Joinery and Wardrobes: Where the Money Goes in Fitted Furniture

Two wardrobes that look identical can differ substantially in price. The difference sits in the carcass board, the edges, the hardware and who measured the opening.

Fitted joinery is one of the few parts of a build where the owner can see almost nothing that matters. The carcass board, the edge treatment, the back panel, the hinge and runner quality and the accuracy of the site measurement are all hidden behind a door front that was chosen from a sample. This breakdown shows which lines carry the cost and which ones determine whether the piece still works in ten years.

What this number does and does not include

This covers fitted internal joinery: wardrobes, kitchen units, vanities, shelving and feature panelling, from survey through fabrication to installation. It excludes loose furniture, appliances, stone worktops which are usually a separate package, and the electrical or plumbing work that serves a kitchen. It assumes a bespoke or semi bespoke supplier making to site dimensions rather than a flat pack purchase.

Carcass board and its moisture resistance

The box behind the door is the structural part and usually the largest material item. Standard board, moisture resistant board and plywood differ in price, in weight, in how well they hold a fixing and critically in how they behave if they get damp, which matters in a kitchen or a vanity rather than a bedroom wardrobe.

• Pushes it up: Moisture resistant grades, plywood construction, thicker boards and larger units.
• Brings it down: Using the appropriate grade room by room rather than the highest grade throughout.
• How to control it: Specify the board type per location and ask the supplier to state it on the quotation rather than describing it as high quality.

Door fronts and finish

The visible surface, and the item buyers compare. Options range from laminate and foil wrapped board through sprayed lacquer to real wood veneer, and the cost gap between them is wide. Finish also decides repairability: a lacquered door can often be touched up, while a damaged foil wrap generally cannot.

• Pushes it up: Sprayed finishes, veneers with matched grain, high gloss surfaces and large single panels.
• Brings it down: Reserving premium finishes for the doors people see and touch, with simpler finishes inside.
• How to control it: Approve a physical sample of the actual finish under the lighting of the finished room before fabrication.

Edge treatment and sealing

Every cut edge is where moisture enters a board and where damage starts. Edge banding thickness, the adhesive used and whether every edge, including the hidden ones, is sealed are quiet cost items with long consequences. A swollen bottom rail under a basin is almost always an unsealed edge.

• Pushes it up: Thicker edge banding, matched edges on visible surfaces and full sealing of all internal edges.
• Brings it down: Standardising on one edge treatment rather than specifying several across the project.
• How to control it: Inspect a completed unit before delivery and check the edges that will never be visible again.

Hinges, runners and lift mechanisms

Hardware is the part that moves thousands of times and therefore the part that fails. Soft close hinges, full extension runners with load ratings and lift systems for tall doors cost considerably more than basic equivalents, and they are the difference between joinery that still closes properly in a decade and joinery that does not.

• Pushes it up: Soft close everywhere, heavy duty load ratings, tall or wide doors needing special mechanisms.
• Brings it down: Applying premium hardware to doors and drawers in daily use and standard hardware to rarely opened units.
• How to control it: Require the hardware brand and model on the quotation, and keep the data so replacements can be matched later.

Internal fit out and accessories

Drawers, pull out baskets, trouser rails, lighting, dividers and adjustable shelving are each priced individually and together they can rival the carcass cost. They are also where joinery becomes genuinely useful, so they are not a place to cut blindly.

• Pushes it up: A high count of drawers, pull out mechanisms, integrated lighting and bespoke internal configurations.
• Brings it down: Choosing accessories by how often they will actually be used rather than by catalogue appeal.
• How to control it: Walk through the internal layout of each unit against how the room will be used before approving the drawings.

Site survey and the accuracy of the opening

Bespoke joinery is made to measured dimensions, and if the walls are out of plumb, the floor is not level or the ceiling drops across the opening, either the joinery is made to fit the error or it arrives and does not fit. Surveying after plaster and before fabrication is the cheapest insurance in the package.

• Pushes it up: Rooms that are out of tolerance, requiring scribes, filler panels and adjustment.
• Brings it down: Getting the plaster and screed within tolerance so the joinery can be made to nominal dimensions.
• How to control it: Make a post plaster dimensional survey a named deliverable before any unit goes into production.

Delivery, protection and installation

Finished joinery has to reach a finished room without being damaged, through a building where other trades are still working. Installation labour, protection materials, and the storage required when a room is not ready all cost money, and damage in transit or on site causes delay as much as expense.

• Pushes it up: Upper floors without a lift, long storage periods on site and installation among other active trades.
• Brings it down: Sequencing so joinery arrives into completed, lockable rooms and is installed once.
• How to control it: Agree a delivery sequence tied to room completion rather than to the fabrication schedule.

Worktops and the interface with other trades

Where joinery meets stone worktops, sinks, hobs and appliances, somebody has to own the tolerance and the cut outs. That interface is a frequent source of extra cost, because a template taken after the carcasses are installed is accurate and a template taken from a drawing is a gamble.

• Pushes it up: Multiple cut outs, special edge profiles and appliances with tight tolerances.
• Brings it down: Fixing the appliance selection early so the cut outs are known before templating.
• How to control it: Template worktops from installed carcasses and confirm appliance dimensions in writing before cutting.

Costs that never appear on the first page

• Remeasuring and refabricating units made from drawings rather than from a site survey.
• Filler panels and scribes to absorb walls and ceilings that are out of tolerance.
• Repairs to finished joinery damaged by trades still working in the room.
• Power and data outlets relocated because the joinery layout changed after first fix.
• Lighting transformers and drivers that need accessible positions nobody allocated.
• Adjustment visits after the first few months, as doors settle and need realignment.

Keeping the budget honest

Spend on what moves and what gets wet, and economise on what is hidden and dry. Hardware and moisture resistant board in kitchens and bathrooms repay their cost; a premium board in the back panel of a bedroom wardrobe does not. The other rule is sequencing: joinery priced before the rooms are measured is an estimate, and the gap between that estimate and the final invoice is almost always filled by adjustments for site dimensions, so get the survey done before you accept the number.

• At design stage, when the internal layout of each unit is agreed against how the room will be used.
• At quotation, confirming board grade, finish, edge treatment and hardware brand are all stated.
• After plastering, when the dimensional survey is taken and before fabrication starts.
• At the first completed unit, inspected in the workshop or on first delivery.
• At handover, with an adjustment visit scheduled a few months later as part of the agreement.
