Orangeries were traditionally a luxurious extra built on grand homes between the 17th and 19th centuries used to grow oranges and other fruit trees. Now, Orangeries are a popular way of extending a home, combining the perks of a conservatory, whilst offering the safety and security that you get from an extension. Choose from timber, aluminium, or a combination of materials to suit your space.

When people think of extensions, they often think of conservatories. Cornwall is a beautiful county to enjoy all four seasons from a lovely glass conservatory that lets the light in and keeps the rain out. Adding another room creates space and boosts value. Our firm builds Cornwall conservatories using either traditional or modern building methods.

Save Money With Energy Efficient Windows

Installing energy-efficient windows in homes could reduce energy bills by over £150 per year.

Energy-efficient double or triple glazing keeps the heat inside your home. The thermal insulation keeps spaces warm in the winter. Extra ventilation options can bring cool breezes to you during the sunny months.

Make Every Entrance Grand

Many people see a door as just a way of getting in and out of a property. We believe front doors can be so much more. A beautiful door can really change the look of your home by adding kerb appeal and value. Modern doors also bring extra security.
