How Bauwsteen Aligns Buyers, Suppliers and Contractors with Ziggu

Bauwsteen is a customer-care coordinator for property developers. Owner Judith Wauman guides homebuyers through residential projects, including projects for developer Alychlo. Since 2024, Bauwsteen has run that guidance through Ziggu: documents, decisions and approvals sit in one customer portal. Judith Wauman guides up to 120 units per year, compared to 70-80 before.

What does Bauwsteen do on a residential project?

Bauwsteen coordinates customer care on other companies’ projects. Judith Wauman is the person a buyer calls when they want to know whether a change to their kitchen is still possible. She is also the person the site team calls when they need to know which plan is final.

Her clients are property developers, among them Alychlo. That distinction matters: Judith does not develop the buildings, she carries the communication that runs alongside them, from the first choice a buyer makes to the day the contractor starts work.

Every choice a buyer makes has a technical, a financial and an operational consequence. A selection made in a showroom has to be validated, priced, approved and handed to the contractor before execution. Judith works at the point where those lines cross.

What was slowing that work down?

Before Ziggu, the information Bauwsteen needed sat in other people’s mailboxes. Showrooms sent proposals by email. Buyers replied to whoever had written to them last. Approvals lived somewhere in a thread, and nobody could prove which version of a plan was the current one.

The cost of that is not administrative. It is rework on site, a delay in the planning, an extra invoice, and a buyer who feels badly informed about the most expensive purchase of their life.

“99.99% of mistakes are caused by poor communication. With Ziggu, many errors can be prevented through clearer communication with clients and contractors”, says Judith Wauman, owner of Bauwsteen.

How does Bauwsteen use Ziggu?

Bauwsteen keeps one dossier per home, and everyone works inside it. Buyers find their plans, their documents and their next steps in the customer portal. Showrooms upload their proposals to the same place. Contractors and subcontractors see the approved version, and only the approved version.

Judith works from the project overview: what has been decided, what is still open, and who is holding it up. An update goes out once, to everyone who needs it, instead of three times to three inboxes.

How do customisations get approved?

The customisation phase is where a residential project usually comes apart. Buyers make personal choices, showrooms turn those into proposals, someone has to check that the choice is technically possible, and the contractor needs a final answer.

In Ziggu, every choice is recorded centrally, with a date and a name against it. The approval sits with the choice. When the contractor opens the dossier, there is one version of the plan and no discussion about which one it is.

What changed?

Capacity. Judith Wauman guides up to 120 units per year, compared to 70-80 before, and she does it without adding a colleague or an administrative layer.

The second change is quieter and matters as much. Nobody has to reconstruct a decision from an email thread. Buyers ask fewer repeat questions because the answer is already in their dossier. And when a developer asks Judith where a unit stands, she opens the project and reads it off.
