Available with a Glass or Solid Roof

At a basic level, a glass roof will allow more light to come into your conservatory whilst a solid roof will make it look and feel more like a traditional extension does. However, there are various other differences between them and you can learn more about these by clicking on the links below.

Glass Roofs

As I'm sure you are well aware, glass roofs offer maximum light intake. However, thanks to modern innovation, they now excel at trapping warmth inside too.

Are modern conservatories energy efficient and secure?

Whatever you decide, our naturally insulating uPVC frames and high-quality glazing ensure that your new modern conservatory will have no problem staying warm. We also provide the option of low-e glass, which works to reflect heat away from the conservatory, so they are able to stay cool during soaring temperatures.

Any doors and windows on your uPVC conservatory will be equipped with a range of leading security hardware, so your new space won’t be a security risk either. With security and comfort guaranteed, you can confidently use your new conservatory in whatever you please, whether that’s as a kitchen, dining room or something else entirely.

What is the difference between an orangery and a conservatory?

The main difference between an orangery and a conservatory is the amount of glazing used within the structure. Traditionally conservatories are made up of a glass roof, a glazed structure, and a brick dwarf wall. On the other hand, orangeries traditionally have a flat roof with a central glass lantern, a brick structure, and large, glazed windows. However, the difference between the two glazed extensions has blurred over the last few years due to the flexibility homeowners have when it comes to designing them. With tiled conservatory roofs, fully glazed structures, and roof lanterns surging in popularity, homeowners are mix and matching features from both styles of glazed extensions, to create something completely unique to them.

What are the rules for a conservatory?

The rules for a conservatory can vary depending on your location and the specific regulations in your area. However, there are some general guidelines that apply to most conservatories:

1. Size: The size of the conservatory cannot exceed 50% of the total land area around the original house. The maximum size of a single-story conservatory without planning permission is 4 meters in height, and 3 meters in depth for a semi-detached or terraced house, and 4 meters in depth for a detached house.

2. Placement: The conservatory must be built at ground level and cannot be placed forward of the principal elevation of the property. The conservatory cannot be located in a front yard that faces a road without planning permission.

3. Materials: The conservatory must be constructed with materials that match the existing property and not have a balcony, veranda, or raised platform.

4. Glazing: All glazing and fixed electrical installations in the conservatory must comply with building regulations.

5. Heating: The conservatory must have independent heating controls with a separate on/off switch.

6. Planning Permission: If your conservatory does not meet the requirements for permitted development, you may need to apply for planning permission from your local authority.
