Harris Westminster Sixth Form, Concrete seating- Part1
Terrazzo is a composite material originally invented by Venetian construction workers as a low cost flooring material, using marble chips from demolished buildings. The finished terrazzo surface exposes the marble chips and other fine aggregates, offering a striking surface of speckled shapes and colours.
We worked with students to design and cast their own terrazzo seating specifically for their art department, introducing them to the material’s history and its benefits as a partially recycled product. The students were challenged to navigate through the design process from conception to realisation, with guidance from tutors in problem solving techniques and instruction in various making skills.
Four groups of students each chose a site in the art department to situate their design. They began by analysing their site, including light conditions, circulation and function. They were given an introduction to relevant examples of site-specific architecture and design for inspiration.
Students began by making mock-up designs on paper and 1:1 card models before beginning the mould making process that would hold the concrete.
By the end of the day each group had made their mould and cast their concrete form, leaving it to cure for a week.
We will be returning for PART 2 of the workshop to release the moulds and grind back the concrete to reveal the terrazzo finish before installing the seating in the art department.
