Sustainability is in our DNA

Sustainability is in our DNA

The company W. Schmid & Co. Kommanditgesellschaft AG was established by Walter Schmid in Glattbrugg in 1966. Initially, the construction firm concentrated on road building and underground engineering. Gradually, however, the focus shifted towards above-ground structures, in particular apartment construction. When the company began not only taking care of the construction work but also doing the fit-out with painter and decorators, floorers and kitchen installers, the general contractor was born. It now offered everything from a single source, ready for occupation and at a fixed price.

Given its location in the immediate vicinity of the airport, many of W. Schmid AG’s orders and customers came the airport region around Kloten. Swissair was a regular customer, as were the local hotel chains with their airport hotels. These projects also formed the basis of the company’s first large-scale development activities. Underused car parks in the vicinity of the airport were transformed into hotels with an international flair and works yards became modern business centres. As you can see, our motto of “Seeing what will be” has been with us from the very start.

The topic of sustainability is also in the company’s DNA. It completed its first solar façade in 1988 and its first Minergie-certified apartment building in 1998. The final milestone was the world’s first energy-self-sufficient apartment building, which is completely independent of the electricity grid, supplying its own electricity via a photovoltaic façade. You can read more about this in the section on sustainability.

In 2012, the company founder then arranged for the business to be handed over to the next generation. This laid the foundations for the firm to continue operating as an owner-managed SME that always puts customer needs first.
