Why alcoves are the most underused space in a period home

Nearly every Victorian terrace, Edwardian villa and 1930s semi has them: the two narrow recesses flanking the chimney breast. They are usually somewhere between 30cm and 45cm deep, a metre or so wide, and almost always choked with a lamp, a stack of paperbacks and a tangle of extension leads. Handled properly, they become the hardest-working storage in the house — and you would never know it to look at them.

The appeal is that the space is already there. You are not extending, not stealing floor area from another room, and not introducing a piece of furniture that will never quite fit. Bespoke joinery in an alcove fills dead volume from skirting to ceiling, which is precisely the volume that off-the-shelf shelving wastes. The trick is to decide, before a single board is cut, what you want to hide and what you want to show.

Measure twice: the checks that save a joinery bill

Old walls are rarely straight, and alcoves are among the worst offenders. Before you commit to anything, take measurements and expect them to differ.

• Width at the top, middle and bottom of the recess — splayed walls are common, especially on lath and plaster.
• Height from floor to ceiling, and the depth from the back wall to the front face of the chimney breast.
• The height and projection of existing skirting, so the joinery can be notched around it rather than forced over it.
• Anything fixed to the wall: radiators, sockets, aerial points, gas or electric meters, alarm panels.

One useful decision comes early. If you build the joinery forward so its front face sits flush with the chimney breast, you gain 80–150mm of extra depth — the difference between a cupboard that takes a box file and one that does not. That means measuring from the back of the recess to the front of the breast, not the depth of the recess alone.

Low cupboards with doors: the dependable base

The bottom 500–600mm of an alcove is uncomfortable to reach into and ideal to close off. A run of low cupboards here gives you somewhere for the things nobody wants on display: board games, wellington boots, the printer, a box of cables, cleaning supplies, bulk kitchen rolls.

Doors matter more than the carcass. A simple shaker panel, tongue-and-groove or a flat front with a slim beading all sit happily in a period room; fussy mouldings on a small alcove just look busy. Soft-close hinges, small turned knobs or discreet push latches, and a coat of the same colour as the walls will make the whole thing recede. If the alcove houses a radiator, keep a slatted or louvred panel in front of it so heat can still move, and never box a radiator in solidly.

Shelving above: open, closed or a deliberate mix

The strongest arrangement is usually a split. Doors below waist height, open shelving at eye level for the things you actually enjoy looking at — books, ceramics, a framed photograph, a good lamp — and closed cupboards again in the top 50cm, where objects go to be forgotten.

Shelf spacing of 300–350mm suits most hardbacks. Fixed shelves are stronger and cheaper; adjustable ones on a drilled ladder of peg holes are more forgiving when your collection changes shape. If you want the shelves to disappear, paint the inside of the alcove the same colour as the walls, or go one shade darker for depth. A deep colour inside open shelving — forest green, slate blue, a soft aubergine — looks wonderful against pale walls and makes whatever you place there look considered rather than merely stored.

Hiding the everyday: cables, toys and paperwork

This is where alcove joinery earns its keep. Plan a dedicated media cupboard with a back panel you can drill through, so routers, games consoles and set-top boxes live out of sight. Two practical points: cut a 40mm grommet hole or slot for cables to pass through, and add ventilation. A router or console in a sealed cupboard will overheat, so fit a couple of 50mm vents low and high, or use a louvred door. Run a length of flexible conduit behind the joinery for cables, use a brush plate where they emerge, and secure them with hook-and-loop ties rather than zip ties you will have to cut off later.

For toys, deep low cupboards with two wide doors are the workhorse. Pair them with baskets — seagrass, jute, felt, woven willow — measured to the shelf so there is no wasted gap either side. A basket is also a psychological trick: children will tidy into a basket when they will not tidy onto a shelf, and visitors see texture rather than plastic.

Paperwork deserves its own drawer rather than a shelf, and a shallow one at around 750mm high means you can pull it out and leaf through it standing up. Box files fit neatly if the internal depth is at least 320mm. If you keep passports, deeds or anything sensitive, specify one lockable cupboard in the run and keep the key somewhere you will actually remember.

Materials and finishes that suit an old room

For painted joinery, MDF and tulipwood both work well; tulipwood takes paint beautifully and holds a screw better at the edges, which matters on narrow stiles. For a visible timber finish, oak or pine with a wax or hardwax oil looks warm without shouting. Finish painted work in a durable eggshell or a hard-wearing water-based paint, and allow it to cure for a week or two before you load the shelves.

Because old walls move and bow, scribe the joinery to the wall rather than trusting a straight edge, then fill the remaining gaps with decorator's caulk and paint over. Line the shelves with felt or a plain paper to stop items scratching, and leave a small void behind the plinth so the whole unit can breathe. It is a little more fuss than flat-pack, but an alcove fitted this carefully gives you a room that looks calmer, tidier and considerably larger — while quietly swallowing half the clutter you used to trip over.
