I’ve been looking for ages for a smart radiator cover for my hall. This design perhaps cuts down on the efficiency of the radiator, but the look is just what I wanted. I designed it to contain some useful shelves, but it could be made narrower by cutting away the rear of the panels and doing away with any shelves.
I bought a secondhand tall billy bookcase from ebay for £15 (as opposed to £55 new), so it was already assembled. I took the back board off then cut off the top of the carcass 30mm above the middle fixed shelf. I retained one of the cut-off sides (this was used for the top covering shelf of my cupboard).
Next, I needed to create an airflow through the item. So I used a jigsaw to cut part of the front kickplate away, trimmed the shelves to allow the radiator to sit inside the cupboard and again cut a curve on the top undershelf. See pics 653 and 709.
I used the spare dowels from the rejected part of the tall bookcase to fit the top shelf (with a 10mm front overhang and 20mm side overhang). There was a small gap at the back of the shelf to allow further airflow.
Lastly, I fitted the doors (bought new for £70). I also fitted the cupboard to the wall with the brackets provided in the door kits to provide lateral and vertical stability. See pic 753.
