I could do with a rough idea of floor to ceiling cupboards, 2m tall and 1.8m of space, likely 4 opening doors. I expect it would be cheaper to ask a joiner to make out of ply/mdf than pay for kitchen units?
Not a joiner but I have recently fitted my kitchen and am in the planning stages of making cabinets for the chimney alcoves in my living room, similar size.
Cheapish ikea/wickes cabinets probably cheaper than the joiner, if you can fit them yourself and they make something to fit. Ikea widths are 20/40/60/80, wickes do 50/100s.
FWIW I’m planning to build in cupboards with bookcases above in 2 alcoves, about 1.2m wide each, 2m high ish, and I reckon it’ll swallow £300-£400 of materials (I already have tools), plus making the things. It’d be about that per-side to make out of kitchen cabinets (though much quicker to assemble, wouldn’t fit for me), and I reckon it’d be about double that per side to get someone to do it for me.
So footflaps 1k sounds reasonable.
