I agree with chloe, more drawers is better (so I prefer b) and the wall units on the hob wall can be removed.

If you need more storage, you could add wall units all the way along the hob wall, and have the vent hood hidden in one of them, so it just looks like a run of wall units. It would look much nicer without anything there though - shelves look nice, but you've got to be happy with cleaning them. I'd hang some art instead of shelves - provide a focus that isn't the vent hood.

Given you've got loads of worktop space, I'd be tempted to look at full-length cupboards for the whole of the oven wall - one double unit being drawers on the bottom and a pantry cupboard above for hiding small appliances from view.

Having stayed in a house with a very similar layout I would suggest having another cutlery drawer near the kettle…if someone is cooking at the hob its irritating to ask them to move if you need a spoon or want to lay the table.

Personally, I would swap the sink and hob as sitting on a stool, and/or eating overlooking a sink is off putting….but perhaps a small rinsing sink at one end?

I would also consider bringing the peninsula edge in front of the pillar to give you maximum liveable space and consider having ‘dead’ corners to avoid awkward corner cupboards

I agree with putting in as many drawers as you can and a shelf rather than cupboards.

I would remove the wall units on the cooker/extractor end completely. You could have a shelf incorporating an extractor or in line with the bottom of the one shown (extractor). I would take my worktop up the wall to the underside of the shelf and you will have the easiest kitchen in the world to clean. I would also suggest a waterfall edge on the end of the peninsula to avoid having the sharp worktop edge sticking out as it is currently shown. Your bar stools would also look neater as they wouldn't be so visible. Example of waterfall edge worktop.

Great suggestions thank you all! I will have a look and make some alterations

I’d ditch the single unit on the right. It feels a bit like it’s there just to fill space. Open shelves or even nothing would make that end feel lighter, especially since storage doesn’t seem to be an issue.

In general, I'd either lose the wall units on the hob wall or add more so they come closer to the extractor, depending on ceiling height you could opt for taller wall units/towers and infill to the ceiling. I'd avoid wine racks and open shelves as they get dusty and greasy when up high.

Looking at the 2 plans, i'd combine them, the oven tower run on option B works better than option A, I'd change base/wall units to 900 and 450, you could also change the 900 hi line to a drawer unit as well.

The hob run on option A looks better, you could change the drawers to 1000 wide so the corner doors are 450 wide [match the other base doors].

The sink run in option B works better, dishwashers in corners aren't great, cause a mess and have limited access, you may also need to run the sink waste to the boxing if the soil stack is there? so i'd have a 450 hi line/drw line [if you want an extra cutlery drw] then the 600 sink, 600 dishwasher and at the end the 450 bin.
