About us

Auktionshaus am See

The Auktionshaus am See is located in Constance, close to the shore of Lake Constance, at Beethovenstraße 1b in the Musicians’ Quarter (Musikerviertel). We specialise in all-in-one solutions for estates, liquidations and insolvencies, as well as in entire collections. We are also happy to include individual items in our auctions. Our staff draw upon many years of extensive experience in the international auction business. You can rely on our integrity, discretion, reliability and competence.


We are happy to manage the estimation and auction of your valuables:

jewellery, wristwatches and pocket watches, silver, coins and medals, paintings, graphics, sculptures, stamps, militaria, historical items, glass, porcelain, Asian items, African items, miscellanies, antique toys, luxury and design objects, furniture, furnishings, lamps, carpets, and much more.

The manager wears red gloves and inspects the delivered goods - in this case paintings.


We take our social responsibility as business owners very seriously. We bear the responsibility towards society and the environment above all else. For us, this includes employing workers with good conditions, recycling materials such as packaging and, of course, selling timeless products instead of short-lived trends. As conscious consumers, we promote the reduction of CO2 emissions and waste. Sustainable investments instead of a throwaway mentality: Antiques are green! Buying antiques means investing in individuality, style and sustainability.

Online auctions

Auktionshaus am See focuses strongly on online auctions. We auction your objects through the four largest auction platforms in the world. We compile our catalogues in English and German.

We look forward to your enquiry and are committed to serving you well.
