ᐅ Are there options to expand IKEA Hemnes shelving units?

Hello everyone, I am currently looking into whether there are pragmatic and practical ways to expand or modularize IKEA Hemnes shelves. I already own a Hemnes shelf and am considering enlarging it either in width or height without having to buy completely new units or switch to a different series. I am especially interested in options that remain structurally stable and preserve the appearance—such as additional side panels, matching extension sets, or alternative solutions using compatible components from the IKEA range or third-party suppliers. Does anyone know of specific options, experiences, or tips on how Hemnes shelves can be effectively extended to adapt them individually to changing space and storage needs?

Hello Gujeda, Hemnes shelves are unfortunately not specifically designed for extensions. The easiest way to expand them is by placing another shelf unit from the same series next to it and fastening them together. For more height, you can choose a different taller model or adjust the individual shelves flexibly.

I understand your concern well, Gujeda. I felt the same way because I wanted to customize my Hemnes shelf and found it frustrating that the options are quite limited. It’s noticeable that the fixed dimensions and design leave little room for flexibility. However, I experimented with DIY solutions, such as wooden extension frames that you cut separately. This takes time and effort but is worthwhile in terms of appearance if you have good craftsmanship skills. How about you—have you considered any self-build options?

In practice, there are no official extensions from IKEA for Hemnes. Extensions are only possible by placing identical shelving units side by side or by combining different IKEA models. Self-construction is possible, but it quickly becomes complicated.

Just a quick note: Hemnes shelves can be placed side by side and screwed together with brackets. There are no additional modules for extra height, but the shelves can be adjusted if the pre-drilled holes allow.

I find your question very relevant, Gujeda, as such shelving systems often reach their limits when you want to stay flexible. Depending on the situation, I have implemented mixed solutions using Hemnes and similar IKEA models. I connected them with wooden slats to create a cohesive look. In my experience, well-matched extensions usually come more from creativity and craftsmanship than from an official expansion solution. Do you know the construction tolerances, meaning whether the manufacturer allows some flexibility?
