Built-in storage — floor-to-ceiling alcove units, hidden-door cabinetry, boot room and utility joinery — is sold on the promise that it will look like part of the house rather than a piece of furniture bolted on. Getting that requires specific fixing and scribing detail that a vague quote glosses over.
The other half of the job is load: shelving in a boot room or utility cupboard often carries more weight than a bedroom wardrobe, and the shelf support and back panel need to be specified to match.
Fixing to the wall structure
Floor-to-ceiling units need fixing points identified before build — into masonry, timber studwork, or a mix where a chimney breast meets a stud partition. The quote should confirm whether the fitter has checked wall construction at survey or is assuming it, since fixing a heavy loaded unit into plasterboard alone with no stud behind it is a genuine failure risk.
For push-to-open or hidden-door cabinetry, the mechanism brand and the clearance tolerance around the door edge should be stated, because these mechanisms need tighter, more consistent gaps than standard hinged doors to trigger reliably.
Shelf load rating and back panel
Adjustable shelving should state the board thickness and span, since a 18mm shelf spanning more than about 800mm under real load (books, tinned goods, tools) will sag visibly over time without a central support or a thicker board. The quote should confirm shelf spans against intended use.
Back panels for boot room or utility storage carrying boots, coats and cleaning equipment should be a proper 8-12mm panel, not a thin hardboard skin, since these units see heavier daily impact than a display cabinet.
Scribing to alcove and skirting detail
Alcove units need scribing to both side walls and the ceiling — alcoves in older houses are rarely a true rectangle, and a unit built to the drawn dimension only, without a site template, risks a visible gap on one side. The quote should confirm whether a template visit happens before manufacture.
Skirting detail at the base of the unit should be specified too — either the unit is scribed over existing skirting, or the skirting is removed and the unit sits down to the floor, each giving a different finished look and a different labour cost.
Finish and hardware
Push-to-open catches, soft-close hinges and any concealed lighting transformer location should be named, along with the finish (painted, spray-finished, veneered) and number of coats, matching the standard expected of any painted fitted joinery.
What gets missed on cheap quotes
Electrical work for any lighting inside the unit, and making good to walls, ceiling and skirting once the old space is cleared, are common gaps. So is confirmation of ventilation for any enclosed storage housing electrical items (a router, a boiler cupboard extension) which needs airflow specified, not sealed in.
Common questions
How do you know if a wall can take a heavy fitted unit?+
The fitter should check the wall construction at survey — masonry, studwork, or a mix — and identify fixing points before the unit is built, rather than assuming a wall will take the load once it's on site.
Why does shelf span matter?+
An 18mm shelf spanning too far under real load will sag visibly over months, particularly with books or tinned goods. The quote should confirm shelf spans and add central support or thicker board where the span is long.
Should the quote include a site template visit before building alcove units?+
Yes, ideally. Alcoves in older houses are rarely square or the same width top and bottom, and templating on site before manufacture reduces the risk of a visible gap on installation day.
