Galley or L-shape (2400-3000mm). Two-burner cooktop, 450mm dishwasher, bar fridge. Overhead storage to ceiling. Fold-down dining table.

Questions Homeowners Usually Ask Next

How much should I budget for a kitchen renovation in Melbourne?

Budget depends on layout changes, cabinetry level, benchtop choice, appliance scope and trade complexity. As a rule, fixed-layout refreshes sit much lower than structural redesigns with new services and premium finishes.

Should I keep the same kitchen layout to control cost?

Usually yes. Retaining the sink, cooktop and major service points helps contain demolition, plumbing and electrical costs. Layout changes only make sense when workflow, storage or family use will materially improve.

What kitchen upgrades usually add the most practical value?

Better drawer storage, smarter appliance placement, durable benchtops, layered task lighting and a well-sized rangehood tend to improve daily use more than cosmetic-only upgrades.

How long does a kitchen renovation usually take?

Most kitchens run over several weeks rather than a few days, especially when cabinetry manufacturing, stone templating and multiple trade visits are involved. Lead times often matter more than the demolition phase.
