How to attach end panels to a built-in wardrobe

[skön]

Planning to build a wardrobe 1800 mm wide and 2400 mm high with sliding doors. Regalux sliding doors are purchased. The wall behind already has drywall and shelves mounted on a support rail inside the wardrobe. The baseboard has been removed. The depth of the wardrobe is intended to be 500 mm. My question concerns the sides regarding material and attachment to the existing drywall to make it sturdy.

One can use an MDF board, etc., which can be fastened with furniture angles to the wall and ceiling and/or floor.
I see that Elfa has a side panel wall made of chipboard with white melamine here: https://elfa.com/sv-se/produkter/skjutdorrar/tillval/sdsidepanel

You can have an MDF board, etc., that you attach with furniture brackets to the wall and ceiling and/or floor.

Thanks for the response, but Elfa's side panels have the wrong dimensions. The floor is concrete, so it's difficult to attach there. Need to look into furniture brackets.

Elfas was an example so that you could see a type of board that works, I didn't mean for you to buy those specifically. It's certainly fine to drill into concrete, many houses have concrete walls.
