A real-world plan for diy built in wardrobes (with the bits people skip)

Summary: DIY built in wardrobes are half measuring problem, half assembly problem. The best shortcut is to measure the alcove properly, plan for uneven walls and floors, and order the doors or panels pre-cut where precision matters.

The first DIY wardrobe project I tried was a 2.14 m gap between a chimney breast and the bedroom door. I had a circular saw I'd borrowed, a sheet of 18 mm MDF that turned out to be 18.2 mm, and a confidence level that lasted exactly until the first cut. The MDF tore on the underside. The hinge holes ended up 4 mm off. I tried again. By the third weekend I had something that closed if you slammed it the right way.

That was the moment I started thinking about how diy built in wardrobes are actually two jobs glued together. The carpentry is one. The figuring-out-what-fits is the other. Most blog posts cover the first and skip the second, which is why so many DIY wardrobes end up looking like a kitchen unit pretending to be furniture.

This is the version I wish I'd had on weekend one.

Measure the gap, not the wall

Walls aren't square. You knew that. But it's still the bit people forget when they're sketching on a Sunday morning with coffee that's already gone cold.

Measure the alcove or recess at three heights: 10 cm above the skirting, halfway up, and 10 cm below the ceiling line. In a typical Edwardian or Dutch interwar house you'll see 1 to 2.5 cm of variation. My Amsterdam flat had 1.8 cm of taper over 2.4 m of height, which sounds small until you try to slide a 2.38 m side panel into a 2.365 m gap.

Measure depth at two points too. Skirting boards push the bottom forward. If you're planning a wardrobe with a hanging rail (so, almost any wardrobe), the inside depth needs to clear 58 cm. That means 60 cm external minimum, plus whatever the back panel adds. The standard advice is "55 to 60 cm depth". The standard advice gets you a wardrobe that snags shirts on the door.

Floor flatness matters more than you'd guess. A 6 mm dip across a 2 m run is normal in older buildings. You can shim it later, but only if you've planned for an adjustable plinth at the bottom, not a fixed one.

Carcass first, doors last (and don't kid yourself about the doors)

Here's the order I'd use now if I were starting over, with a real budget for a 2.14 m wide by about 2.4 m tall fitted wardrobe:

• 18 mm birch ply for the carcass. Three sheets for a single-bay wardrobe, four if you're adding a divider. About 380 to 480 euros at the Dutch yards I've used. MDF is cheaper, around 180 euros, but the edges are powdery and the screws don't bite as well.
• A 50 mm by 25 mm batten frame at floor and ceiling. Pine is fine. Get it straight, not pretty.
• One hanging rail (oval section, not round, because round rails spin shirts off the hangers). A 32 mm oval rail in steel runs about 35 euros for the length plus brackets.
• Cam locks and dowels for the carcass joints if you don't want to faff with pocket holes. About 40 euros for a wardrobe's worth.

Doors are where DIY built-in wardrobes usually fall apart. Literally and figuratively. A 60 cm wide hinged door needs three concealed hinges, properly aligned, with the carcass face perfectly flush to the wall. Sliding doors need a track that's level to within 2 mm over the full run, which sounds easy and isn't.

If you're doing diy fitted wardrobes for the first time, my honest take is to build the carcass yourself and order the doors pre-made. The hinge holes will be drilled to spec, the edges will be banded, and you won't be sanding a botched 3.8 cm chamfer at midnight. A pair of pre-finished doors for a 2.14 m bay sits around 280 to 420 euros depending on finish. Worth it.

The weekend it actually takes

People online claim a weekend. People online lie. A realistic timeline for a single-bay built-in, if you've never done one before:

• Day 1 (4 to 5 hours): measuring, cut list, order materials, sketch the layout. If you're using diy fitted wardrobe kits, this is also when you check the kit dimensions against your alcove and curse quietly.
• Day 2 (6 to 8 hours): batten frame to wall, base levelled, side panels in, top panel in, back panel scribed to the wall. The scribing takes longer than you think.
• Day 3 (4 to 6 hours): internal divider, shelves, hanging rail.
• Day 4 (3 to 5 hours): doors hung, handles, plinth. Adjusting hinges. Re-adjusting hinges. Adjusting them again because the door rubs on the carcass at the top right.

That's 17 to 24 hours of actual work for someone who knows what a Forstner bit is. Add 30 percent if it's your first time.

Where the money usually goes wrong

A rough budget for a 2.1 m fitted wardrobe, all in:

• Materials (carcass, frame, rail, hardware): 480 to 620 euros
• Doors (pre-made, two hinged): 280 to 420 euros
• Tools you didn't realise you needed (Forstner bit, jigsaw blades for laminate, a 1.2 m spirit level that's actually flat): 80 to 150 euros
• Paint or oil if you're not using pre-finished ply: 60 to 90 euros
• A repair kit for the bit you'll mess up: another 40 euros, trust me

Total: somewhere between 940 and 1,320 euros, plus a long weekend or two. A local carpenter would quote 2,800 to 4,500 for the same wardrobe. The savings are real, but they're not the "fitted wardrobe for 200 euros" you see on Pinterest.

What I'd skip and what I'd keep

Skip: any tutorial that starts with "all you need is a drill". You also need a track saw or a circular saw with a guide, a clamping setup, and somewhere to cut sheets that isn't your kitchen floor.

Keep: the bit where you scribe the back panel to the wall. It's fiddly, but it's what makes the difference between something fitted and something parked-against-the-wall.

If you're sizing up a tricky alcove and want to skip the cut list, the Forstner bit, and the lost weekend, that's the kind of thing knuslabs.com was built to solve.
