Planning Alcove Storage for Small Victorian Terraced Houses

Why Alcoves Earn Their Keep in a Narrow Terrace

Victorian terraces are tall where they cannot be wide. With rooms often only three to four metres across, the recesses either side of the chimney breast are the most valuable real estate in the house — and the most forgiving. They sit out of the traffic path, they rise the full height of the room, and they will happily swallow books, crockery, board games and the good whisky. Done well, alcove joinery looks as though it has always been there. Done badly, it is a permanent reminder that nobody measured the skirting.

Measure the Chimney Breast Before Anything Else

The chimney breast is the fixed point the whole design hangs on, and it is almost never square. Measure its width at the skirting, at waist height and just below the picture rail — a 20–30mm difference is entirely normal, particularly where the breast has been re-plastered. Then measure its projection into the room at the same three heights. Most Victorian breasts project 300–400mm, but they can taper, and modern flue boxing often sits proud of the original face.

Only then measure the alcoves themselves. Take the width at the front opening and again at the back wall, at both the top and bottom of the recess. Chimney breasts lean, and so do the walls running alongside them. Note the narrowest figure for each alcove — that is the number the joiner must work to.

Allow for Skirting, Radiators and Everything Already in the Way

Nearly every disappointing alcove job traces back to something that was assumed rather than checked. Walk the alcove with a notebook and record the following.

• Skirting: Victorian skirting commonly runs 150–300mm deep. A scribed filler or a plinth notched around it looks far better than a unit that stops short and leaves a gap.
• Radiators: If one sits in the alcove, decide early whether to keep it, move it to the chimney breast, or swap it for a vertical column. Joinery built over a radiator needs an open grille top and bottom, or it will simply cook the shelves.
• Services: Sockets, aerial points, stopcocks, gas meter boxes and alarm cables. Anything that needs future access should have a removable panel rather than a sealed back.
• Cornice and picture rails: Does the unit stop beneath them or run to the ceiling? Running to the ceiling looks more built-in but requires scribing at the top.
• Floor level: Victorian floors can drop 15mm across a metre. Adjustable feet and a separate plinth solve this neatly.

Add roughly 10mm of tolerance to every width. Never specify a unit to fit exactly, because it will not.

Assume Nothing Is Plumb, Square or Flat

Old lime plaster moves with the seasons and rarely survives a century without a few humps and hollows. Run a straight edge or spirit level across each alcove wall and note the deepest and shallowest points. A 15mm variance over a metre is common; 30mm is not unusual behind a radiator.

This is where scribe fillers earn their keep. A 30–50mm filler strip fixed to the side of a carcass can be planed on site to follow the wall exactly, then caulked and painted in. The result reads as one continuous run of joinery rather than a box pushed into a hole. If the back wall is especially wavy, consider a shallow false back set forward of the worst of it — you lose 20mm of depth but gain a surface that shelves and drawers can actually bolt to.

Depth, Doors and Proportions That Suit the Room

Alcove depth determines what the unit can honestly hold. As a rule of thumb, 300–350mm suits paperbacks, folded linen and display shelving; 450–500mm is needed for coats, boxes and anything with a lid. Going deeper than 500mm in a narrow room simply eats floor space you will miss elsewhere.

Open shelving keeps small rooms airy, but only where the contents are tidy. A good compromise is drawers or cupboards below waist height and open shelves above, with the shelf spacing varied to suit what you own rather than set at a uniform 300mm. Doors finished in the wall colour, or with a simple beaded frame, disappear into the room. Full-height doors with visible hinges and handles will not.

Get It All Onto the Drawings Before the Saw Comes Out

A decent set of drawings should show the chimney breast dimensions, both alcove widths at top and bottom, projection, skirting height and depth, radiator position, socket locations, floor fall and ceiling height at both ends. Mark where fillers will go and how wide they can be. Note the paint colour and finish, and whether the carcasses are to be painted or left in oak or birch ply.

Take photographs alongside the measurements, and take them again once the old units come out — the wall behind them is often the most revealing part of the job. Do all of this first, and the fitting becomes a satisfying couple of days rather than a fortnight of planing, packing and quiet swearing. Victorian alcoves reward patience, and they forgive almost everything except guesswork.
