What is involved in islands?
Kitchen islands are the single biggest aesthetic and functional change in any kitchen renovation. They convert a galley kitchen into a social space, provide prep area away from the wall, and often serve as the morning coffee / kids' homework station that the dining table cannot.
The island is the kitchen design decision that affects every other decision. Cabinetry layout flows around it. Walkways are dictated by it. The cooktop and sink positions depend on whether they are on the island or on the wall. Most network designers start with the island during the initial design appointment.
Minimum dimensions matter. Walkways around an island should be at least 1.0m wide (1.2m if multiple cooks). The island itself needs at least 600mm depth for prep, 900mm preferred. A seating overhang adds 300-400mm to the island depth. So a fully-functional island with seating is about 1.2-1.3m deep, requiring a kitchen at least 4.5m deep total.
Integrated cooking on the island uses either an induction cooktop with downdraft extraction (compact, ceiling stays clean), a gas cooktop with a feature pendant rangehood (premium look, expensive install at $3,500-$8,000 for the ceiling-mount rangehood), or a wall-only cooktop layout (simplest, the island is prep-only).
Stone benchtop on the island is a signature feature. Most network renovators recommend matching the stone between island and perimeter benches for visual consistency, though some premium builds use a contrasting island stone (e.g. dark perimeter, white marble island) for drama.

Islands questions, answered.
How big does my kitchen need to be for an island?
Minimum 4m wide by 4.5m deep is workable for a small island (1.5m long, no seating). 4.5m wide by 5m deep is comfortable for a full-size island (2.4m long with seating for 3). Below these dimensions, an island restricts the walkway and is usually a poor choice. Network renovators measure and advise before quoting.
Should the island have a cooktop or just be a prep bench?
It depends on your priorities. A cooktop on the island means the cook faces the rest of the room while cooking (sociable) but the extraction is harder (downdraft is less powerful than overhead rangehood, ceiling rangehoods over an island are expensive and visible). A prep-bench-only island is simpler, faster to install, and frees up the wall for the cooktop and rangehood.
How much does a kitchen island cost in Adelaide?
A simple 1.8m modular prep island starts at $4,500 supplied and installed. A 2.4m island with stone benchtop, drawer banks, and seating overhang typically costs $9,000 to $14,000. A premium custom island with mitred stone waterfall ends, bespoke detailing, and integrated appliances runs $15,000 to $28,000.
What is a waterfall island?
A waterfall island has the benchtop running down to the floor at one or both ends, like a continuous slab. It is a premium look popular in Adelaide luxury kitchens. The technique requires mitring the stone (joining two pieces at 45 degrees so the seam disappears). Cost per waterfall end is typically $1,500 to $3,500 over a standard square-edge end.
