party wall agreement 你就咁拍門叫隔黎簽個名就得. 份agreement 點寫, internet google 就搵到.
Lawful development certificate 我會叫你搵architect 跟番. 因為你一錯, 或者漏左野, 就無左2個月時間. 仲有嘅係, 問清楚architect 係咪真係Lawful development certificate 就夠做. 我個陣係先申請Lawful development certificate, 跟住ban 鳩左我話我要做嘅extension 一定要入planning permission 先得. 變左我入左2次紙, 一次Lawful development certificate, 一次planning permission. 俾左2次錢, total 等左4個月.
