Description by Gijs

For our renovation of the attic floor, it was a great wish to install a built-in cupboard, extending from one side of the house to the other side of the house under a sloping roof. After requesting a few quotes, we discovered that the costs were high. We gained inspiration through various social media channels and used Ikea hacks, where we sawed and installed existing PAX cabinet parts to size. Due to the existing sloping roof parts, we could not use the standard doors from Ikea. We have therefore chosen to make custom MDF door panels, using the 18mm primed MDF panels from We had this cut to size with an excess length of 10cm and with an oblique angle, equal to the slope of our roof.

How I made this project

The construction steps are as follows:

  1. Placing and measuring the cabinets cut to size;
  2. Ordering the individual panels (future doors) with ten centimeters of excess length at the bottom, using the 'rectangle with beveled short side' to create the correct angle of inclination;
  3. Cut the supplied doors to theoretical size using a circular saw with guide rail (with 3mm clearance from the already installed plinth at the top). Of course, cover the ends of the plates with painter's tape to prevent fraying;
  4. Drilling the recesses for the concealed hinges with a suitable drilling jig;
  5. Hanging and adjusting all doors with the appropriate adjustment screws on the concealed hinges;
  6. Hold the pre-sawn/ordered bottom skirting board on a piece of subfloor and laminate floor (of the final floor) against the bottom of the doors to mark this size;
  7. Remove the doors from the cabinets and set out a new cutting line 3mm above the line just marked. Then shorten the doors with the circular saw;
  8. Sand the doors lightly with 180 grit sandpaper;
  9. Paint the doors with semi-gloss interior lacquer (two layers is sufficient, lightly sand between the two layers with 180 grit sandpaper);
  10. Hanging the painted doors and providing handles;
  11. Final adjustment of the doors.

The end result? A unique built-in cupboard that not only offers extra storage space, but also gives a personal touch to your interior.
