Whilst you've put the work in, it's all cosmetic and nothing tackles the issues with the functional layout. If I wanted to make this a family home I'd already be stacking up the big money thinking of all the changes id want to make....
The fireplace is in a stupid position. I'd tear the whole this out. Turn the stairs the other way and move the toilet to under the stairs.If you can build a side extension to make a nicer entrance, great. You can then divide off the bedrooms and family bathroom to make a downstairs "kid sleeping" situation. This can also give you some more storage space.
The utility is a bit redundant. Like a giant corridor of nothing. if you shortened it and made it more of a laundry room this would be more useable. It makes sense to still keep access to the garage though. If this is a decent space with storage then great. Show it.
The kitchen needs replacing and I'd take down the wall dividing the kitchen from the living space, puting in a peninsula with hob on and turning the rear wall of the kitchen into a wall of oven / fridge etc.
Looks like the lighting is all spotlights which gives me the creeps, id want to sort that out.
Upstairs the eaves storage must run on both sides, could this be transformed with better access from the bedrooms? Also a dormer window on the bedroom with just a skylight would be good, even better if it could be a window all the way to the floor as these rooms feel pokey and dark. Also where would you put wardrobes? You'd end up using one as a walk in dressing room come guest bedroom and treating the whole upstairs like a master with en suite.
As for the garden, I'd want a wrap around patio, some decent fencing and a lawn.Why the hell you'd tear that up I have no idea, grass is better than plastic sheeting .
Good luck OP. For the area and the price I'd be looking elsewhere ....
