One of the two sides of Aa: Phase 5 has been the planner for every Alfons & alfreda project to date. Mostly as a general planner.

Phase 5 is the technical side of the venture.

Fused by a strong entrepreneurial spirit and in collaboration with Aa's team, the architects at Phase 5 form a strong unit that always develops pragmatic, goal-oriented solutions through a long-standing interweaving at a stakeholder level.

Phase 5 has many years of experience as a (general) planner in the residential and office area as well as the logistics sector and ensures our technical know-how across all projects.

With over 75 employees, a supporting partner office in Berlin and countless external project partners and specialists, the architectural firm has realised over 300 projects. Formed in 1991, Phase 5 belongs to one of the leading planners in Germany.
