In response to an international design competition for Lithuania’s National Concert Hall in Vilnius, Iranian architecture firm Mirage Architecture Studio designed a conceptual solar-powered venue sheathed in a double skin facade. Dubbed Tautos Namai, the cuboid building proposal houses art inside and out — the exterior transforms into a vibrant artwork at night with holographic displays. Per the competition’s brief for sustainability, the conceptual project would not only produce more energy than it uses but would also minimize site impact and be built of recycled materials.

In February 2019, the Vilnius City Municipality announced an international competition for a concert hall to be located on Tauras Hill, a popular park that offers a sweeping view of the city. To preserve the proportions of the old trade union palace and reflect the natural surroundings, Mirage Architecture Studio proposed a glass cube with a transparent outer shell and an opaline inner shell.

“One reflecting the outside, and the other reflecting the enigmatic atmosphere inside,” explained the architects of the facade. “These glasses are made of photovoltaic tiles and produce a wide range of solar energy. So, in addition to creating a sense of belonging in the unconscious of the audience, an inexpressive and semi-transparent state of truth within it appears in mind. And all of this happens on the daytime. But at night time, the project has another story to tell. The Lithuanian National Music House is shining like a diamond using more than 18,000 holographic display; thus, the building’s appearance will never be reiterative at night, displaying a variety of surreal and abstract images.”

The multifunctional, 550-capacity concert hall would be tucked underground, while the above-ground spaces could be used for artist workshops, training venues and other purposes. To reduce environmental impact, structural materials would be recycled from the previous building on site, site impact would be minimized wherever possible and recycled natural materials would be used for acoustic padding on the walls of the hall. Mirage Architecture’s submission did not win the competition; Spanish architecture firm Arquivo was recently announced the winner. Still, the design is an innovative way to combine solar power and art under one roof.
