We „trim fit“ your building for the future.

We evaluate the building’s condition and, if needed, strengthen the elements to be preserved. Energy-saving measures play an important role in our decision process.

We are able to reduce the heat requirements of your building by applying insulation and isolation measures that will increase the comfort level. Plumbing, electrical, heat and sanitary installation work are part of our portfolio as well as the rebuilding and extension of roofs, staircases, floors, windows or inside and outside walls.

We offer our services especially for:

  • Objects classified as historical or protected
  • Office and business buildings
  • One or multiple family homes
