As I’ll be installing sliding doors on my new European laundry, I need to extend the side wall forward by 12 cm to provide space for the door tracks. This wall is 10cm wide.
initially I had thought I could just attach a timber post - but the only size close to what I need is only 900mm x 900mm - so just a couple of cm short.
(I’ll also need to extend the top lintel)
Any ideas how I can do this? I really don’t want to have to build out the frame & attach plasterboard if I can avoid it.
