I don’t think you need to do much.
It just looks a bit soulless.
Pic 1 - it’s all about the drive. Retake it from the opposite angle so you can at least see the front door. Pressure wash said drive. Maybe put some colourful pots on it. Moe the strip of grass.
Pic 2 - despite what you say, it doesn’t look like you can open the door. So can you move whatever the black thing is next to the sofa and move the sofa along a bit, so it looks like you can open the door.
Maybe a more colourful rug. The grey one is a bit insipid. And some chunkier cushions to detract from the big black sofas. Maybe red, as that seems to be theme in this room. Clear the mantelpiece.
Kitchen / diner - get rid of all the kid’s stuff and the cat scratching post. And is that a random bit of carpet? Get rid of that. Get rid of all the clutter on the sides / from the top of the fridge / on the fridge.
Bedroom one - remove both chairs, black thing at end of bed, thing behind one chair (is it a hoover?). Maybe put bedside tables next to the bed. Take another picture too, from a different angle. I have no idea if this room fits a wardrobe etc...
Remove red thing on bed.
Bedroom two - reposition bed so headroom is against the wall with the plug sockets on. Get a plain white duvet cover and pillow cases, so it doesn’t clash with the curtains.
Bedroom three - just straighten the duvet.
Bedroom four - maybe put one of the white chairs removed from bedroom one in here, given all the other furniture is white.
En-suite - remove can of glade and straighten towel
Bathroom - remove all shower products, bath mat and towel. Can you get a new white loo seat. Maybe a few fake plants just to add some colour in there.
Garden - paint fence if you don’t want to replace it. Mow the lawn. Get (borrow) a patio set for the patio.
