Building design
Concept, preliminary and detailed design for residential, commercial and public buildings.
Engineering that turns your building project into a sound plan.
Oltmanns und Partner GmbH is an engineering office in Oldenburg. We design buildings and engineering structures, from the first concept to the documents your contractors build from.
A local engineering office with a clear way of working
We plan buildings and engineering structures for private clients, developers and public bodies in Oldenburg and the surrounding region.
Our approach is simple: we listen first, plan carefully and document everything so that costs, deadlines and responsibilities stay visible throughout the project.
- Based at Infanterieweg 9A, Oldenburg (Oldb)
- One point of contact from brief to handover
- Plans that follow current German standards and regulations
