Electric fireplace (pay attention to depth and weight of fireplace unit. And make sure it can be recess mounted. I used the Tangkula 36 Inches Recessed Electric Fireplace because it only used 3” in depth and weighted only 33 lbs.)
I butted and fastened 2 BESTÅ double frames together. I finished the two ends with doors. Behind the doors, shelves for storage.
Then I modified the 2 center cavities to accommodate the built-in fireplace.
I used the low drawer and mounted it to door front (used cheap drawer front to figure hole spacing). Drawer is mounted on slides at bottom of cabinets, the 2 doors and drawers are joined together with mending plates.
Once I received the fireplace I did measurements and made following cutouts:
Both drawer units needed cutout to compensate for fireplace depth.
Center frame panel needed cutout to compensate for fireplace cutout.
Door fronts cutout opening for fireplace.
Mount 2 drawers to door fronts, join them together and install on slides.
