SKULL studio turns car park into play lot with installation ‘the floor is lava soft!’ in estonia

skull studio says ‘The Floor is lava soft’

At the 2025 UIT Festival in Tartu, Estonia, SKULL studio unveiled ‘The Floor is lava soft!’ — a temporary installation that turns a car park into an unexpected playground. Led by Czech artist Matěj Hájek, creative strategist Pavel Krajčík, and photographer Bet Orten, the collective replaces asphalt and parked cars with straw bales to soften the urban landscape. The result is a curious intervention that invites passersby to touch, jump, play, sit, gather, or simply pause, blurring the boundaries between everyday infrastructure and spaces of play. Sometimes all it takes is to simply create spaces where play is allowed.

skull turns the city into a canvas of play

Founded in 2020 by Matěj Hájek and Bet Orten, SKULL studio positions itself as a laboratory of ideas, concepts, and visions. Sculpture becomes a gaming element, the landscape transforms into a playground, interiors evolve into works of art, and photography transcends into image-making. Multidisciplinarity lies at the heart of the practice, uniting expertise from art, design, and technology into interventions that are both playful and socially engaging.

With ‘The Floor is lava soft!’, the studio demonstrates its ethos in action: challenging the rigidity of the urban environment with an intervention that is ephemeral, humorous, and human. In doing so, SKULL turns the city itself into a canvas, one where softness interrupts hardness, and where play transforms everyday life.
