The individual or luxury home builder does not want to be confined by restrictions of a one meter module system.
We know of no ground plan for a modern house necessitating a module of increments of less than 5 cm.
For the elevations, Styro Stone permits increments down to 2.5 cm.
If your original plans do not conform, your architect will in all likelihood have used a CAD Programme so that your plans can be easily modified at little or no extra cost.
Every Styrostone is line embossed at 5 cm intervals to facilitate the cutting of the blocks to the correct length.
A house designed on the basis of Standard Stone widths of 25 and 35 cm involves less cutting, thus less labour on site, providing yet another economy.
Rule of thumb:
Every dimension divisible by 25 cm saves time and labour on site.
Every dimension divisible by 5 cm increases time and labour on site.
Any dimension not divisble into modules of 25 cm or 5 cm, appreciably increases time and labour on site.
