A garden office is an office in a garden. This is usually separate to a house, being used as a dedicated office space by a professional homeworker or by a home-based business.
In the UK, planning permission is not normally needed for a garden office if it is similar in size and construction to a garden shed. The cost will depend upon the facilities and will be between £5,000 and £60,000. Internet and phone connections may be required and this can perhaps be achieved by use of a wireless network based in the main building.[1]
