suggestions that it might be based on daisy wheels or other geometrical forms have been extensively tested, without any success. They get over complicated very quickly.  \nThe actual solution to the wall thickness problem is a very simple and obvious one. The wall thickness is always a simple multiple of the units used to set out the building. It is likely that for timber buildings, with thinner walls, this will be a division of the units.  \nMethod of analysis  \nThe analysis uses CAD and drawings are scaled to full size using the scale bar for reference. This allows the drawing to be measured directly. These measurements can then be entered into a computer program that suggests possible units to consider and how accurate the match is. I keep the original names of measurements as I find them.  \nA grid, using the appropriate units is then applied to the drawing. I do not think for a minute that the carpenters laid out a grid when designing the building. They would have used simple measurements with a measuring stick. The grid allows me to easily see alignments with the measurements and the building. It is possible to identify areas of later construction or modification. It also helps to bring order and make sense of complicated layouts.  \nThere are many issues that can make applying grids difficult.  \n• Later works in different units of measurement, although grids can be used to identify different phases of work.  \n• Poor or inaccurate survey drawings, or inaccurate scale bars.  \nSimply applying a grid to a building or landscape is rather dangerous as you get lots of false positive results. A building plan can show alignments with a number of different sizes of grid. To identify the correct units some basic rules need to be followed.  \nRules for using grids correctly  \n1. As well as short distances matching the grid, there must be alignment with the grid overlong distances so any error in the unit of measurement is magnified. Ideally a number of long measurements should be examined to ensure random alignments are not being detected. An example might be the the length and width of the building.  \n2. The grid must be able to pick up detail over short distances, to confirm the units are correct. Examples might be wall thicknesses or other small structural details.  \n3. Wall thicknesses are always a simple multiple of the basic units of measurement, however in Somerset early cob walls are often replaced by thinner walls in stone, so some commonsense needs to be applied. Generally the internal span stays the same, so floor beams can be reused, with changes being made to the external dimensions. These can often be seen as exposed areas of foundation, wall plate or timbers projecting out of the wall.  \n4. Only measurements based on known historic units are used. Random distances are not considered. Longer measurements are subdivided by 12, 10 or 8 to give practical units for construction.  \n5. Any unit of measurement needs to be found in multiple buildings before it can be accepted as being correct.  \nUnits of measurement found in buildings.  \nThe vernacular houses of Somerset are generally jointed crucks with thatched roofs. Initially they would have had cob walls. Frequently these have been replaced in stone. The initial cob builds are usually set out in 740mm units of measurement.
