Boring repetitive conversation

[diddlededee]

My friend just speaks about their home improvements constantly. If I try and move us to another topic, they'll always bring the conversation back to their house and plans.
If I ever mention anything about my own home (which I do very rarely), they don't engage and change the conversation.

I'm starting to get very bored and it's putting me off hanging out with them.

They are only like this with me as when we are with other people they don't mention their home improvements.

How do I get them to stop talking to me about this without affecting the friendship?!
(They used to be good fun to chat to but now it's quite boring just talking about their house).

Of course it's not because you continually talk about some topic that they are not interested in?

Who was it who said a bore is someone who talks about themselves when all you want to do is talk about yourself?

You could try saying 'please stop talking to me about home improvements', but, if they either haven't got any other topics of conversation, or they get pissed off at you for asking, you won't have to hang out with them any more, which would be a result, wouldn't it?
