Start by understanding the alcove
Alcoves in period and altered properties vary widely. Two recesses in the same room may not match, walls may lean, floors may slope and skirting boards may reduce the usable width at floor level. There is no dependable “standard chimney-breast size”, so a generic dimension should never replace a site measurement.
Decide whether the aim is to place a freestanding wardrobe inside the recess, create a fitted appearance with fillers, or commission a genuinely made-to-measure installation. These are different projects with different tolerances, costs and reversibility.
Measure width, height and depth at several points
Use millimetres and record the opening rather than a single central measurement. Measure width near the floor, around the middle and close to the ceiling. Repeat the process for height on the left, centre and right, then measure depth on both sides.
- Mark skirting, coving, picture rails and window boards.
- Record sockets, switches, pipes, radiator valves and vents.
- Check the front opening as well as the rear wall; an alcove can narrow towards the front.
- Use the smallest relevant dimension when checking a freestanding product.
- Confirm the supplier's required assembly and fitting tolerance.
Photographs and a simple annotated sketch reduce mistakes when comparing models or briefing an installer. Our guide to common wardrobe buying mistakes covers delivery and measurement errors worth checking before purchase.
Check the chimney breast, wall and concealed services
Placing furniture in an alcove is not the same as removing or altering a chimney breast. Do not cut, chase or drill deeply into chimney masonry without understanding the construction, whether a flue remains in use and what services may be concealed nearby.
Cracking, loose masonry, stained plaster, a removed fireplace or evidence that part of the chimney breast has previously been taken out should be assessed before installation. Structural alteration, work to a party structure or changes to a listed building can require specialist advice and formal permissions; ordinary furniture installation does not automatically trigger those requirements.
| Area | Proceed when | Pause and investigate when |
|---|---|---|
| Dimensions | The smallest width, height and depth suit the exact unit and fitting tolerance. | The opening narrows, the floor slopes significantly or packages cannot reach the room. |
| Wall and chimney | Surfaces appear sound and the chimney or flue arrangement is understood. | There is cracking, staining, loose masonry or evidence of earlier alteration. |
| Services and airflow | Sockets, valves, vents and access panels remain safely accessible. | The plan would conceal a service, block a vent or require drilling near an unknown service. |
| Installation | The floor and suitable restraint points have been identified. | A safe fixing method cannot be established for the actual construction. |
Choose the right wardrobe format
- Freestanding hinged wardrobe: simple to replace and move, provided the doors have room to open.
- Freestanding sliding wardrobe: useful where the bed or circulation route leaves little door-swing space.
- Fitted-look arrangement: a standard unit combined with carefully planned side or top fillers; confirm that ventilation and service access remain available.
- Made-to-measure fitted wardrobe: can use an irregular recess closely, but is less portable and normally needs a detailed site survey.
For compact rooms, compare these choices with our guide to sliding wardrobes in small bedrooms.
Allow for usable depth and door access
External depth does not equal usable hanging depth. Back panels, doors, tracks and internal fittings all consume space, so check the internal specification rather than relying on the overall number. Full-size clothes hangers need enough depth to sit without garments rubbing against the doors.
Also test how the wardrobe will be used. Hinged doors need an unobstructed arc; sliding doors expose one section at a time. Drawers must open past door panels, bed frames and radiator valves. If the alcove is shallow, shelving or a combination of folded storage and front-facing rails may be more practical than conventional side-on hanging.
Resolve damp and ventilation before installation
Disused flues, external walls and historic defects can all contribute to staining or musty conditions around an alcove. A wardrobe can conceal those signs and slow evaporation if it is fitted tightly against the surface.
Do not rely on the wardrobe to hide a moisture problem. Identify and repair the cause, keep existing vents open and follow the manufacturer's rear-clearance guidance. Where plumbing, electrical equipment or access panels sit in the recess, preserve safe maintenance access.
Install and secure the wardrobe correctly
Check that the floor can support the unit evenly and that doors run or hang square after assembly. Use only the specified components and follow the sequence in the instructions. Tall furniture should be restrained as directed by the manufacturer using fixings appropriate to the actual wall.
A competent installer is the sensible choice where the alcove is badly out of square, the unit is unusually large, electrical lighting is included, the wall is uncertain or safe fixing points cannot be identified. Never block a room vent, heat source or required escape route.
Frequently asked questions
Can a standard freestanding wardrobe fit inside an alcove?
Yes, if its exact assembled dimensions fit the smallest part of the recess with the supplier’s required tolerance, and its doors, drawers and wall restraint remain usable.
Will both alcoves beside a chimney breast be the same size?
Not necessarily. Walls may lean, floors may slope and alterations may differ, so measure each recess independently at several points.
Can I drill into a chimney breast to secure a wardrobe?
Do not drill until the construction, flue status, concealed services and correct fixing method are understood. If any of those points are uncertain, use a competent installer or appropriate specialist.
What should I do if the alcove is damp?
Identify and repair the moisture source before installing furniture. Keep existing vents open, preserve service access and follow the wardrobe manufacturer’s clearance instructions.
