Extending boundaries of garden

 Or best case scenario no one cares and they just say move your fence without the mention of money 😂🤞

Best case in the short term, maybe, but might complicate matters if it is picked up when you come to sell that you don't own the whole garden, or if someone does in future turn round and tell you to move the fence back.  Your deeds show the odd shape that matches the current fence?

 I'm still not sure how to approach it with the neighbours. 

Why do you need to mention it to them - it may invoke some greed/jealousy

if the developer currently owns the land & has no issue why can't  they sell it to you before handing over the rest to all estate residents?

This!
