Groundwerk is a property intelligence platform for home buyers in the Netherlands. We pull data from 20+ official Dutch government databases and turn it into clear, actionable reports.

How much does it cost?

Your first report is completely free with all sections included. Additional reports are €9.99 each. The Search Pass (€39.99) gives 3 months unlimited.

Does it work for any property in the Netherlands?

Yes. Groundwerk works for any residential address in the Netherlands.

WOZ is the government-assessed property value, updated annually by the municipality. Used for property tax calculations.

What data sources do you use?

BAG, CBS, EP-online, PDOK, Kadaster, Leefbaarometer, Klimaatatlas, RIVM, DUO, and more. 20+ official sources in total.

Is Groundwerk useful for expats?

Very much so. The Dutch property system has specific concepts like erfpacht, VvE, and overdrachtsbelasting that can trip up international buyers. Groundwerk explains these in plain English.

Buying in the Netherlands?

Bidding without data

You don’t know what the property is actually worth — or whether the asking price is fair for the neighbourhood.

Most properties sell above asking price, sometimes up to 10% over.

Hidden risks you can’t see

Foundation problems, asbestos, outdated wiring — Dutch pre-war buildings have specific risks that aren’t in the listing.

Structural issues can cost tens of thousands to fix — and sellers aren’t required to disclose everything.

VvE and ground lease pitfalls

The VvE (homeowners association) and erfpacht (ground lease) are unique to Dutch property — and can add thousands in hidden annual costs.

Most Amsterdam apartments are on ground lease, and many VvE funds are underfunded.

How it works

Paste the property listing

Copy the property description from Funda (the main Dutch listing site) and enter the address.

We fetch the data

Groundwerk automatically queries BAG, EP-online, CBS and other official sources.
