The concern

We no longer know what condition the house is really in.

What we did

Systematic inspection, photo documentation, prioritisation of investments.

What was the goal?

An honest assessment as the basis for every next step.

What was the initial situation?

Those who live in their own house for years become accustomed to its condition and eventually lose their critical perspective. Only when renovations are needed, a sale becomes concrete, or a change of use is planned, does the question arise anew: What is the true condition of the building? An honest assessment is the foundation upon which all further steps are built.

Finally, we know where the money really belongs in the coming years.

Ownership, Zurich region

What have we accomplished?

I systematically went through the house, room by room, from the basement to the attic, documenting each finding with photos and descriptions. I compared the condition with the project documentation from the construction phase and checked the land registry extract for relevant entries. The result was a structured report to serve as a basis for all further considerations.

What was the result?

The owners ultimately had an honest inventory as a basis for every further step, whether refurbishment, sale or repurposing, and no longer had to rely on gut feeling.
