# Garden offices and extensions

Buildings are not tax deductible, and therefore garden offices or extensions for the purposes of working from home cannot be claimed as a business expense.

Although buildings are exempt, you can claim for fixtures and fittings, such as desks, chairs, storage etc which are used exclusively for the business.
