Let me start by saying that I really like the bold pop of colour that I see on the GF, might not be to everyone’s taste, but really cool! - and I’m the boring millennial grey/beige type of person too!
Now I’d generally say it always comes down to price. A few ppl upthread mentioned is overpriced for the area, haven’t looked, so not sure.
However, I can say your house has a few features that would put buyers significantly off…
n.1 the kitchen!!!!!
I can understand the logic of why you turned the galley into that, but it would have worked significantly better if you either had a galley with a table at the end, or a L shaped kitchen.
you have no wall space, no space for the usual gadgets like coffee machines, toaster, kettle, air fryer, etc.
it all feels really cramped in the middle. This type of island is usually accompanied by another set of kitchen units on the wall. This unfortunately will be unappealing for a lot of people, so price comes down to it even more as it needs to compensate for the unique design as unfortunately you’re not in a boho area of London.
Then something else that’s not working in your favour is the no separate entrance directly into your living room. You have to go through that really long hallway all to walk back to the living area. Sure, it means you can use that wall for the sofa but it really kills the flow and to make it worse the whole room dining and living has carpet.. and to make it worse it appears to be the very low thread that reminds me of carpet tiles of office buildings…
I also believe the images are not great, there’s too many of each room that don’t really add much.
I would actually hire a photographer rather than the EA to take images as they’ll have the experience to make the best of the layout.
Also… if your appliances are hidden in the wall cupboard we see, you NEED a picture showing that so people know there’s a place for them. Many will not see past this.
