What is the value added by building an extension?

Converting a garage into a bedroom with an en-suite could add as much as 20% to the value of your home.

If you use it to create an additional living , play or work space you could realise a 10% increase in value.

You don’t have to extend !

Instead of  building the extension, you could get the planning permission granted.

This will make your home more attractive to potential buyers who want to extend , the peace of mind for the buyer knowing that permissions are in place will add value without you having to go to the tie and expense of carrying out the build yourself.

In summary, to some degree “ Value” is in the eye of the beholder, like myself you may not mind the cost if you get a decade or more of pleasure and usage of the space or if your looking to move with a profit than you need to get the calculator out!

Whatever your motivation, you can not expect a reputable builder to provide an accurate quotation without seeing a set of drawings first, you do not need to have applied for planning permission (you can save that cost until after the quotes have come in) for them to quote.
