The Best Floor Plans for Family Living in Western Sydney

A floor plan is the most important decision in a new build, and the hardest to undo. We have seen families spend years working around layout decisions made in a sales office in 30 minutes. Here is how to think about the spaces that matter for raising a family in Western Sydney.

The kitchen-dining-living open plan

This is the heart of every modern Australian home. Get the proportions right and the rest of the house feels supported. Get it wrong and the family lives elbow-to-elbow in a kitchen that does not work.

• Minimum width: 5 metres for an island kitchen with dining beside it.
• Minimum length: 9 metres front to back to comfortably fit kitchen, dining, and living areas.
• Ideal: 6m wide x 11m long, giving 66 sqm of open-plan space.
• Ceiling height: 2700mm to 2900mm. Below 2400mm in a large open plan feels oppressive.

Kitchen layouts that work

• Island with butler pantry behind: Hides the working kitchen, keeps the island clean for socialising. Best layout for entertaining families.
• L-shaped with island: Standard, good for medium kitchens.
• Galley with island: Long and efficient, suits narrower blocks.
• U-shaped with island: Maximises bench space but can feel enclosed.

Island length minimum: 2400mm for two bar stools. Better: 3000mm for three. Counter overhang: 300mm for seating.

Bedroom layout

For a 4-bedroom family home:

• Master suite: 14 to 18 sqm, with walk-in robe and ensuite. Set away from children’s wing where possible.
• Children’s bedrooms: minimum 3m x 3m. 3.2m x 3.5m is more comfortable. Built-in robes essential.
• Avoid putting a bedroom directly off the kitchen-living open plan. Sound travels.
• Consider a guest bedroom or convertible study near the entry for visiting family or future flexibility.

The second living space

Families with school-age children consistently report that the most valuable space in their home is a second living area away from the main kitchen-living. Options:

• Media room: Acoustic-treated, dimmable lighting, ideal for movies and gaming. Usually 4m x 5m.
• Rumpus / kids’ lounge: Upstairs in double storey homes. Lets kids play with friends without taking over the main living. 4m x 5m or larger.
• Open study / library: A second living that doubles as a workspace.

Skipping the second living to save $30,000 to $50,000 at build is the single most regretted floor plan decision we hear from families 5 years later.

Bathrooms

• Master ensuite: double vanity, shower, separate toilet preferred.
• Family bathroom: bathtub plus separate shower in a 3-piece bathroom is gold for families with young children.
• Powder room near the entry for guests.
• Downstairs powder + family bath upstairs is the common pattern in double-storey.

Storage

• Walk-in pantry, not just a wall pantry.
• Linen press in the hallway, plus separate towel storage in each bathroom.
• Mud room or drop zone at the garage entry for shoes, bags and coats.
• Built-in robes in every bedroom.
• Garage storage built in, not an afterthought.
• Roof or basement storage where the design allows.

Outdoor connection

• Alfresco directly off the kitchen-living open plan, under the main roof.
• Wide sliding stacker doors (3m+ openings) to merge inside and outside.
• Outdoor kitchen for properties with outdoor entertaining focus.
• Sight line from kitchen to a backyard play area for parents of young children.

Common floor plan mistakes

• Master bedroom directly above the children’s bedrooms (footsteps audible).
• Laundry off the kitchen with no separation (smell and noise mix with cooking).
• Single bathroom for a 4-bedroom home (mornings become chaos).
• Awkward L-shaped open plan that creates a corridor through the kitchen.
• Stairwell that comes up into the master bedroom area (privacy issue with guests).
• Garage door visible from the main living area (loses some elegance).
• Long entry corridor with no natural light.
