Summer 2026

The June/July/August 2026 edition of AZURE is dedicated to our 16th annual AZ Awards — and also features the best of Milan, the New Museum’s expansion, the latest in building envelope systems and more!

The AZ Awards issue packs much more than our winners and finalists — though they certainly take pride of place. (And you can read all about them on our dedicated AZ Awards site.)

A public space for daydreaming – Austrian firm Heri & Salli builds a second Flederhaus in the Flugheld Aspern district.

Imagine a public building without a facade, one that invites you to scale its many levels before choosing a hammock to doze away on and enjoy the last days of summer. In Vienna, Heri & Salli has created just that – and it’s the second time they’ve done so. Their new Flederhaus (or “bat house”) is a prefab structure with a gabled roof located in Flugheld Aspern, a district on the outskirts of Vienna that is currently being developed for residential use. The open-air structure rises like a playful symbol, its five levels kitted out with 32 hammocks. It invites locals to walk right in, and lie down while taking in a full panorama of their surroundings.

The first hammock house the firm created was in 2011, in the city’s Museumsquartier. The firm, led by Heribert Wolfmayr and Josef Saller, has been working in architecture for 10 years now, and Flederhaus encapsulates its experimental energy. Describing Flederhaus, the firm explains, “It becomes the enlarged public open space of a vertical structured sphere. It’s a constructed public space with additional value, an oasis for the soul. Staying in a public area is only temporary…a kind of sequence, we give this sequence a permanent setting.”
