If you’re planning to extend your property it’s good to have an indication of the likely cost of the project. Well, GrowYourHome.com offers just that and it’s completely free. Simply enter a few details about your plans and create a user account and you can obtain an estimate for your project in a matter of minutes.
Of course this is no substitute for getting a quote from a builder who has seen your property but it will give you a good idea about the likely cost of the work and should help you when you have discussions with any builder.
