In the East End of London in 2002, Lenkiewicz founded T1+2 Art Space which he directed and curated as an independent artist run project for six years.

[5] Lenkiewicz’s works have since then been exhibited internationally, including Tate Britain and All Visual Arts in London, Palais des Beaux-Arts in Lille, as well as in Dublin, Hamburg, Berlin and Venice.

Lenkiewicz's works primarily deal with the appropriation of language and mythology[6] by juxtaposing elements such as religious figures, pop culture icons, literary characters and motifs.

[7] Lenkiewicz's drawings and paintings often reference iconic imageries, including those by Albrecht Dürer, Pablo Picasso, Andy Warhol, and Hieronymus Bosch.

His most recent solo exhibition, The School of Night, was held at the Saatchi Gallery in 2018, featuring several paintings and drawings, with the highlight being a vast 9 x 4 metre canvas.
