We are a family run business who have been trading in Mid Cornwall and Devon for over 30 years. All upvc products are manufactured in our factory as well as all glass sealed units. We are one of the few remaining manufacturers left in Cornwall, but we feel passionate about this side of our business. We find it gives us more control over supplying you, our customer with great products and more flexible lead times.
Conservatory designs
On the following pages we will show you some of the choices available to you in terms of window and door options, coloured profile, glazing options and hardware choices. Other areas covered are traditional and contemporary designs of conservatories, orangeries and lantern roofs. All offered in upvc, aluminium and wood.

Professional advice always available

We are here to help with friendly advice on all your home improvement needs. From design, to planning through to completion we are here to help in every way.

Please browse through our site and we hope you find it informative. If you have any questions, please give us a call or email. We are only too happy to talk about your future project

We have tried to include all our products on this website. However, at the end of the day there is no better way of making a decision than seeing the products first hand. Our showroom is a showcase of all we have to offer. We are open Monday to Friday 7am to 5pm and we have plenty of free onsite parking. Come and relax in one of our full size conservatories with a cup of coffee while you make your final choices on your new dream extension. We also have  pvc and composite door displays as well as a selection of windows to help with your final decisions.
