Specialists in
Barn Conversions


Dafydd @ D.O.Roberts Builders is a very skilled builder and project manager. He did a conversion for me on two derelict farm buildings to a very high standard, so much so we nominated him for builder of the year to the Federation of Master Builders and they came runner up in the medium renovation project category. Look at www.cottagetorent.org to see the quality of his work, it is outstanding.
