Welcome to our site
We are builders in Harrogate & Yorkshire
Take advantage of Knox Developments experience and allow them to help you create your dream space using their imaginative and innovative ideas. Each loft can be fully customised to create the room that you need. We can convert your attic into the bedroom, study, gym or playroom you have always dreamed of.
We offer a design to completion service but would be more than happy to liase with your chosen architect.
Not enough head height? Then a loft extension maybe the answer. By building a new roof at a steeper pitch you could add an extra floor to your home.
Why not take advantage of our free, no obligation design service
