I can recommend a fantastic carpenter who we have used a couple of times for wardrobes/cupboards and a built-in bookcase - his name is Billy King (07814 492 755 or
kingandparcel@gmail.com) & I found him through Annabel on this site, and his work is of a really high standard. He is also very easy company to have round the house - the kids love him, he's friendly/chatty, but doesn't feel the need to tell you his life story; very tidy/ cleans up after himself; reliable (i.e. turns up when he says he will) etc. Probably not the cheapest, but you get what you pay for, so I would say he is excellent value. Highly recommended.
