Detached vs Semi detached

[Finsburyman]

Hi all, We are about to purchase a new house to the south of London and I am really struggle with our two choices. I think we would purchase one of the two properties for sure. Both houses require alot of work / modernisation and we plan to extend both in the same way with side and rear extension. Both have an existing garage that I plan to convert to a side extension.

Detached house - 1930s, 3 beds two large reception larger rooms, smaller garden at 80 feet, Price £550k

Semi detached - 1930s, 3 beds, one long but narrower joint reception, smaller rooms, larger garden at 150 feet. Larger plot in general. Slightly nicer road. Price £520k.

We are really torn about which one to go for as they are both near stations, outstanding schools. Is it worth going for a smaller plot but detached house?

Which one would you go for?

Detached. But if I was as 50/50 as you seem to be, it could come down to the position of the vendor - are they in chains? In a hurry to move or likely to drag their feet? Will they move into rented?

Also intrigued about the general area of this place with affordable detached houses and outstanding schools in south London...

One question for you. Does noise bother you and how much?

I'd also prefer detached from the point of view of being considerate about the noise we make disturbing others.
From when the dc were little, through teens, to my now adult dd who likes to come down and play the piano for 20 mins or so before she goes to bed. I wouldn't want her doing that if our living room share a wall with next door.
