Whether you live in Twickenham or Central London, if you live in a historic home, you will be restricted to the type of work watchdogs like English Heritage will permit you to carry out, when updating or restoring interiors of your historic home. Even something you deem fairly "harmless", such as bespoke fitted wardrobes for your historic Clapham townhouse, can become a bone of contention with those in charge of national heritage, if the alcove in question happens to harbour authentic late Georgian wallpaper or remnants of early Victorian stencilling.
Before calling in carpenters and specialist joiners, it is important to consult English Heritage's own advice pages online or their authoritative books at the local library. The National Trust also offers Working Holidays that include days spent behind the scenes of some of Britain's great historic homes, providing valuable insight into the do's and don'ts of interior restoration. The Landmark Trust's website is another valuable resource for anyone about to embark on restoring interiors of their historic home that involves bespoke fitted wardrobes, kitchens or other work that is not purely decorative in nature.
Pretty much anything involving drilling into original walls or removing original timber may raise a heritage watchdog's eyebrows. It can prove costly, should one of the watchdogs veto changes already made without prior permission. Finding pictures of approved examples will help specialist joiners and carpenters to come up bespoke fitted wardrobes what will stay within official restoration requirements.
