When you're planning a new kitchen, wardrobe or storage wall, one of the first decisions is whether to go custom or flat pack. Both have a place, and the right choice depends on your space, your budget and how long you want it to last.
Here's an honest comparison to help you decide.
What's the difference?
Flat pack cabinetry is mass produced in standard sizes, sold in boxes and assembled on site or by the homeowner. Widths usually come in set increments, and heights and depths are fixed.
Custom joinery is designed and made for a specific space. Every cabinet is sized to fit, and materials, finishes and hardware are chosen for the job.
Cost
Flat pack is cheaper up front, especially for simple runs of cabinets in a standard room. But the price on the box isn't the whole story:
- Installation still costs money unless you do it yourself.
- Filler panels and end panels add up.
- Awkward spaces are often wasted.
- Cheaper boards and hardware may need replacing sooner.
Custom joinery costs more initially, but you're paying for a perfect fit, better materials and professional installation. For a kitchen or built in that you plan to keep for 15 years or more, it's usually better value over its life. Our kitchen renovation cost guide shows how cabinetry fits into the overall budget.
Fit
This is where custom joinery really shines. Sydney homes are full of quirks: high ceilings in terraces, sloping ceilings in attics, walls that aren't square and alcoves beside chimneys. Flat pack can't adapt to these, so you end up with gaps, fillers and dust collecting tops.
Custom joinery runs wall to wall and floor to ceiling, uses every centimetre and looks like it was always part of the house.
Quality and durability
Quality varies in both categories, but custom joinery usually means:
- Better board materials, including moisture resistant boards in kitchens, bathrooms and laundries.
- Stronger construction and better edge finishing.
- Premium soft close hinges and drawer runners.
- A wider choice of finishes, including two pack painted surfaces and timber veneers.
Design flexibility
With custom joinery you can have exactly what you want: drawers sized for your saucepans, a hidden appliance cupboard, a wardrobe with more hanging space and fewer shelves, or a desk at precisely the right height. Flat pack gives you a set menu.
Time
Flat pack can be quick if it's in stock. Custom joinery takes a few weeks to manufacture after the design is approved, but installation is fast and professional.
When flat pack makes sense
- Simple, standard sized spaces
- Rentals and short term solutions
- Tight budgets where a basic fit out is enough
- Garages and utility areas
When custom joinery is worth it
- Kitchens you plan to keep for many years
- Built in and walk in wardrobes
- Entertainment units and media walls
- Awkward spaces, alcoves and high ceilings
- Butler's pantries, home offices and laundries
- Homes where a high end finish matters for resale

Frequently asked questions
Is custom joinery more expensive than flat pack?
Yes, custom joinery usually costs more up front. The difference shrinks once you factor in installation, filler panels, wasted space and the shorter lifespan of cheaper boards and hardware.
Can flat pack be customised?
To a point. You can choose door colours, handles and some configurations, but cabinet sizes are fixed. Awkward spaces end up with filler panels and gaps.
How long does custom joinery last?
Well made custom joinery with quality boards and hardware can last for decades. Hinges and drawer runners are the parts that wear, so it pays to use good ones.
