How to Light an Open Plan Living Space: 10 Questions That Matter

Open plan kitchen, living, and dining is the dominant layout in Australian new builds. It creates flexibility and a sense of space — but it's genuinely difficult to light well. Most end up feeling either too bright (like a supermarket) or inadequately lit after dark. Here's how to avoid both.

1. Why is open plan living so hard to light?

Because it combines three or four different use zones in a single shared space, each with different lighting requirements. The kitchen needs bright task light for food preparation. The dining area needs focused, intimate light. The living room needs soft, flexible ambient light. Getting all three to coexist without conflict requires deliberate zoning.

2. What's the biggest mistake in open plan lighting?

A uniform grid of downlights across the entire ceiling. It's the default builder solution. It produces even, flat light everywhere — which means it creates no zones, no atmosphere, and no flexibility. The kitchen looks the same as the living room, and the dining table has nothing to anchor it. You end up eating dinner under the same light you use to find your keys in the morning.

3. How do you create zones in an open plan space?

Through a combination of fitting placement, circuit separation, and fixture type. A pendant or pair of pendants over the dining table immediately defines that zone. Under-cabinet strips in the kitchen separate the task area from the ambient space. A floor lamp or wall sconce in the living zone creates a separate layer that can be used without activating the overhead lights at all.

4. How many circuits should an open plan space have?

At minimum, three — one for kitchen task and ambient light, one for dining, and one for living. Ideally more. Under-cabinet strips should be on their own switch. A feature pendant over the island should be independently controlled. The more independently controllable the circuits, the more flexible the space. This is specified in the lighting plan, not worked out on the day.

5. Should the kitchen area be brighter than the living area?

Yes, for task purposes. A kitchen bench needs roughly 300-500 lux for comfortable food preparation. A living room needs around 100-150 lux for ambient comfort. The contrast between zones is what makes an open plan space feel considered. If everything is lit to the same level, the space has no hierarchy and no sense of where you're supposed to be.

6. What role does the island bench play in lighting an open plan space?

A large island is often the visual centre of an open plan space. Pendant lighting above it serves both a task function (light for prep work) and a visual anchoring function — it defines the kitchen zone and creates a focal point. Getting the pendant height right matters: too high and it feels disconnected, too low and it obstructs sightlines. Around 800-900mm above the bench surface is a reasonable guide, depending on the fitting.

7. How do you handle lighting when the open plan connects to an outdoor area?

Coordinate the colour temperatures. If your interior is at 2700K and your alfresco is at 4000K cool white, the visual break when you look through the glass doors is jarring. Matching or harmonising colour temperatures across the indoor/outdoor connection creates a seamless extension of space — which is the whole point of that design.

8. Does furniture position need to be known before the lighting plan is done?

Yes, to the extent possible. The dining pendant should sit above the centre of the dining table — which means you need to know where the table will be. Downlights in the living area should be offset from where people will be seated to avoid glare. If you don't know your furniture layout yet, the lighting designer works with assumptions and documents them so adjustments can be made if the plan changes.

9. What lighting works well near a fireplace or feature wall?

Directional accent lighting — either a recessed adjustable spotlight or a wall-mounted picture light — draws attention to the feature without flooding the surrounding space with light. A fireplace already produces warm, dynamic light; the lighting design around it should complement rather than compete. Keep the colour temperature of any fittings near a fire at 2700K to stay coherent.

10. Can a good lighting plan transform an open plan space?

Demonstrably yes. The difference between a builder's default electrical plan and a designed lighting plan in an open plan space is felt every single day — in how the morning feels, how the kitchen functions during meal prep, how the evenings settle. It's not a luxury finish. It's how the space was supposed to work. At Lumen & Line Designs, open plan lighting is one of our core specialities.
