The wardrobe decision is usually framed as a taste question. It is not. It is a volume question, and the arithmetic almost always points the same way once you measure the storage you actually get rather than the furniture you actually buy.

Freestanding wardrobes win on purchase price and on the flexibility to take them when you move. Fitted wardrobes win on usable cubic metres — particularly in London bedrooms, which are typically 3–5 m wide with irregular walls, a chimney breast and a ceiling that is not level.

This guide sets out the dimensions that decide it: the depth you lose inside a carcass, the depth you lose again to an out-of-square wall, the ceiling void a freestanding unit never uses, and the details that make fitted joinery look architectural rather than boxy.

The numbers side by side

Prices are indicative for Greater London including installation and VAT. The comparison that matters is not the headline cost but the usable storage per pound, which is where the fitted run overtakes a freestanding set in most London bedrooms.

1. The depth you lose inside the carcass

A wardrobe needs 600 mm of internal depth for a full-height hanging rail to hold standard hangers facing the right way. Anything less and the hangers sit at an angle, the shoulders of coats press against the back panel, and on a sliding or hinged door the clothing can catch as the door moves.

That 600 mm is internal. A fitted carcass takes roughly 80 mm for the back panel, the carcass side and the door — 18 mm board, a 30–40 mm door, and the running clearance. Then add the scribe panel: where a wall is out of square, which in a Victorian or Edwardian London terrace is the norm rather than the exception, a scribed filler of up to 50 mm is needed to close the gap between the unit and the wall.

So the external depth of a properly detailed fitted run is 650–700 mm. A freestanding wardrobe is usually 580–650 mm external, which leaves 530–560 mm internally — enough for most clothing, tight for a long coat on a wide hanger. The typical London bedroom, at 3.0–3.6 m wide, can spare the extra 50–70 mm on one wall, and usually cannot spare it on two.

2. The space a free-standing unit never uses

Freestanding wardrobes need a gap behind them for skirting and uneven walls, and they stop 300–600 mm below the ceiling. That void is the most valuable storage in the room and it is the reason fitted joinery usually wins on volume.

In a room with a 2.4 m ceiling and a 1.9 m freestanding wardrobe, half a metre of height across the full run is doing nothing at all. A fitted unit takes that space for a top box — suitcases, seasonal bedding, the things that currently live in the loft or on top of the wardrobe looking untidy. In a London flat where there is no loft, that space is not a nicety; it is the difference between a calm bedroom and a cluttered one.

Fitted also solves the alcoves. Chimney breasts, boxed-in pipes and stepped walls waste floor area when you are trying to arrange rectangles of furniture. A fitted run absorbs those irregularities into the joinery, so the room reads as one flat elevation rather than a collection of gaps.

3. The shadow-gap reveal at the ceiling line

The detail that separates architectural fitted joinery from a boxed-in carcass is the 5 mm shadow-gap reveal. Instead of scribing a filler to a wavy ceiling, the top of the unit stops 5 mm short, producing a crisp dark line that runs the length of the run. It reads as deliberate, it tolerates a ceiling that is not level, and it beats any cornice or decorative trim.

Two conditions make it work. First, the ceiling must be reasonably level across the run — if it drops 30 mm over 3 m, a 5 mm gap becomes uneven and the reveal stops reading as intentional. Second, the gap must be consistent: mark it from the ceiling, not from the top of the carcass, and check it at both ends and the middle before the unit is fixed.

Where the ceiling is genuinely bad, the honest options are to overboard and skim it first, or to accept a scribed filler and lose the reveal. Doing the reveal badly is worse than not doing it at all.

4. Internal LED strips done properly

Internal lighting transforms a wardrobe from a dark box into something you enjoy using. Two positions do the work: a strip at the underside of the top rail, so the hanging area is lit, and a strip under each shelf, so folded items are visible without digging.

Keep the colour temperature at 2700 K to match the bedroom lighting, use an aluminium channel with a diffuser so no diodes are visible, and specify a door-activated switch so the light comes on only when the door opens. A strip that stays on when the door is closed is a nuisance and a heat source inside a closed cabinet.

Two practical points. Run the cable in the carcass during assembly, not afterwards, and leave the driver accessible — usually in the top box or behind a removable back panel. A driver sealed inside a fitted carcass is a future problem in a room that is expensive to disturb.

5. Soft-close runners and concealed hinges

Hardware is where cheap fitted wardrobes reveal themselves within two years. Drawers are opened more often than doors and carry more weight, so runners fail first.

Specify steel ball-bearing soft-close runners with a 5–10 year warranty for an owner-occupied home, stepping up to full-extension undermount runners for deep drawers used daily. Basic zinc-alloy soft-close runners — the ones that come with a flat-pack carcass — commonly sag or stop closing flush at around eighteen months. Undermount runners also keep the mechanism out of sight, which matters when a drawer is open.

Hinges should be concealed-fix from mid specification upwards, with no visible screws on the door face. Exposed-screw hinges belong on basic specification only. And the same rule that applies everywhere else in the house applies here: never mix hardware tiers within one run of furniture, because the difference in how a door closes is noticed immediately.

What it costs — and when freestanding is right

A 3 m fitted run in a London bedroom typically lands £2,800–£7,500 installed including VAT, depending on door finish, internal fit-out, lighting and hardware tier. Sprayed finish, internal drawer banks and integrated lighting sit at the top of that range; a simple melamine carcass with slab doors sits at the bottom.

Freestanding is the right answer when the tenancy is short, when the budget is genuinely committed elsewhere in the renovation, or when the room is a spare bedroom used occasionally. It is also the right answer when the walls are so far out that a fitted run would need an unusually deep scribe — although in that case, a fitted run with a deeper service void may still be cheaper than making the wall straight.

We build fitted storage through our fitted wardrobes and joinery service as part of a wider refurbishment or as a standalone install, working across Haringey and the rest of Greater London. For how a bedroom fit-out sits within a whole-house budget, see our renovation cost per square metre guide.

Frequently asked questions

How deep should a fitted wardrobe be?

Allow 600 mm internal for a full-height hanging rail, about 80 mm for the carcass and door, and up to 50 mm for a scribe panel against an out-of-square wall — so 650–700 mm external. Below 550 mm internal, hangers sit at an angle.

Are fitted wardrobes cheaper than freestanding?

Rarely cheaper for the same volume, but usually better value per usable cubic metre. Freestanding units waste the space behind and above and never reach the ceiling; a fitted run uses the full volume including the top box.

What is a shadow-gap reveal?

A 5 mm gap between the top of the joinery and the ceiling, producing a crisp dark line instead of a scribed filler. It is the detail that makes fitted furniture look architectural, and it needs a reasonably level ceiling to stay consistent.

Which drawer runners should I specify?

Steel ball-bearing soft-close runners, 5–10 year warranty, stepping up to full-extension undermount runners for deep drawers used daily. Basic zinc-alloy runners commonly fail at around eighteen months.

Do fitted wardrobes add value to a London home?

Well-executed fitted storage is one of the strongest room-level improvements for resale, because it solves a problem buyers recognise immediately. In small London bedrooms the gain in usable storage per square metre is the selling point.
