An experienced carpenter can build your loft conversion
A carpenter (see Wikipedia) is one of the oldest professions, we build wooden structures and I am very proud to be one. Carpentry is also a bit of engineering as well as problem solving. There are different levels:
A 1st fix carpenter builds the structure of a house, extension or roof.
A 2nd fix carpenter finishes of a project, hanging doors, fits skirtings, architrave and staircases.
