A kitchen that runs well is one where nobody has to walk backwards. That sounds trivial and it is the whole of good kitchen planning.

The one-way principle

Material should move in one direction: goods in, storage, preparation, cooking, plating, service. Dirty items return on a separate route to wash-up, and waste leaves without re-entering production.

Where a kitchen forces staff to backtrack, you get collisions, contamination risk and lost time on every single cover.

Clearances that actually work

These are working minimums, not ideals.

Utilities before finishes

Gas, water, drainage and electrical positions must be fixed before floors are laid and walls are tiled. Retrofitting a drain into a finished floor costs many times what it costs to place it correctly at first pour.

  • Gas points: position and connected load per appliance
  • Electrical: rating, phase and whether the point is switched locally
  • Water: hot and cold, with the pressure the appliance actually requires
  • Drainage: trapped gullies with a stated fall, positioned under wash-up equipment
  • Exhaust: duct route, size and the make-up air path

Ventilation is not optional

Extraction removes heat, grease and steam. Make-up air replaces what is extracted. A kitchen with extraction and no make-up air goes negative, doors become hard to open, and extraction efficiency collapses.

Size the hood to overhang the equipment on all open sides, and size the fan against the heat load rather than against the hood area alone.

Plan for cleaning

Equipment on adjustable feet with a clear floor gap can be cleaned under. Equipment sitting on the floor cannot. Coved corners can be wiped out; square welded corners collect residue. These details decide whether a kitchen stays hygienic under pressure.

Frequently asked questions

Feet for anything connected to a fixed utility, castors for anything that must be moved for cleaning or service. Adjustable feet also absorb floor level variance, which is present on nearly every site.
