Not read all posts so sorry if i have repeated
The front looks a bit boring (Sorry), paint the fence and tame the lavender. Add some planters or pots to give it some colour. Have a drive round your estate and see what other have done for inspiration.
Remove what you don't use all the time from the kitchen counters. You can put the toaster away and the bread bin and move the microwave to where the bread bin is now - if there is a plug? The more free space the better, can you put air fryer/coffee machine in a cupboard and just get them out when you need them?
The fridge - would this go in the cupboard you walk through to the downstairs loo? Or on the opposite wall behind the door? Can you move the coats and shoe to somewhere else? I would be inclined to make that area just a dining area - with a larger table and 6 chairs
The bed looks like it back to front and the curtain bit should be a headboard - are you able to turn it round - it looks odd, how do you see the TV on the wall over the curtain bit?
The lounge you face away from the window - I would move the furniture around so couch is on the blue or white wall to maximise space
2nd bedroom, again can you move that bed onto the wall to the right so there is space down both sides of the bed?
The office in the 3rd bedroom - is this used as an office? Or could you condense it down to one desk and put a small single bed in there?
Love the colours and the back garden is bright and inviting
