I love those benches I have used one as sewing/desk with trestle legs, love it. The following is my idea with timber bench tops and using your cabinets, This would work if you could run the plumbing across to the left,either inside or externally. ,I have moved the sink to allow you to use the 80cm cabinet as your dish rack, the window won;t allow this. Or you could just swap the sink and cooker and use other shelving for the dish rack Back wall R-L 60cm cabinet,cooker,60cm cabinet 800 void for sink,60cm cabinet.fridge. Wall, using the 80cm x 42cm as plate drainer with timber open shelves on both sides, extraction is a simple ceiling extractor fan. I have added a narrow 60cm Island which uses both 40cm at both ends,like the sink there's a void which can have a couple of stools andr rubbish binscan be placed under the sink cheers

in a similar situation we discovered that it's not legal to convert a shed to living areas unless the original shed was built specifically for the purpose with the floor, walls and roof built to meet A class residential building regulations so we found that is was more cost effective to build an extension so that we now have a small house attached to a big shed but, if you just want to line part of the shed then you'll need some extra wall framing to support the new windows, doors, and gyprock, an electrician to install lights and power, gyprocker to line walls and ceiling and then there will be windows to install, doors to hang, architraves and skirting boards but first check with local council to find out what's legal and you can find step by step procedures on line or at the local library but you'll need extra steel framing and your local steel shed retailers should be able to give you some basic advice and supply the extra framing and recommend a shed erector if you need help with installing the framing but check Gumtree and/or local recycling for second hand windows, doors and recycled kitchen cabinets for storage..

Have you been into the closest timber supplier? Often they won’t have stock on their website, you have to go in and ask.
