ᐅ Is it possible to extend IKEA Brimnes furniture with custom-built add-on components?

I would like to know if it is possible to extend the IKEA Brimnes furniture with custom-made add-on parts. Specifically, I am interested in whether the construction method and materials of the Brimnes system are stable enough to support additional shelves, upper cabinets, or other elements that are self-made or customized and mounted on top. Are there any experiences regarding the connection points and whether the furniture can be safely extended without professional workshop equipment? It is especially important for me to know if the assembly can be modified in such a way that the furniture remains stable and maintains its load-bearing capacity after the extension.

Yes, that is generally possible. It is best to reinforce the connection points with additional screws or metal brackets. Make sure that the attached parts are not too heavy.

It is important to make the connection stable. IKEA furniture is often assembled using dowels and clamps, but you can also use screws in addition. Just be careful with the drill holes to avoid them tearing out.

If you want to build extension parts yourself, I recommend using wood or panels that are similarly sturdy and at least the same thickness as the original. Additionally, the attachment should be made not only at the back wall but also on the sides to prevent tipping.

Brimnes joints are often designed to be connected with glue, dowels, and screws. If you expand it yourself, do not overestimate the load-bearing capacity. Reinforce with metal brackets and screw into load-bearing parts, such as the side panels. This is more of a DIY project.

Thank you for your suggestions. I am also interested to know if anyone has practical experience with attaching custom-built add-on units to Brimnes dressers or cabinets. How did you address the stress points to prevent any movement? And how much weight can these constructions support? Would it make more sense to place a second dresser on top and simply connect it, instead of using an add-on unit?
