ᐅ How can I expand the IKEA Platsa modular system?

Hello everyone,

I am currently working with the IKEA Platsa system and planning to expand my existing storage modularly. Since the Platsa system is known for its flexibility, I would like to ask for your advice on the best way to integrate additional elements as simply and securely as possible.

I am particularly interested in – whether you use proven combinations or expansion strategies, – which mounting options for module connections are recommended (especially in corners or angled arrangements), – which combinations of fronts and depths work well together without compromising stability, and – if you have experience with accessories like shelves, legs, or back panels that make the system even more versatile.

I want to avoid the construction becoming wobbly after assembly or excessive waste materials. Does anyone have tips on planning or practical implementation?

Thank you in advance for your well-founded experience and suggestions!

That’s a good approach. For modular expansion of Platsa, I recommend first accurately measuring the available floor space and considering whether you want to expand more in width or height.

- Platsa modules come in different heights (64 cm (25 inches) or 128 cm (50 inches)) and depths (35 cm (14 inches) or 55 cm (22 inches)). For stability, it’s important to pay attention to the combination of depths, for example, avoid placing 35 cm deep modules next to 55 cm deep ones without proper framing.
- Assembly is fairly flexible. Essentially, the modules connect using plastic connectors and screws. To create angled sections, corner kits, which IKEA sells separately, are helpful.
- I would also recommend installing feet at the bottom, which IKEA offers separately. This ensures the modules stand securely on the floor and are slightly elevated, helping to prevent moisture buildup.
- For fronts, I suggest using the same surface finish on adjacent modules. This creates a more cohesive look and usually helps the doors close better.

Do you already have a specific idea whether the expansion should be, for example, in an L-shape or as separate modules built on top of the existing setup?

Basically, I recommend considering the overall load. Platsa modules are stable, but stacking several tall modules or installing them unevenly can cause problems.

- For corners, it is often best to use a corner element or set up two modules at a right angle with corner brackets to prevent twisting.
- Make sure to securely fasten the back panels completely; this provides significant stability.
- I have had good results using adjustable shelves, especially in combination with different front types (e.g., doors, drawers, open shelves).
- For depths, I recommend choosing as uniform depths as possible, since varying depths are possible but often lead to issues with both appearance and stability.

Expansions should be carefully planned using the IKEA online configurator, where you can also check door swing directions and possible collisions.

For the extension, use sturdy angle brackets or mounting plates to connect the modules.

Also important: Fully screw and secure the back panels; any gaps can cause instability later.

If you want to save space, use the 35cm (14 inches) deep modules in tight areas.

I fully understand that the most important aspect of your extension is its stability. From my experience, it can actually be helpful to build an additional stabilizing frame yourself, especially if you are planning unusual shapes.

What I also like to do is combine open and closed modules, which creates a more spacious feeling, but open compartments should always be securely fastened.

Another option is to screw individual modules to the wall. This makes handling easier and provides a greater sense of security.

Is there a reason why you prefer not to add more modules in length or width instead of height? Often this helps reduce the risk of tipping.
