Conservatory Styles To Suit Every Home
Frequently Asked Conservatory Questions
The majority of conservatories do not need planning permission. That is because they fall under the bracket of permitted development. There are a variety of factors that affect planning permission. However, we can help if you need planning. We have a team of experts on hand to help make the process as stress-free as possible.
A conservatory needs to have a solid foundation, similar to a house. That is because it is an extension of the living space in your property. Without foundations, your conservatory would be prone to moving and falling. That is why a foundation is crucial and comes as part of our building process.
If you want to know more about how we lay our foundations, get in contact with our team. Call 01744 611 203 to find out more.
Although uPVC conservatories are a popular choice, we can also offer Aluminium conservatories. Our uPVC designs will have a similar look to the majority of the extensions you will see. However, we can make each design unique to your preferences.
On the other hand, our Aluminium conservatories have a slimmer framework. These conservatories are a stylish choice and are easy to maintain.
A correctly built conservatory can last for years with the right care and maintenance. When we design your extension, our team will be able to take you through the things you need to know to ensure your conservatory stands the test of time.
Conservatories tend to feature less brickwork and come with a large area of windows. Orangeries, on the other hand, look similar to an extension. We tend to build our orangeries with brick, and they are perfect with a lantern roof. That boosts the natural light in your home.
