誰說一定要油返白色油的，改色可以，換門都可以，只要付合大廈防火條例的門都可以

除非得到「房署經理人」的書面批準，否則不得更改單位「大門」的外觀、顏色等，相關擅自的更改將視為「違反裕泰苑公契」。

以下是：裕泰苑 - 公契 - 第73頁 - 第18項
18. Not to paint exterior of building
Except as provided herein and subject to Clause 11(f) of this Deed, not to paint the outsideof the Estate or any part of the said land and not to do or permit or suffer to be done anything which may orwill in any way alter the facade or external appearance (including the paint or colour thereof) of anybuilding in the Estate or main door of any premises in any such building without the prior consent in writing of the Manager.

好奇一問，如果大門唔係花左，而係直頭爛左穿左的話，咁樣點搵返原裝門比佢？

可以問番「房署入伙大使」，佢地會幫到你。
