I so agree with Alphen Construction - on first glance, it is definitely the handles that are drawing the eye to changes in height. I would definitely try Alphen Constructions' suggestion re 'blocking out the handles with tape' to see how you like the effect. Take a photo when you do it, you can then compare. I think I would remove the handle from the cupboard over the fridge and the cupboard over the stove. I wonder if a steel extractor fan that would take that cupboard to the same level as the other cupboards might be an effective trick, it would also tie in the steel of the fridge, oven and appliances. Under cabinet lighting is needed in my opinion. I do hope you will be able to enjoy your kitchen because it is lovely. I wish you all the best.

you can buy an additive for paint that slows the drying down on water based gloss/ semi gloss paint. We have painted the back of our island with same problem. waiting for weather to cool down before we redo.

Part of the appeal of the cupbaords in your photo is that the clever cabinetmaker has used real timber, possibly a timber veneer, to grain match the doors. This means that even though are a lot of doors the timber has come from the same tree, and the grain pattern is continuous across the doors. Not all kitchen cabinetmakers have this level of craftsmanship and such a good eye for detail, and such craftsmanship comes at a price. The products that you mention are good imitations of timber grain, but like a wallpaper have a "repeat". This means that it is next to impossible to get grain matching across doors. For some people this doesn't matter, but some people find mis-matched timber grain really annoying. You need to decide what type of person you are, and decide to spend big, or look at other options... The photo is of some mismatched, timber-look doors.

Its going to stick out no matter what you do. Is there no budget to reface the cupboard doors and drawers? My Only Suggestion is to not do a White Gloss and instead use a Ravine laminate or a totally different colour and use the colour somewhere else in the kitchen like the off cuts for a frame for some artwork. Or on the kicks. If its going to stick out, and it will, then go all out. The next best option is go to a joinery company ask if you can take some off cuts out of the bin, make a temporary shelf and save up so you can do everything at the one time. If you redo the kitchen you will end up redoing that cabinet to get a consistent colour. Even with colour matching there is still slight differences because one is new and the other is old.
