Will removing a chimney breast devalue my home?

Chimney breasts are character features of older homes, giving the house a UK traditional feel. When it comes to selling your home, buyers who are attracted to your home over a newbuild contemporary home will seek out your home for its offers like a chimney breast. The complete removal of the chimney breast may leave them buying elsewhere, however the conversion of a chimney breast, e.g.; for a space to house their log burner or cooker will still give the house the traditional feel they crave with a modern use for the chimney breast and perhaps add more value to the house than the complete removal.

Of course, like so much, this is purely based on personal opinions, because another buyer might appreciate the additional space that the removal of the chimney breast has added in a room such as a bedroom. Be sure to keep records of Party Wall Agreements and any structural improvements as new buyers will want to see this documentation. Like with any project, before going ahead, do your research and see what similar homes in your neighbourhood have sold for, with and without chimney breasts to help you come to the best decision. Also, if this is your forever home, then a devalue would not matter as much.
