Designing Open Plan Kitchen Dining Living Room Layouts in Australia
Open plan living has become increasingly popular in Australia, with homeowners embracing the seamless flow between kitchen, dining, and living spaces. However, determining the right dimensions for these multifunctional areas can be a challenge. This guide will help you navigate the intricacies of open plan kitchen dining living room dimensions, ensuring your space is functional, comfortable, and stylish.
Understanding Open Plan Living Dimensions
Before diving into specific dimensions, it's crucial to understand the principles of open plan living. These spaces should be fluid, allowing for easy movement and interaction between zones. They should also be well-proportioned to accommodate furniture and activities comfortably.
Key Considerations for Open Plan Dimensions
- Room Size: The total square footage of your open plan space will dictate the size and number of zones you can include.
- Furniture Scale: The size of your furniture should be proportional to the room. Oversized furniture in a small space can make it feel cramped, while undersized furniture in a large space can look lost.
- Traffic Flow: Consider how you and your family will move through the space. There should be clear paths between zones, with no obstructions.
- Zoning: While open plan, these spaces should still feel distinct. Using furniture, lighting, and flooring to define zones can help achieve this.
Kitchen Dimensions in Open Plan Layouts
The kitchen is often the heart of the home, so it's crucial to get the dimensions right. In open plan layouts, the kitchen typically takes up around 30-40% of the total space. Here are some key dimensions to consider:

| Kitchen Feature | Minimum Dimensions (mm) | Ideal Dimensions (mm) |
|---|---|---|
| Kitchen Island | 900 | 1200-1500 |
| Work Triangle (distance between cooktop, sink, and fridge) | 1500-2700 | 2100-2700 |
| Cupboard Depth | 300 | 600 |
Dining Area Dimensions
The dining area should be large enough to accommodate a table and chairs comfortably. It typically takes up around 20-30% of the total open plan space. Here are some dining table dimensions to consider:
| Dining Table Size | Seating Capacity | Minimum Dimensions (mm) |
|---|---|---|
| Breakfast Table | 2-4 | 700-900 (L) x 600-900 (W) |
| Standard Dining Table | 4-6 | 900-1200 (L) x 900-1200 (W) |
| Large Dining Table | 6-8 | 1200-1500 (L) x 900-1200 (W) |
Living Room Dimensions
The living room should take up the remaining 40-50% of the open plan space. Here are some key dimensions to consider:
- Sofa Size: The length of your sofa should be no more than 75% of the room's length to allow for easy movement around it.
- Coffee Table Size: The coffee table should be around two-thirds the length of your sofa to create balance.
- Seating Arrangement: Aim for a seating arrangement that encourages conversation, such as a U-shape or an L-shape with a sofa and two armchairs.
Maximising Space in Open Plan Layouts
To make the most of your open plan space, consider the following tips:

- Use multi-functional furniture, such as a sofa bed or a dining table that can extend to accommodate more guests.
- Install floor-to-ceiling shelving to maximise vertical space.
- Consider built-in furniture, such as a banquette in the dining area or a desk in the living room, to save space.
- Use area rugs to define zones and add warmth to hard floors.
Remember, the key to successful open plan living is balance. Your space should be functional, comfortable, and reflect your personal style. By considering these dimensions and principles, you can create an open plan kitchen dining living room that works for you and your family.
