The old building
funds the new one.

Upload the plans of the building you're demolishing and the one replacing it. Rebilder identifies the recoverable materials, matches them to your new build, and reduces your total construction cost — automatically.

How it works

Four steps. One result.

Everything from file upload to cost saving happens inside Rebilder. Click each step to see it in detail.

Two sets of plans in.

Upload the construction files of the building being demolished and the one replacing it. Rebilder accepts the formats your team already works with.

Revit (.rvt), IFC, DWG, DXF
Excel-based material schedules (.xlsx)
No plugins or BIM software required
Or enter materials manually in under two minutes

Every material. Quantified.

Rebilder reads the old building and identifies every material type and quantity — along with how much of each is realistically recoverable in reusable condition.

Bricks, timber, concrete, steel, sand and more
Recovery yields applied per material type
Reuse potential rated: High / Medium / Low
Embodied carbon calculated per material
Bricks — 80 m³
85%
Timber — 45 m³
70%
Concrete — 200 m³
60%
Sand — 30 t
50%

Matched to your new build.

Recovered materials are automatically allocated against what the new structure needs. The saving is calculated instantly — and split fairly between you and your client.

Material-by-material cross-match
Purchase cost eliminated on every reused unit
Saving split between client and contractor (adjustable)

Why it matters

The numbers behind the problem.

Construction and demolition generate the largest waste stream in Europe. These are the figures from official published sources.

~37%
of global CO₂ emissions come from the buildings and construction sector
UNEP, Building Materials and the Climate, 2023
76Mt
of construction & demolition waste generated in Germany per year (Destatis, 2024)

<30%
of recovered C&D material re-enters as actual building material — the gap Rebilder addresses

Why now

Europe has committed.
The industry must follow.

Every contractor, architect and developer in Europe will be required to measure and reduce the embodied carbon in their buildings. Rebilder provides the material data to do it — from the moment the old building comes down.

2030
−55% GHG emissions
All new buildings must be zero-emission. Whole-life carbon reporting mandatory. EU Climate Law.
2040
−90% GHG emissions
European Parliament voted Nov 2025 to amend the EU Climate Law and add this target.
2050
Climate neutral
All existing buildings zero-emission. Germany's Digital Building Resource Passport in force.
Rebilder outputs align to the EU Resource Passport and UK embodied-carbon reporting requirements
