We spent around £25k which included knocking down a wall and putting a rsj in, vaulting the ceiling in the adjoining dining room, velus windows, plaster boarding, skimming throughout, new electrics, light fittings, paint, new solid oak skirtings, door and window furniture, flooring, range cooker, dishwasher, sink, taps, bar stools, composite island top, wood worktops, relocating plumbing and fitting new radiators, new stop tap, tiling and kitchen units. That was all labour and some bits of furniture too. The kitchen units were from DIY Kitchens and cost around £8.5k - we had to pay for the top delivery as access is awkward.
We could have done it for less, but decided not to skimp as we got to the end of the work as it would have been a false economy. HTH.
