So....bit of a piece of string question this but.... Out house was valued at £180000 in 2006. Since then we have knocked down the scary, asbestos garage and had an extension done adding a porch, additional front room and double bedroom downstairs. Is lush so an v happy. Having it valued on Monday but do any of you know how the prices would have changed since 2005 without the extension? And/or have any idea what value the extension would add?
