About Transformbau
Transformbau is Erik Erdmann's carpentry and restoration workshop in Berlin-Treptow.
Carpentry and restoration
The workshop does two things that usually sit apart. One is fitted carpentry: wardrobes, storage, kitchens, workspaces, made to the measurements of a particular room. The other is restoration: historic windows and doors repaired rather than replaced, and reproductions built to match a set where one piece is missing.
The combination matters in Berlin, where most flats are older than the furniture that has to go into them. A room in an Altbau has walls that lean, floors that fall away and openings that are no longer square. Knowing how those buildings were put together is the difference between a piece that fits and one that has a gap down one side.

Materials, energy and repair
The timber comes from sustainably managed forests, and from regional sources where they are available. The workshop's electricity is 100% renewable, supplied by the cooperative Green Planet Energy. Heating comes from the offcuts the work produces anyway. And restoring a piece of furniture or a building element instead of replacing it adds decades to its life and saves the material outright. Where a historic door or window can be repaired, repairing it is usually both the cheaper and the longer-lasting option.
“There's no such thing as 'can't be done'.”
