Island Kitchens in London

A run of cabinetry on the wall and a freestanding island in front of it, with prep space on the kitchen side and seating on the room side. The layout for an open-plan room with the floor to walk round it.

Island kitchen · In plan

The island kitchen, in plan

The wall run carries the services: sink under the window, dishwasher beside it, hob with worktop either side, and the fridge and the oven tower together at one end. The island stands in front of it, 2.4 metres long and a metre deep with the seating overhang, and the space around it is what sets the room. A metre of clear floor on every walked side is the least; 1.2 metres between the run and the island where dishwasher and oven doors open into the gap. That makes a room 3.6 metres wide the absolute minimum and 4.2 metres comfortable.

Island kitchen · What to get right

Getting an island kitchen right

Six things a designer checks before an island kitchen is drawn.

01

The room, not the island

An island is sized by the floor around it. A metre on every walked side, 1.2 metres where the dishwasher and the oven open into the gap. Below that, a peninsula gives most of the benefit.

02

Island size

Nine hundred to a thousand deep, 1.8 to 3.0 metres long. Longer than 3.0 metres and the walk round it undoes the point; deeper than a metre and the far side cannot be reached.

03

What it carries

Prep worktop, pan drawers and seating as standard. A hob needs a downdraught or a ceiling hood; a sink needs a drain under the floor; both are decided before the floor goes down.

04

Services under the floor

Power for sockets in the island end is the least it needs; a hob needs a supply, a sink needs a drain. In a ground-floor extension these go in the slab, so the island is drawn before the builder pours it.

05

Tall units together

Fridge and oven tower at one end of the wall run, so the worktop between them and the sink is unbroken and the island faces a run of worktop rather than a wall of doors.

06

Lit from above

Pendants or downlights over the island on their own dimmer, LED under the wall units for the run. The island is the one part of a kitchen lit from the ceiling.

Island kitchen · Where everything goes

The wall run and the island

The wall run and the island share one worktop height, 910mm, so the two read as one kitchen. On the kitchen side the island is drawers, deep ones for pans and shallow ones for tools, with a bin pull-out near the sink end. On the room side the worktop overhangs 300mm for three stools and the panel below is finished as furniture. Where the hob goes on the island, a downdraught extractor keeps the ceiling clear; where it stays on the wall, the island is pure prep and the pendants over it are for the people.

Island kitchen · Planning

Planning an island kitchen

Five decisions, in the order your designer makes them.

01
Start with the island
Draw the island and its walkways first; the wall runs fit the floor that leaves. An island planned last is always too big.
02
Fix the services
Power at least; a supply for a hob or a drain for a sink if the island carries either. These go in the floor before it is laid.
03
Decide the hob
On the wall with a hood, or on the island with a downdraught. On the wall keeps the ceiling clear and the island social; on the island puts the cook facing the room.
04
Size the seating
Three stools per 2.4 metres on the room side, 300mm overhang, stools at 650mm. The room side is the front of the kitchen and is finished as such.
05
Light it twice
Pendants over the island for the people, LED under the wall units for the cook, on separate dimmers, so the island can be lit when the kitchen is not.

Island kitchen · Built

The island, built

The Kensington is a pale sage handleless island kitchen: a wall run under roof lights, and a quartz-topped island with a breakfast bar, a lit plinth and pan drawers on the kitchen side. The Belgravia is the same layout in matt black, with a range cooker and a lit marble splashback on the wall and a large island with seating for three in front of it.

Both are single wall runs with an island, which is the island layout in its simplest form. Where the wall run turns a corner it becomes an L with an island; where a third wall is used it is a U with an island in the middle. And where the width is not there, the island joins the wall at one end and becomes a peninsula.

“Great service, quick, reliable, and beautiful finish! Would highly recommend metro for all your joinery needs.”

Miriam | Rosella InteriorsGoogle review

“I was very pleased with my wardrobe fitted by Metro. By having a custom design I could have exactly the spacing and layout I wanted. They came out to me so we could match the colour to my existing inbuilt wardrobe. Any changes I wanted in the design Mike was quick to do and send me updated previews. It also came in considerably cheaper than a well known wardrobes brand. A couple of snagging issues as you'd expect, and other than some mild chasing I had to do they put it right and all was good. I'd happily recommend them.”

Sebastian HaffGoogle review

“I'm delighted with the new metro fitted wardrobes, the bedroom is completely transformed. Very stylish, high quality finish. Very impressed with the service from first enquiry through to final installation. I would highly recommend. Thanks to Mike who designed the wardrobe, Palak for excellent customer service and special Thanks to Pappu Patel and his team for converting the design into practicality.”

Island kitchen · FAQ

Questions about the island layout.

At least a metre of clear floor on every side you walk around, and 1.2 metres between the island and the wall run where a dishwasher or an oven door opens into the gap. For a modest island that means a room about 3.6 metres wide as an absolute minimum and closer to 4.2 metres to be comfortable. Below that, a peninsula gives most of the benefit without the pinch points.

Between 1.8 and 3.0 metres long and 900 to 1000mm deep, including a 300mm overhang for seating. Shorter than 1.8 metres it is a table; longer than 3.0 metres the walk around it undoes the reason for having it; deeper than a metre the middle of the top cannot be reached from either side. A 2.4-metre island seats three and gives a metre and a half of prep space.

On the wall, unless the cook wants to face the room while cooking. A hob on the island needs a downdraught extractor in the worktop or a ceiling hood over it, and a gas or electric supply under the floor; it also puts heat and splashes where people sit. A hob on the wall with a hood keeps the island as prep space and seating, which is what most families use it for.

Yes, if a drain can be run under the floor with enough fall to reach the soil pipe, which in a ground-floor extension means deciding before the slab is poured. A sink on the island puts the cook facing the room while they wash and prepare, which is why it is popular; the cost is a wall run without a sink, and a dishwasher that has to go on the island too.

Power at the very least: sockets in the end panel or a pop-up in the top. A hob needs its supply, a sink needs water and a drain, and both run under the floor to the wall. In a new extension we give the builder the island position and its services before the floor goes down; in an existing room the floor is lifted along one route, which is why island services are decided at the design visit.

Three at a 2.4-metre island, four at 3.0 metres, allowing 600mm per person. The overhang on the room side needs to be 300mm at worktop height for knees, with the stools at 650mm for a 910mm top. Seating goes on the room side only; the kitchen side is drawers and prep space, and the two are separated by the worktop itself.

The island adds a freestanding piece of cabinetry finished on all four sides, its worktop, and services under the floor, so an island layout costs more than the same wall run alone. Our island kitchens start from £8,900 for the cabinetry, delivered and fitted, with most between £8,900 and £12,600. Prices include VAT, delivery and installation by our own fitters; worktops, appliances, sink and tap are quoted separately. A design visit gives you a fixed written price for your room.
