G'day,
First time posting.
I'm replacing our old built-in double oven, and the new one will leave a 270 mm void above it.
I've attached a photo of the cavity, which is currently open into the roof space. I'd like to seal the top of the void first, then turn the remaining space into a floating shelf/niche like the inspiration photos I've attached.
My plan is then to use the remaining space to build a floating shelf or boxed-out niche, similar to the inspiration photos I've attached. I'd like it to look like it was always part of the cabinetry rather than an afterthought.
My rough idea is:
•Cover the top of the void with cement sheet.
•Leave an appropriate ventilation gap above the oven (around 50-55 mm) or is that not really needed?)
•Build a floating shelf to create a decorative storage nook above the oven.
Does this sound like the right approach, or is there a better way to do it, and is there anything I should be mindful of regarding heat ventilation?
