Green Roof Case Study

Crystal Mozart

Size: 
25m² - 150m²
Duration: 
2 weeks
Client background: 

When well-known cruise company, Crystal, wanted its newest addition to its River fleet to reflect the journey it would take along the Danube River, it turned to ANS Global for its green roof products. Working with AD Associates, Crystal and ANS Global worked together on the designs and opted for a bespoke green roof terrace – the first of its kind amongst ANS Global’s customers.

Crystal has a long-term relationship with ANS Global, having worked on many other projects in the past. Its latest vessel is a barge, called Mozart, which travels from Austria through Switzerland and Germany. 

Steve McIntyre, Business Development Manager at ANS Global commented on the project, saying, “We wanted to design a terrace to reflect the journey the passengers would be taking. By incorporating species of alpine plants, those aboard Mozart will have the chance to walk on the terrace and identify the species and learn about their surrounding environment. This gives them a heightened cultural experience of the cruise and sets Crystal apart from its competitors.”

Adding to this, Nicola Preece of AD Associates said, “Working with Crystal was a great experience. We worked together alongside ANS Global to develop the first green roof terrace in the river cruise industry. The result is a unique, undulating roof terrace surface with a natural feel."

Scope of works: 

Alexandra Don is Crystal’s Vice President of Hotel Services and Design, and leads all design projects for vessels. On the Mozart project, she oversaw ANS Global’s work and provided direction in developing and delivering Crystal’s vision of a living garden aboard. During the journey there will be lots of confined water, such as canals, so Alexandra wanted to make use of the wide deck with a roof terrace to ensure guests had somewhere to relax and enjoy the outdoors. 

Works for the green roof terrace took only three days to complete – thanks to the modular design of ANS Grufekit green roof models. The roof is made up of multiple individual modules, each containing everything needed from a water reservoir and drainage layer to the soil and vegetation. The GrufeTiles clip together to make the system lightweight and simple to install. For this project, Grufekit was used as the base of the roof terrace and then landscaping works took place to create the undulating surface. To finish, ANS Global planted alpine species of plants.  

Originally a smaller riverboat, the vessel was stripped and then built back up to offer more spacious suites and offer a contemporary design. Now sailing as Crystal Mozart and at almost double the width, 154 passengers are able to enjoy the sights along the Danube River between Germany, Austria, Switzerland and Hungary.

We have worked with ANS Global on previous projects, such as Crystal Serenity and Crystal Symphony. Incorporating greenery on Mozart therefore continues this tradition that began on our ocean ships. Now for our river cruise ships, passengers have a space to unwind that complements the sights they will see along the Danube River. The plant life naturally adapts to the seasons, so I’m especially looking forward to seeing it in the spring when everything comes back into bloom.
