order from the company u got it from in the first place? or get professional help. probably gonna cost 300 min to replace laminate.

Shelves misaligned? i assume ping shui not good? No. Not suppose to be so. Laminates has bump on edges? abs edging? No. Holes? screw holes or for hinges? The doors are normal plyboards without holes. why would there be extra holes?

"For the kitchen, is it possible to have an island & washing area without cramping the area?" nope no way at all unless ur kitchen island encompasses ur stove and sink as well

no idea on gas cylinder heights, but u could hack away part of the plinth and make a opening below the kitchen cabinet. just a thought. and if you are using solid top, i will be about 38mm

go to a industrial park and find any carpentry company and ask them for a quote. some companies may not be willing to help on a small project but some might.

Hollow wrought iron gates go for minimally 300-400+ for a standard design one. Factoring the cost price and labour, it is doubtful it can go any lower. As mentioned, if u have the moolah u can always go ahead and get a solid wrought iron gate, those are usually customizable with decorative pieces from italy though expensive as ****. Good quality wrought iron paint also come at a ridiculous price. Last i heard a small tin of gold paint cost upwards of $80+, not too clear on this though as im not in the wrought iron business.

if you decide to diy it, a good option would be to get marine ply. though it is 2-3x more expensive, its a good investment

find laminate companies bring down the door, ask them to do abs trimming for you. will not be that expensive.
