What this site can do - and what it can't
This overview does not replace a property inspection, an investment calculation, a technical construction inspection or a binding construction offer. It clarifies the entry point. The actual work begins when the object, objective, documents, budget and responsibilities are available.
Practical classification: Separating the module, bottleneck and documents early on saves queries, loops and false expectations. That sounds sober, but it is often the difference between a clean start and months of "we'll see".
