On behalf of my friend.
Friend is self employed as a gardner/landscaper and has been branching out into making wooden furniture when he has quiet periods (which he has not much of atm). He needs more space to store his large tools, and also to be able to make his furniture.
Can he reclaim the tax back on building a large workshop to accomodate the expansion of his business in his garden? (obviously subject to the normal planning permissions required), as he is registered self employed?
