I would prefer a detached to a semi- detached, (surely most people do???) But there are exceptions. eg, we are in a semi now, with a huge garden (end plot) and a view over the hills and woodlands, from the front and moreso the side... Not overlooked either, and elevated, (5-6 feet above the road.) It has a 4 car driveway, and a garage.
A detached property 6 doors down (same size as ours) came up earlier this year, and DH said 'shall we go for it'? but it has a garden that is around a third of the size of ours, a shared drive, (fits 2 cars, so 1 for each property,) no garage, and not elevated as the road goes downhill. No view to speak of, and overlooked back and front. The 'front' door is at the side, and when you come out of it you are facing next door's 'front' door. Just 2 car widths away.
If I could have our exact plot - and make the house detached - I would, but we have too much to give up. I love our elevated, not-overlooked, big 'end plot' overlooking the woodlands. Also, our neighbour (joined on) is a young mum with one child, and her partner. We hardly ever hear them. They are very considerate, and never play loud music. The little girl is quiet too, and her bedroom is on the other side of the house, so we never hear her in there. We have had a couple of noisy neighbours before she moved in 6 years ago, but we just got a sound bar, for the TV, and a white noise machine for the bedroom. We also get on really well with her, and a good neighbour is like gold dust!
