Hi OP, I see you've taken the house off the market now, but I'd like to comment still.
I would be very wary of installing a brand new kitchen. I've not bought houses in the past because a new kitchen that I've disliked has been installed and I think it's a waste to then rip it out and redo it, but then neither could I have lived in a house with the new kitchen. So, simple solution is to look elsewhere.
I actually like your kitchen units, what I don't like are the beige tiles, so if I bought your house I'd keep the kitchen but get rid of those tiles and put in more colourful ones. (In one house I sold, it was very old fashioned with very dated tiles that I painted to freshen them up. With other very cheap measures, I turned the house from being unsaleable to having two at offer price offers on the first day I put it back on the market.)
The same with the bathrooms. Kitchens and bathrooms are so personal. Perhaps completely modernise one of them, the principal ensuite, and with the others put in different blinds or something to give them a brighter feel. I also agree with comments about there being a lot of yellow in your house. Are there any other colours you like that you could buy accessories in to make each room look a little different. I'd perhaps update the curtains/blinds in the sitting room (avoiding yellow). Have you thought of hanging a few more pictures as the walls seem quite bare?
Everything looks a bit samey and clinical. I suspect that's because you've hidden everything! Please get your books back out, and a few toys. The baby's room feels particularly odd, as if there's no baby at all.
What I suggest with the garden is that you employ the services of a highly recommended professional landscaper. I know you have dogs so I'm not suggesting anything complicated. But they will know best how to create a sense of more distance between you and the other properties. This seems to me where money will be well spent. No one is going to rip out things that suggest a spacious yet secluded garden. Which yours isn't at the moment. A good landscaper will know all sorts of tricks to turn around the rather (again) clinical looking garden, and it'll be a lot more succesful than planting a couple of acers in the hope they'll sort out the problem. Randomly planting trees where you think they'll hide next door isn't always the best solution.
When you relist, I'd have fewer photos of the same things, forget pointless ones (like the house name), and get into the house in pic 2.
Good luck!
