How it works

Four guided steps. An expert at the end.

It feels like a conversation, not a form. A progress bar always shows where you are, an AI assistant supports you, and a reviewer from our Brussels office signs the report before it reaches you.

01

The four steps.

01

The property

The rooms

Tell us which rooms are involved and their area. The m² feeds the take-off and the ABEX pricing behind the scenes.

The components

Pick the items to renovate — or describe them in the chat and let the assistant suggest the packages to confirm.

A stepper, a progress bar,
and an assistant by your side.

Here is the real intake. The sidebar tracks your progress, the centre asks one clear question at a time, and the assistant turns a sentence into work packages you approve.

Hi there! Describe your renovation and I'll prepare your estimate.
1924 house, pretty cold. We want to insulate it well and replace the old gas boiler.
Got it. For a 1924 façade I'm adding wall insulation and a heat pump. A pre-1990 building almost always needs type D ventilation once it's sealed.

The machine structures.
An expert stands behind the figure.

AI is fast and consistent — perfect for structuring the scope and aligning it with the ABEX index. But nothing leaves the building auto-generated.

Step A · AI

Structured & costed, in seconds.

The engine turns your answers into line items, aligns them with the ABEX index, finds the subsidies and builds the energy trajectory — in seconds.

Step B · Expert

Reviewed & signed in Brussels.

A reviewer checks the assumptions, corrects what the machine misses, and signs. Their name is on the report — that's the difference a bank notices.

In twenty minutes, you could be holding the PDF.
