Our practice


As an established practice in its second generation in Essen, our office is based in the heart of the Ruhr metropolitan region. KZA draws its strength, capacity for innovation and individuality from this dynamic place.

Our team

Our practice is of a size that means we can assemble the ideal team for each assignment, for each client and their requirements. Some of our colleagues have been with KZA for a great many years. They have the skills necessary to reliably and creatively accomplish the assigned tasks – from the first sketch to the finished building. We’ve been working with collaborative 3D BIMs (building information models) since 2015, too.

Project management

The building blocks of project management

Experienced project management underlies every construction and planning task: starting with a kick-off meeting and an organigram of the planning and site management team. We professionally prepare for and follow up planning and coordination meetings and ensure planning and cost management quality by means of internal checkpoints. It goes without saying that we regularly monitor costs and deadlines and keep our clients informed about the current state of progress with monthly status reports. In addition to this, we document every work stage in a final report. We manage changes with decision memos and lists of outstanding issues, and finally supervise and monitor construction sites and offer a suitable health and safety coordination service.

The thing that connects planning and site management is the close scrutiny of a project's costs and economic key figures. From inception and throughout all stages. I would never have imagined I'd enjoy it so much!
