Hello! I thought I understood our building plan... For example, if one side of the house is specified as 11.50 meters (38 feet) in the detailed plan, does that measurement include the insulation (14 cm (5.5 inches) on each side) or not? I read the plan as showing the 11.50 meters as the exact boundary of the exterior walls. Then there is a line on the plan with the 14 cm (5.5 inches) insulation marked on the outside, left and right. However, the structural builder now claims that the dimension includes the insulation. Strangely, we are missing about 25–30 cm (10–12 inches) on the ground floor!
How does it usually work in practice? Is it 11.50 meters plus 2 times 14 cm insulation (which is how I read it), or 11.50 meters including the 2 times 14 cm insulation?

I have attached the execution plan (which is likely what you call the detailed construction plan) for one of our ground floors for your better understanding.
The outermost lines indicate the absolute width/length of the ground floor, while the line below (towards the masonry) shows the measurement including the breakdown of masonry plus the outer plaster layer. We build purely monolithically, so this value is relatively low at 2.5 cm (1 inch).
If your plans look similar—which I assume since this is common practice—the shell builder is absolutely right. All of us (all suppliers) usually maximize the building envelope approved by the local building authorities; these must not be exceeded by the insulation system.
However, aside from that, there should be a proper contract or at least a building permit (also called planning permission) that clearly states these measurements. The values from the execution plan should be consistent with those in that documentation.
Best regards, Bauexperte

Hello! I thought I understood our building plan... For example, if one side of the house is shown as 11.50 meters (37 feet 9 inches) in the detailed construction plan, does that measurement include or exclude the insulation (14 cm (5.5 inches) on each side)? I read the plan as meaning that the 11.50 meters represent exactly the outer edges of the exterior walls. Then there is a line on the plan, and outside of that line on both the right and left sides is the 14 cm (5.5 inches) for the insulation. However, the shell builder claims that the measurement already includes the insulation. Strangely, we are missing about 25–30 cm (10–12 inches) on the ground floor! How does this work in practice? Is it 11.50 plus 2 × 14 cm (5.5 inches) insulation (which is how I interpret it) or 11.50 meters including the 2 × 14 cm (5.5 inches) insulation?

perlenmann28 Oct 2013 10:49What exactly are you talking about? At one point you mention 14cm (5.5 inches) insulation, then monolithic construction.
If I take your 25-30cm (10-12 inches) and then 14cm (5.5 inches) times 2, that gives us 28cm (11 inches).
If I calculate your 10.70m (35 feet) interior in the basement, plus the insulation that is probably present in the basement—28cm (11 inches)—I round that up to 11m (36 feet) plus 2 exterior walls at 25cm (10 inches) each, which makes a total of 11.5m (38 feet).
