I'm Darren O'Neill, a designer and maker specialising in SketchUp Pro and SketchUp Layout for bespoke cabinetry and fitted furniture. My work is centred on model-led workflows, where accurate 3D models form the single source for production, installation, and CNC preparation.
With a background in architecture and product design education, I place strong emphasis on clarity, organisation, and buildability. Models are structured using components, tags, and consistent conventions to support efficient drawing output and reliable manufacture.
Through Koa Design (est. 2020), I work on bespoke projects where drawings need to translate cleanly from screen to workshop, ensuring consistency from design intent through to final installation.
Clean, structured 3D models for bespoke furniture, cabinetry and fitted interiors. Useful for client approval, design development and checking proportions before manufacture.
SketchUp Modelling & Client Visuals

Clear model-led drawings for manufacture, including component layouts, assembly views and installation information. Built to help ideas move smoothly from screen to workshop.
Production Drawings & Workshop Packs

CNC-ready component preparation, sheet nesting and toolpath planning for plywood and panel-based furniture. Designed to improve accuracy, reduce waste and make production more efficient.
