How Do You Build a Built-in Wardrobe from Scratch?

Building a built in wardrobe from scratch follows a fixed order: survey the space, design the internal layout, build a level base and a stud frame, clad it, fit the interior, then hang the doors and finish. Get the base level and the frame plumb and everything afterwards falls into place. Rush those two stages and every door gap will show it.

The whole job is well within reach of a competent DIYer with basic power tools. What it demands is patience with measuring, because almost no UK room is truly square, and a willingness to work to the actual walls rather than to the dimensions you wish they had.

Survey the space honestly

Measure the width at floor level, at mid height and near the ceiling. Do the same for the height at both ends and in the middle. Write every figure down. Differences of two or three centimetres across a run are entirely normal in older properties.

Check for square by measuring the diagonals of the floor area, and check the walls for plumb with a long level. Note the position of every socket, switch, radiator pipe and vent, and the swing of the bedroom door.

Look up as well. Find the direction of the ceiling joists so you know where you can fix the head plate, and check whether the ceiling has a downstand or a sloping section. In loft rooms and older extensions, the ceiling is often the constraint that shapes the whole design.

Design the interior before the exterior

Decide what goes inside first, then build a box around it. Working the other way round is how people end up with a beautiful wardrobe that does not hold their clothes.

Allow around 150cm of drop for long coats and dresses, and 100cm for shirts, blouses and jackets. Shelves need 30cm to 35cm of depth for folded items. Hanging sections need around 55cm of internal depth so hangers sit square.

A common and effective layout in a 240cm ceiling height is a long hanging section on one side, a double hanging section beside it, a drawer bank at the base of one bay, and a full width top box above everything for luggage and off season storage. Sketch it as an elevation with real numbers before you buy any timber.

Build a level base

Fix a sole plate of 47mm by 75mm timber to the floor along the front line of the wardrobe and along each return. Check for level constantly and pack underneath with slate or plastic shims where the floor dips.

This is the most important half hour of the project. Every vertical, every shelf and every door reveal references back to this base. A base out by 8mm across two metres will produce door gaps that taper visibly.

If the floor is carpeted, decide now whether the wardrobe sits on the carpet or on the boards. Fixing to the boards is neater and makes future flooring changes much easier, though it means cutting the carpet back.

Frame it

Erect vertical studs at each end and at every bay division, fixing them plumb to the walls where there is masonry or timber behind. Add a head plate at the top, fixed into the ceiling joists.

Put noggins in wherever you will later fix something: rail brackets, shelf supports, the tops of drawer banks and the top box floor. It is far easier to add noggins now than to hunt for something solid to screw into later.

Keep checking plumb as you go, and check that the front faces of all your studs sit on the same plane. Run a string line or a long straight edge across the front of the frame. A frame that bows forward in the middle will never take flat doors neatly.

Clad and scribe

Use 18mm MDF or plywood for the visible carcass, and 6mm to 9mm for the back if you want one, although a built in unit can often use the plastered wall as its back.

Cut every panel slightly generous and scribe it to the wall. Scribing means transferring the actual undulating line of the plaster onto the panel with a compass or a block and pencil, then cutting to that line. It takes a few extra minutes and it is the difference between joinery that looks fitted and joinery that looks stuck in place with a bead of filler down the side.

Continue the room’s skirting profile across the base of the unit, or cut the carcass to sit down over the existing skirting. Either reads as built in. A carcass that simply stops on top of the skirting does not.

Fit the interior

Install shelf supports, rails and any drawer runners while the front is still open and you have full access. Use a story stick to mark shelf heights so both sides match exactly.

Adjustable shelf supports are worth choosing over fixed shelves. Storage needs change, and drilling a line of holes now costs nothing compared with rebuilding later.

Set rails at the heights from your design sketch, with brackets fixed into the noggins you installed. Check the rail is level with a spirit level rather than measuring down from the ceiling, since the ceiling is unlikely to be level itself.

Hang the doors

Doors go on last. Concealed hinges with three way adjustment are the sensible choice, because they let you tune height, depth and side to side alignment after the fact.

Aim for a consistent 3mm gap around and between doors, and use cut spacers rather than judging by eye. Hang all the doors before you adjust any of them, then work along the run balancing the gaps as a set.

If the opening is very wide or the walkway is tight, sliding doors are worth considering instead. They need no swing clearance, though they demand a level track and add depth. Comparing what is available across our modern sliding wardrobes UK sale range gives a useful sense of how the systems work before you commit to building around one.

Finish properly

Fill and sand all fixings, then seal MDF edges with a thinned coat before topcoat, otherwise the edges will drink paint and look furry. Two thin coats of a good eggshell or satin beat one heavy coat every time.

Inside, a clear water based finish keeps the interior bright and wipeable without leaving a lingering smell on clothes. Add battery powered lighting strips if the interior is dark, which most built in wardrobes are.

Deciding whether to build at all

Be realistic about cost and time. Sheet materials, hinges, runners, rails, doors, fixings, paint and the odd tool add up, and a full wall build is a weekend or two of solid work.

Where the wall is straight and standard, a freestanding unit may give you the same capacity for less outlay and none of the labour, and it moves house with you. Building from scratch earns its place when the space is genuinely awkward: sloping ceilings, chimney alcoves, stair bulkheads or unusual widths.

A hybrid often makes the most sense. Build only the section that no manufactured unit can fit, and use ready made pieces elsewhere. Our modern wardrobes UK sale range covers the standard sizes, a modern chest of drawers UK sale handles folded storage without any joinery, and the wider modern bedroom furniture UK sale collection helps you match finishes between built and bought. At Furniture in Fashion we see this combination work well in exactly the rooms where a full bespoke fit out would be hard to justify.

Safety and services

Never box in a radiator, a gas appliance flue or an electrical consumer unit. Do not cover a socket that you may need, and do not run new electrical work yourself unless you are competent and comply with the relevant regulations.

Check for pipes and cables before drilling into walls, particularly in the zones above and below sockets and switches. Fix the frame to the structure at high level so the unit cannot move, and put the heaviest storage at the bottom.

Frequently Asked Questions

What is the correct order for building a built in wardrobe?

Survey the space, design the interior, build a level base, erect and plumb the frame, clad and scribe the panels, fit the interior, then hang doors and finish.

How deep should a built in wardrobe be?

Around 55cm to 60cm internally for front to back hanging. Shelf only sections can be 30cm to 35cm, and fitted work lets you vary depth along a run.

Do I need a back panel on a built in wardrobe?

Not always. A plastered wall in good condition can serve as the back. On a cold external wall, a back panel with a small air gap is the safer choice.

Why does scribing matter?

Walls in most UK homes are neither flat nor plumb. Scribing panels to the actual wall line removes the gaps that make joinery look added on rather than built in.

Is building a wardrobe cheaper than buying one?

Not necessarily once materials, hinges, doors and paint are counted. Building pays off in awkward spaces such as sloping ceilings and alcoves where no manufactured unit fits.
