What we do

We program buildings

We create algorhithms that define the architectural form of a building. The programmed shape provides the exact geometry in arbitrary-precision so that all constructions within the building design can be precisely anchored.

We break down the building into optimised and regular tessellated subareas, thereby creating the foundation for the organisation of the repeated process. This tiling of the architecture creates the groundword for simple modular building data models.


  • Precise mathemtical description of the architectural form
  • Minimise tessellations
  • Project coordinate system
  • Facade simplification
  • Calculation of floor area by use in accordance with DIN 277 or SIA
  • Rentable floor area

We modularise buildings

We arrange achitectural designs into modules and develop these into system-integrated building blocks.

The programmed shape and the tiled areas are combined to create the integration platform for a new type of interdisciplinary collaboration.

This platform facilitates a clash-free interaction of utility services and, most notably, an all encompassing and contiuous process that follows through planning, construction and operation of a project.

The result of interdisciplinary cooperation are integrated system building blocks for structure, facade, fit-out, utilities and operation. These facilities are managed in a database, where they can be transferred into further processes such as the bidding phase, prefabrication, logistics, assembly and occupancy.

digitales bauen moderates these interdisciplinary processes and models the information from involved planners and contractors into module plans and datasheets.


  • Integrated system building blocks for buildings or individual facilities (superstructure, facada, fit-out, utilities and operation)
  • Database rather than CAD as primary tool
  • Modular BIM server rather than conventional building data model

We configure buildings

We generate the architecture with project-specific building blocks and parameters.

With the office layout configurator, room modules can be positioned in the floor plan by the user themselves, based on programmed parameters. Bound by the parameters and data in the room modules, the configurator then generates a layout plan of all utilites, along with the associated material unit list of all fit-out and technical components.

By modularising the rooms and technical utilities, the final phase of fit-out and furnishing the building can be smoothly integrated and altered up until shortly before installation.

We prefabricate buildings

Prefabrication and logistics of the digitales bauen fully integrated building components are facilitated with database-supported software tools and CAD/CAM fabrication.
Prefabrication enables us to accelerate the construction process by up to 40%, with an overall better quality.

We prefabricate:

  • Ceiling-mounted duct routes
  • Utility Shafts
  • Bathroom Cells



Reduce complexity

Compared to conventional planning, modular planning can reduce the complexity of a project by up to 80%.


Reduce costs

With modular planning we reduce the overall costs by up to 20% compared to conventional planning.


Reduce amount of BIM data

Compared to conventional BIM, the amount of data in modular BIM is reduced by a factor of 20.


Shorten construction time

With prefabrication we can shorten construction time up to 40%.

About us

The company digitales bauen was founded in 1998 with the aim of transferring experience and results from many years of research at the Institute for Industrial Building Production at the University of Karlsruhe into practice.
From this context, a planning methodology was developed which systematically breaks down individual architectural designs and technical building concepts into modules and comprehensively integrates and details them according to industrial products.
For more than 20 years now, the methodology has been verified and continuously refined in a multitude of projects in the fields of housing, administration and industry.
Since 01.01.20, the planning and consulting company Drees & Sommer SE with headquarters in Stuttgart has held a 74.9 percent stake in digitales bauen. The common vision: to penetrate the construction industry step by step with a systematic, modular approach and to establish a digital process chain.
