Given a relatively small area to install a cupboard I turned to the IKEA catalogue. The floor area available was approximately 1 metre wide by 28 cm deep. It so happens that standard Billy bookcases are 28cm deep but they only come in widths of 80 or 40 cm, so I ordered an 80 cm one and added a 20cm Gnedby shelf unit. Both units are 202 cm high.
Although the shelf unit is much shallower than the Billy, this meant I didn’t have to worry about the inside (RHS) corner.
I also ordered two Bergsbo doors, each 50 cm wide.
Having built the Billy I turned it onto its side and attached the Gnedby as I built it, hiding the joining bolts and screws below the base and behind the fixed shelf and top. This didn’t add much to the total weight so it was still quite easy to handle the whole assembly.
I screwed a batten to the right hand wall to match the thickness of the skirting with some packing behind to compensate for the wavy plaster and used decorator’s caulk to seal the gaps. Pre-cut cut outs in the Billy meant it could be pushed tight to the back wall without a batten, with the shallower Gnedby unit also giving plenty of clearance behind.
The only issue was with the doors, which are routed to take three hinges – the middle one of which clashes with the fixed Billy shelf. The doors are not heavy and two hinges are adequate but other doors are available with the middle hinge offset to avoid this potential problem. I drilled the Billy bookcase to fit the hinges, and used one self-closing and one cushioned hinge on each door.
The floor has a distinct slope from right to left and I used a 1.5cm batten (painted white to match) under the left hand end to compensate and keep the whole assembly vertical and aligned with the right-hand wall. Being on a carpeted floor means the gap at the bottom isn’t obvious.
I had some small door knobs that suit the confined location, so I drilled 5mm holes and used those. The end result is very neat and the customer (my mother-in-law!) is delighted.
