Profile
bauwerkplus+ is the architectural office of Christian Bayer, M.Sc. (FH), Architect and City Planner, based at Westendstraße 91 in Munich. For over 20 years, the focus has been on building in existing structures: renovations and expansions, general renovations, attic extensions, annexes, and roof extensions, as well as changes of use, for example, from offices to doctor's practices or apartments. The office accompanies projects through all HOAI performance phases from 0 to IX, from consulting before acquiring an existing property to planning and obtaining offers, and construction management. Clients include private clients (residential construction) as well as medical practices such as dental practices with dental laboratories, general practitioners, and neurological specialists. Typical building materials in the project environment include wood (larch, timber frame), steel, concrete, copper, and ecological insulation materials such as cellulose and wood fiber insulation.
