Hi Nikhil. What's the actual colour of the cream paint so can attempt to find a granite although it is hard online as colours show differently. I'd also keep upstands in the granite and maybe even the splashback for a clean look. I'm not a pro hence take my comments accordingly (!) and I know you didn't ask for layout advice so I hope you don't me saying but I'm not sure if the sink is in the most practical position as you can't stack dishes next to it etc. I'd also check the safety regs for a gas hob so close to a window as it may potentially be dangerous if the window is open. I'm also not sure where the fridge freezer is in relation to the rest of the kitchen?

I'm guessing by the layout, and fireplaces that it's an old Victorian building. The only thing to remember with flats is that unless you are the sole Freeholder as well as the leaseholder, then you have to get permission from the Freeholder for just about anything internally with regards moving / knocking down walls. I would say, that the best thing to do would be to have a small archway from lounge ( bed 2 ) in to the kitchen diner. The next owner can easily re-instate the wall if they want 2 bedrooms back.....................obviously 2 beds is more valuable than 1. Moving the Kitchen to the bedroom is a better idea and should be achievable as there is clearly drain access out the back near the toilet. If you were to do that you end up with a great sized lounge / diner in the biggest room. You have to take the advice of a structural engineer though, due to it being a flat as you need to know what's structural. I personally nearly always run things past a local estate agent to confirm that my changes are going to add value. I would imagine that a large / spacious well layed out one bed is going to be similar in value to a cramped 2 bed.

I think it will be difficult to find something to match. I could be wrong but, from the photo, it looks like the drive was some kind of crazy paving made up from broken slabs - 2 or 3 different colours (?) which have since weathered & faded. So if you found something similar to replace them, the colour would most likely be brighter. What happened to the parts of the drive that the builder took up?

As others have stated above, the gas hob arrangement just isn't safe and it needs to be ideally 300mm from the edge. That would be the first thing i'd resolve before worrying about new hobs. I think you're looking at a new worktop for the island then depending on the base units and any built under appliances you could then have a new hob safely fitted. Most hobs upto 750 wide have a 560*490 cutout, 800 and above need a bigger cut out. The other issue you may have with a large gas hob is the gas supply pipe could be undersized for the new hob and your gas man might refuse to connect it. Induction hobs are brilliant but you do need suitable pans to use (and no one with a pacemaker). If you're worried about loosing the gas you could go with domino hobs, basically these are 300 wide hobs which have joining strips so you can make your own hob design and combine different cooking methods, not the cheapest hobs but could be more functional for you.
