A musical instrument museum in Phoenix, Arizona, featuring a a fluid layout design, will be unveiled on 24 April 2010.

The $125m museum, which is touted as the first truly global museum of its kind, has been designed by Richard Varda and the US firm RSP.

The 190,000ft² facility will showcase the history and diversity of instruments and introduce guests to their varied and unique sounds.

The museum is equipped with 75,000ft² of gallery space, a two-storey structure featuring fractured stone forms.

A flowing river-form atrium links the interior galleries while the interior finishes mimic the Arizona landscape. Diffused daylight illuminates the galleries and public spaces through windows and skylights.

The scheme features a courtyard designed by landscape architectural firm Ten Eyck Landscape Architects.

The scheme’s first floor will include an orientation area, galleries, the hands-on experience room, a restaurant, a family centre, music shop, conservation lab, administrative offices, instrument storage and exhibition support space, while the second floor will have five galleries.

The building will have a rain-screen façade and will also feature a 300-seat performance hall, spanning the two floors.

The building has made use of few sustainable concepts which include the use of fly ash in the concrete, 25,000ft² of photovoltaic solar panels on the second-storey roof areas, a chemical-free chiller water system, and extensive xeriscaping.

The interior spaces have a 15mm polyethylene multicore vapour barrier placed between the sub-base and the slab-on-grade concrete to retain moisture and to protect the wooden antique instruments.
