In House Manufacturing

Pay a visit to our factory and get inspiration for the design of your own  home. By enjoying  a  leisurely  chat  with our  well-informed, friendly   staff  you  can  sit   back,  relax  and  get   a  feel   for  our craftsmanship – all  you have to do is decide  what yours will look like from the designs and styles we can offer you.

Our Conservatories

If  you decide  to  enhance  your  home  with  our  conservatories, we will arrange  a  visit to  your home and guide you through this most important stage, including  discussing  the style  you require  as  well as any special requirements. Production of a computer-aided design drawing is the next step–this  can be altered or revised to ensure the proposed conservatory will meet all your needs and expectations perfectly.


We ensure that our warranty and service department will  aim to provide excellent standards of care and dedication to you throughout your whole experience. Even  after your installation, we will still have your interests  at heart; and continue to keep in touch; we wouldn’t have it any other way. If you  choose us to install,  on all   our installations we offer a  10 year insured back  guarantee with the Plastic Window Federation.
