Firstly, be patient! Things don't tick along as quickly as you would possibly hope.
Yes, I believe the air is cleaner- even if it isn't, you are close to the sea, trees and quiet.
Regarding boundaries etc, most of the agents up there refer you to a solicitor who is familiar with village houses and the nuances involved. Saying that, we bought our house and it may look like the solicitor got it wrong and we are the proud owners of a slope!
I'll give you the agent we went through but I wouldn't recomend the solicitors we went through, for various reasons even though they are very big and have offices in Pacific Place.
