P+ Architekten Ingenieure

What P+ Architekten Ingenieure does

P+ Architekten Ingenieure is a German architectural and engineering firm founded in 2013 by Heiko Pihl and headquartered in Dortmund, North Rhine-Westphalia. The firm operates as a full-service planning practice under the HOAI § 34 framework, delivering architectural and engineering services across the building lifecycle with a methodology anchored in Building Information Modelling (BIM) from 3D through 7D. It specializes in sustainable construction, holding DGNB membership (since February 2024), DGNB Auditor certification for its founder (May 2024), and STI certification for in-house BNB and QNG submission capability.

The firm serves primarily public-sector clients — municipalities, schools, sports halls, and civic infrastructure — across the Metropole Ruhr region, with project footprints extending into Köln, Düsseldorf, and Mannheim. Notable engagements include a multi-year framework contract with AOK NORDWEST valued at approximately €2.9 million, a 1st-prize win in a 2019 residential-housing competition, and 40+ completed projects since founding. Its customer mix also includes private developers such as B&L Gruppe.

The business model is project- and framework-based, monetized through HOAI fee structures for architectural and engineering services. Revenue is generated via competition wins, direct public-sector tenders, and multi-year framework agreements; the firm is bootstrapped with no external funding and employs approximately 15-18 staff as of 2024-2026, with active recruitment underway. Its go-to-market leans on certified-sustainability expertise, BIM lifecycle methodology, and a competition track record as differentiation against larger German generalist practices.
