They did not make me happy at all. I had a person from Federation builders called Maciec Duffka From Dundee to supply and build my shed. At first I thought he did a good job but after examining the shed thourghly i have noticed gaps warping and lots of errors in the shed. Also the door is warped. I emailed the company he bought it from and they said they can't send a new door as this can happen?? They also sent me the receipt for the shed. £498. This person has charged me 950 including delivery. I feel I have been ripped off. Now I need to find someone who can repair this. Not a happy person.
