Mivel vélelmezem, hogy az előző építészeti /ingatlanos kérdéshez kapcsolódik, a rebuildingre szavaznék, mert bár szó szerint Péter megadta a választ, itt gyakorlatilag egy adott épület/ház/ingatlan újjáépítési értékről van szó (vagy legalábbis az előzőek után ezt gondolom, de szólj, ha tévedek), csak a szerző iszonyúan fogalmaz (ezt még egy született magyarnak is igen nehéz lenne fordítani)

These calculators can be useful for working out how much cover you need, but not all calculators are the same. They use two different methods to estimate rebuilding costs:

Cost per square metre - this method provides a rough guide that should not be relied on and is based on the size of the house and the materials used
Elemental estimating - assesses in detail the different elements of the building to calculate rebuilding costs from the ground up, using local wage and material rates and other construction data
Cost per square metre calculators will ask you less than 10 questions and may not take into account all the features of your home. They are likely to give you an average figure that could be too high or too low.

The more basic calculators are limited because they apply an average figure to each house. They don't take into account features that can increase rebuilding costs, such as whether your home is built on a slope, has higher quality finishings or is more than 40 years old.

The results can vary greatly from calculator to calculator. So it pays to be aware that there are differences between calculators, and that some are more reliable than others.

Hát persze, ha össze akar dőlni a ház, vagy ázik a tető...
