Make sure you are aware of the Party Wall etc Act 1996 ! That can still affect you and your property even if you aren’t physically attached to your neighbour, (In some cases), and many people come unstuck.
Of course, builders know it all, so never forget to mention it to clients !
Even architects are not always as sharp as they should be on the law, but as a chartered surveyor, I am just a little biased.
Not intending to rain on your parade, or your dream, though…!
The frustrating thing is you cannot act for yourself under The Party Wall etc Act, ie on your own property, but in theory you could act for me as my Party Wall Surveyor !
(You would have to keep your fees low as a fellow crafter though…)
