ᐅ What should be considered when installing Billy bookcases in small recesses?

Hello everyone, I am planning to place several Billy bookcases from Ikea in small niches of my apartment. I am wondering what to specifically consider when positioning these shelves precisely in such small niches. I am especially interested in making the most efficient use of the limited space, possible stability or fixing issues, and also aesthetic aspects to avoid the shelves looking too cramped or bulky. Are there any special tips regarding which Billy models or accessories are particularly suitable for niches, or maybe modifications that could be helpful? Thanks for your experiences and advice!

Pay special attention to the exact dimensions of the niche. Billy shelves come in various heights and widths, so precise measurements are essential. Always secure the shelves to the wall, especially in niches, to ensure stability.

I am particularly concerned with making the best use of limited space, potential stability or mounting issues, and also the visual aspects, so that the shelves don’t look cramped or bulky.

Achieving a perfect fit in a niche is the most important step. Since Billy shelves have standardized dimensions (usually 80 cm (31½ inches) wide, 202 cm (79½ inches) tall, 28 cm (11 inches) deep), you should definitely measure the niche precisely before buying—not just the width, but also the depth and height! Sometimes niches are angled or not perfectly rectangular, so it might make sense to use small spacers or wooden strips to even out any irregularities.

Regarding stability: In small niches, there is little room for movement, which is generally good, but slight wall unevenness can create stress. That’s why I recommend securing all shelves to the wall with the included brackets. It’s important to mount the brackets properly using anchors suitable for the wall type (brick, concrete, drywall—use the appropriate anchors for your wall material).

As for appearance: If your niches are only a few centimeters wider than the shelf, it will look tight, but you can soften this with colors and lighting. White or light colors make spaces feel airier. Additionally, you can swap the shelf boards for versions with thinner panels to gain some space, but this requires some DIY skills.

I also suggest experimenting with different shelf boards—some narrower or deeper options are available that might fit your niche better. Often, it’s worth considering combining smaller shelving units to make the most of the space and create multiple functional sections.

One more tip: Check how the niche’s door or window opens to ensure the shelf won’t get in the way later. This issue is common especially with original niches in older buildings.

May I ask, what are the exact measurements of your niches?

Therefore, I recommend securing all shelves firmly with the included wall brackets.

I wouldn’t consider that an absolute rule, at least not for all alcoves. Depending on how tightly the shelf fits between the walls, it can have enough stability without needing to be screwed in. However, it’s essential to check beforehand whether the shelf leans or tips when loaded.

Also, you should consider whether securing for high stability might be problematic in small rental apartments due to drilling holes. In such cases, alternative options that don’t require wall fixing might be better.

I think that’s important if you don’t want to force a standard solution. Often, arranging several smaller units side by side is more practical than a single large shelf. However, the question then arises whether that still achieves the desired look, or if it appears more like an improvised shelving system.

For me, it’s also interesting to what extent the shelves can be adapted to usage habits, for example regarding load capacity or specific uses such as books, decoration, or electronics.

You can easily change the look of the shelves with a simple color and lighting strategy! 🙂 If your niche is a bit tight, a bright, friendly color scheme helps—not only on the shelves but also on the back wall of the niche, for example with a soft pastel color or even wallpaper with a subtle pattern.

A tip I often give: LED light strips under the shelves or small spotlights at the top create an airy appearance and showcase your items stylishly. 🙂

Also, if two smaller Billy-style shelves fit side by side, that can make the whole corner feel more dynamic than one large unit. You can, of course, also play with shelf heights—varied sizes often look more interesting than everything being uniform.

One more practical tip: Make sure the shelves aren’t placed too close to the floor, as dust tends to accumulate there. A small plinth or wall-mounted feet can help with that.

It sounds like a great project for you—good luck!

Are there any specific tips on which Billy models or accessories work best for niches, or possible modifications that might be helpful?

Billy shelves are modular but standardized—the most common widths are 40 or 80 cm (16 or 31.5 inches), with a depth of 28 cm (11 inches). For niches, the narrower model (40 cm/16 inches) is usually recommended because it fits better into small, confined spaces. The 28 cm (11 inches) depth is generally fixed, as it provides stable shelf support.

Regarding customization: there are adjustable shelves available at different height intervals that you can use flexibly. It is also possible to modify or replace the back panels (usually thin particleboard), especially if the niche’s backing is uneven or textured.

Stability tends to be better in small niches when the shelves are fixed to the wall on at least two sides—this reduces the risk of tipping, particularly with taller units.

During installation, it’s important to use hollow wall anchors if you need to drill into drywall, otherwise the shelves will not be securely mounted.

If space is tight in terms of depth, it’s possible to partially recess the shelf into the niche—using just the side panels as partitioning and expanding access openings with small wooden panels—but this requires some carpentry skills.

In summary: precise measurements, choosing the right shelf depth and width, secure wall fixings, and possibly lighting are the key factors.
