DAHLIA | Bookcase is an open freestanding ash shelving unit.The product comes disassembled in 1 box and includes all metal fixing.Easy to assemble.Dahlia Collection is inspired by drain pipes and architectural lines the designer saw while living in London.While drain pipes are generally unassuming and uninspiring, Mueller noticed that the drain pipes on certain structures in London were sometimes a contrasting color, giving the structures themselves a sort of outline and added visual interest overall.Mueller replicated this theme with the Dahlia Collection by cutting away the edges of his products (a carpentry term called chamfering).The result is a revealing of untreated ash, which gives each product an outline effect against the stained black frames.
