We design conservatories for several leading specialist companies throughout Kent. Generally, Conservatories are exempt from Building Regulations (up to a size of 30M2) but often require planning permission due to their projection and proximity to neighboring properties.? In order to qualify as exempt under building regulations the existing external doors and windows should remain in-situ. Usually if a conservatory only extends 3000mm or less from the main rear wall of a property then full planning approval will not be required. In this situation Anderson North Ltd would recommend applying for a lawful development certificate to avoid issues arising at the time of selling the property.
An orangery is similar to a conservatory but usually has a solid roof structure. The external doors and windows of the existing property should remain in place, otherwise the constraints of an extension will apply, particularly concerning glazing limits. The walls and roof of an orangery only need to meet the same heat loss levels of a conservatory. Orangeries are very popular for garden rooms where the temperature within a conservatory would be uncomfortable. Anderson North Ltd are happy to design one off bespoke orangeries and have carried out dozens of similar projects throughout Kent.
