The Transformatorhuis (Trafo House) is an iconic space with an unusual wooden roof construction and high, narrow windows. The Transformatorhuis is ideal for a nightclub-type interior, with lounge sofas or long tables set for a dinner in style.

Venue Trafo House

The Transformatorhuis (Trafo House) is well suited to a night-club style interior with lounge sofas or an atmospheric dining space with long set tables. Speakers at international conferences appear here before audiences of around 500.

Building history

In 1904, this building housed a plant producing carburetted water gas. The Amsterdam energy company later used it as a transformer workshop.


Making the factory buildings more sustainable is more complicated than with newer buildings as the possibilities are more limited and costly thanks to the buildings’ listed status. In the Transformatorhuis, investments have been made in LED lighting. The switch to LED light has resulted in a 65% reduction in electricity use. Gas consumption fell by 28% thanks to roof and window insulation.
