I appointed C1 Builders to convert a light industrial unit to two residential dwellings. The building needed to be totally stripped out ,including a new roof, C1 Builders did a superb job, they kept me completely updated with the progress which included regular on site meetings . I would have no hesitation in using them again, and i would highly recommend them. A truly professional company. - B S
