I kind of like the simplicity and sparseness of it, but I also think it looks like they just couldn't be arsed to finish it off, and I think that's probably what your visitors are likely to say too!
What's moisture in the air and spills on cabinets going to do to all that wood? Is it treated to the extent that they just wipe off? What ongoing maintenance would those surfaces require to make sure they're always washable?
Idk what house prices are doing in that part of London, but new builds are generally overpriced by up to 10%, so if your local house prices are stagnating or falling and you know you might need to move within 5-10 years, proceed with caution. It could be quite some time before you even break even, if those are the circumstances in your area.
I'd be less likely to say this if it looked like an easily sellable new built family home, but it doesn't. It looks like an eco-warrior's City bolthole :)
Pls don't take offence. I do quite like it.
