Work triangle: sink to hob to fridge. Total perimeter 4–7 m. Open-plan is the default for new Irish self-builds.

Work triangle: sink, hob, fridge. Total perimeter 4–7 m. Each leg 1.2–2.7 m. No obstruction between them. Open-plan is the default for new Irish self-builds: kitchen, dining, living in one space. Easier for family life; harder to keep clean (cooking smells, noise). Zones: prep (sink), cook (hob), store (fridge, pantry), serve (worktop, dining). Each zone needs 1.0–1.5 m of worktop. Most Irish self-builds use an L-shape or a U-shape with a peninsula, opening onto the dining and living areas. A separate utility room (for the washing machine, dryer, and second sink) keeps the noise and mess out of the main kitchen.

TL;DR

  • Work triangle: sink, hob, fridge. Total perimeter 4–7 m. Each leg 1.2–2.7 m. No obstruction between them.

  • Open-plan is the default for new Irish self-builds: kitchen, dining, living in one space. Easier for family life; harder to keep clean.

  • Zones: prep (sink), cook (hob), store (fridge, pantry), serve (worktop, dining). Each zone needs 1.0–1.5 m of worktop.
