ᐅ Are there any practical tips for expanding IKEA Hemnes shelving systems?

I would like to know if there are practical tips and tricks for expanding the IKEA Hemnes shelving system in a sensible and functional way. Specifically, I am interested in options for increasing stability when stacking multiple units, alternative inserts or shelves that are not offered by IKEA as standard, and advice for adapting to spatial challenges such as sloped ceilings or recessed areas. Are there tested extensions or DIY solutions that make storage space more efficient without significantly altering the original design? I look forward to firsthand tips or recommendations that you have personally tried.

Hey Danijel59, that’s a great question. Hemnes is really a solid base system, but yes, there’s definitely room for improvement! 😄

Regarding stability: a classic solution is to secure the individual shelves to the wall using brackets – this completely prevents any wobbling. You can also fasten the shelves together vertically with metal connectors so they function as a single unit and don’t come apart.

For the shelves themselves, there are some clever options: for example, I often insert thinner MDF panels when I need more small compartments or want to store accessories. You can also cut acrylic dividers yourself – they hold up well and look modern.

If you have sloped ceilings, a narrow shelf door or converting shelves to open compartments is worthwhile to use the space flexibly. I once built modular systems using wooden slats to create adjustable compartments – that worked really well.

It sounds complex but really isn’t that bad. Try screwing things together with brackets first; that already makes a big difference! ✌️

This is indeed the most important step when expanding, otherwise the whole setup quickly becomes unstable, especially if you stack multiple units.

In one of my projects, I combined several Hemnes shelves vertically. I also used special metal connectors designed specifically for stacking furniture between the units. It’s also important not to use screws that are too short, as they can pull out of the wood.

For sloped floors, I made custom wooden wedges to level the shelves. These can be color-matched by laser engraving or painting.

Additionally, I recommend sticking to shelf dimensions of 40 x 35 cm (16 x 14 inches) for custom inserts; these sizes are compatible with most add-ons and replacement shelves from IKEA or third-party suppliers.

If you like, I can also put together a list of the best sources for additional hardware fittings.

Do you have any specific rooms that require even more flexibility?

Thank you for the detailed answer! Yes, I actually have a sloped ceiling in the living room where I want to place the Hemnes shelf. The slope starts at about 150cm (5 feet) high and then slopes downward. I’m mainly looking for advice on how to adjust or arrange the shelf components so that the top surface aligns as closely as possible with the slope, or at least follows the slope in a stepped fashion.

I’m also interested in whether modular adjustable shelves are worthwhile for flexible use, or if it makes more sense to use fixed individual boards here.

I would be very grateful if someone could suggest a practical solution for dealing with the sloped ceiling.

Hello Danijel59,

Sloping ceilings can be quite challenging, but with some patience and adjustments, it works out well. For a flush finish, it’s advisable to cut the top shelf individually—preferably with a band saw or jigsaw—depending on the angle of the slope.

Another option is to combine several separate shelving units with different heights to create a “stepped” system that follows the slope. This way, you can use various heights for storage, which also creates an interesting look.

For modular shelves: they are definitely more flexible, especially if you want to change the contents regularly. You can easily adjust the compartments. Fixed shelves, on the other hand, provide more stability and often carry weight better.

If you need a construction guide or measurements, I’m happy to help calculate the dimensions accordingly.

If you can provide the exact room measurements, that would be ideal. This way, we can better assess the possibilities.
