AK Water Features is a London-based practice that designs, supplies and installs bespoke water features for prime residential gardens and landscapes — working as the water feature specialist within landscape architects’ and garden designers’ project teams.

Led by Antti Koskelainen, the practice draws on his ten years as Senior Design Engineer at Studio Ewing, delivering complex water features for prime residential properties in London and internationally—from concept and detailed design through manufacture, installation and commissioning.

Antti has worked on the design and installation of water features for three BALI National Landscape Award-winning gardens, as well as RHS Chelsea Flower Show Gold Medal and Best in Show gardens. His work included personally leading a water feature design, project management and installation for a BALI Grand Award-winning garden.

Antti holds a BEng in Mechanical Engineering (Automotive) and brings more than a decade of experience in mechanical design and design for manufacture. Each feature is developed as a complete engineered system, resolving hydraulic performance, fabrication, installation and long-term maintenance alongside the visual intent.

AK Water Features provides design, supply, installation, and maintenance of water features, and takes responsibility for how they perform. The approach balances technical resolution with sensitivity to atmosphere, reflection and materiality, to bring out the magical qualities of water.
