Keith Simpson is a British sculptor known for his intricate aluminium wire trees which explore the relationship between natural growth and structural form. Originally from rural Berkshire and now based in Cambridge, Simpson trained as a civil engineer before turning to sculpture, bringing a strong understanding of balance and construction into his work.

After working across materials such as clay, wood and stone, he began experimenting with wire in 2005. What started as an alternative approach to figurative sculpture developed into a sustained exploration of tree forms, which have become central to his practice.

Each piece is made entirely by hand from a continuous length of aluminium wire, built through a highly controlled yet intuitive process. Larger works can incorporate significant lengths of wire and thousands of individually formed leaves, resulting in structures that are both delicate and complex.

Simpson’s sculptures are characterised by their precision and lightness, capturing the rhythm and irregularity of natural tree forms while maintaining a strong sense of balance. Often presented within circular frames or on simple bases, the works suggest growth held within a defined structure, bringing together organic movement and formal clarity.

His work has been exhibited widely across the UK and is held in private collections.
