Both have their place. Flat pack joinery is affordable, widely available, and absolutely fine in the right context. But there are real, practical differences between it and custom timber work — and the people best placed to explain those differences are the ones who work in timber every day.
At Impact Build, our builders are qualified carpenters who manage a team of qualified carpenters. We work with both. Here's what we observe.
The most significant difference is fit. Flat pack is built to standard dimensions, which means most rooms — with their irregular widths, angles, and ceiling heights — get worked around rather than worked with. Fillers, reduced-depth cabinets in awkward corners, and small gaps are the practical result. Custom joinery is designed for the specific dimensions of the space.
The second is lifespan. Flat pack cabinet carcasses are generally particleboard or MDF with a laminate finish. When they fail — a swollen base, a stripped hinge hole, a delaminating door — they can't be repaired in any meaningful way. They're replaced. Custom timber or quality plywood construction is repairable. Hinges can be re-hung, surfaces can be refinished, doors can be remade. It doesn't degrade the way flat pack does; it ages.
The third is selection. With custom work, the species, profile, grain direction, and finish are chosen to suit the home. Not what's on the shelf.
