You have a lovely home, your photographer has really let you down. The pictures are terrible and I’d get them redone before your house goes stale on the market.
You need to open all your curtains and blinds and flood the rooms with light, even then turn your lights on... create a bright airy space.
The picture taken from underneath the stairs, I truly don’t know what they are thinking with this! It needs to be taken so the stairs don’t dominate the room, even a Birdseye view off the stairs would be preferable to this.., the room itself is lovely, personally I wouldn’t hide your lovely fireplace with the coffee table as it’s a great selling point, you could even light it for pics.
Your room with the blue couch, definitely make this your dining room. Don’t waste money taking the fire out if you want to move, put a big bunch of fresh flowers on it. Have the picture taken from the other side so the fireplace isn’t in the shot. When you get a dining table in there the fireplace with not be the focal point.
Personally, I would create a family style room with your conservatory. I would buy a large rug to cover up the floor (again...don’t touch it if your moving) I would go for a rustic cottage feel, tie the floor in like a feature. Sofa, Tv and toys- the illusion of a family room and a ‘best room’ will attract families with young children enduring the death by plastic phase!
Mow the lawn, tuck the patio set in, move the bins, pot some pansies and get the estate agent to come back on a brighter day.
Your very main issue is your pictures tho, they are shocking and will most definitely lose you viewings. Your home is lovely- be assertive with the estate agent, they are not marketing your house to it’s full potential.
Good luck!!!
