From a downsizer with deep pockets, I would add…
@FTP aerial view is helpful. I suggest that you add that image to the photo pack…it shows that you face onto a lane rather than a street & the good sized garden.
kerb appeal - it does count. When I walk towards the street towards my front door, I feel better if the area around my home looks good & feels safe (e.g. no slippery pavements etc). Do you really have two active house alarm systems? This suggests that the area is high crime & possibly not safe. Remove the redundant ‘biscuit tin’ in time for the next photoshoot. As much as possible crop the photo images to minimise the tatty exterior wall next door & obviously the garage on the other side. A couple of plant pots by the very attractive doorway will draw the eye away from the dark passage way at the side. BTW the passage way is an asset, but the poor condition of the paint on next door’s external wall suggests disrepair, not an issue per se as the houses are detached but it may seem a red flag.
The suggestion the the mezzanine room would appeal to a teen is a good one. For now, I would ‘show’ that with a generous single bed with easy flat access to the bathroom & the upper level decked out as a generously fitted study/home office. Yes, the key word is ‘generous’, plenty of space that can be flexibly used by child/teen/guest. For photoshoot, remove the child gate at bottom of stairs.
The Orangery is lost as a seating area. As you have a formal sitting room, the open plan area is too functional & somehow not capturing the flow into the lovely garden. I suggest that you bring the sofas into what is the dining area to become a ‘snug’ with telly AND position the seating so that the open door from the good sized hallway has a clear view/pathway through to the garden (i.e. not blocked by the dining table) - again with the open spacious feel. Then put the dining table into the Orangery as there is plenty of room for a good sized table & chairs with great views of the garden - you may need to play with some awning or shading for the fiercest of summer days but you gain a greater sense of space & natural light.
Kitchen - a few things that niggled. Where is the task lighting ? The natural daylight & windows are very appealing but how can I see to chop etc in low light/evenings? Yes, great to have room for a good sized range, but how can I see what’s cooking at the back? How can I safely reach there? How can I keep the brick clean, where is the wipeable splash back?
Were I a buyer, unless that is period listed detail, I would be planning to render over the brick & wire up for light task lighting or remove the brickwork . As a compromise to sell, maybe considered tiling the inside/around around the hob to reflect some light & for easy maintenance.
It is a lovely house, enjoy it whilst you are there.
