As part of our kitchen reno, we extended a portion to the edge of the wall.
This left a gap between the ceiling and new cabinets so I had to build an extension to the bulkhead.
16mm melamine boards
55mm cornice
Ceiling paint
Wall paint
Construction adhesive
Mitre saw
Mitre box
Hand saw
Stanley knife
Chisel
Hammer
I removed parts of the cornices at the edges where I planed to extend them only (no photo) using a chisel and hammer.
I built a three sided frame including a base that attached to the upper side of the cabinet below. This aligned with the existing wall and bulkhead.
I then cut some pieces of cornice to size using a mitre box and hand saw and glued them on using construction adhesive.
I also applied some plaster to tidy all the joints up.
Then I taped the wall and ceiling sections and painted them separately.
Completed the paint work and the bulkhead and cornice look like they've always been there.
Great work, @diy_hausdesigns! You certainly solved that difficult situation.
Many thanks for sharing the steps you took, as they will greatly assist anyone in a similar situation.

Hello! This post may be a bit old but appreciate you sharing this! I plan to tackle a bit of a 60mm cornice addition to my cabinet. May I know what mitre box did you use? Thanks! Not sure if https://www.bunnings.com.au/craftright-305mm-mitre-box_p0492186?region_id=116042&gad_source=1&gclid=... can help as im totally new to mitre-ing cornices with no experience.
Hi @ScottR,
Allow me to tag @diy_hausdesigns so they are notified of your question. Hopefully, he will respond soon.
Any mitre box should be fine and the Craftright 305mm Mitre Box is a great option.
If you don't already have a saw to cut your cornice with, this Craftright Mitre Box And Saw Set is also an option worth considering.
Let me know if there is anything else I can assist with.
