A Buyers Guide to Consevatory Design
A well designed and correctly specified conservatory can provide a superb room, Providing valuable extra space, and making a great financial investment. But only of you get the design and specification right. It is difficult for us to distill decades of experience and un-rivalled product knowledge in to a single web page, but here are a few things to consider when planning your conservatory.
1. Conservatory guide to statutory requirements
This covers the potential need to obtain
• Planning Permission
• Building Regulations
• Permission under the Party Wall Act
• Permission Under any property covenants
There is insufficient room to go into the full details of the above on this page, some of which is covered elsewhere on many of our other pages, however, since every home in the country is individual and the interpretation of regulations varies from one Local Authority to another then it is important to obtain written confirmation prior to starting work whether or not the conservatory will be defined as Permitted Development and consequently will not require a Full Planning Permission application, or an application for Prior Approval, it should be noted that a conservatory can now have an unlimited amount of brickwork to the side elevations, after the ammendments to the Building Regulations in September 2010
2. Conservatory guide to site considerationsThe factors here to consider, that will affect your conservatory design are
Height restrictions on the existing house - that may mean a boxgutter conservatory or low pitch conservatory is required. You can view lots of examples of projects incorporating boxgutter on our boxgutter conservatories page
Obstructions on the house wall, such as pipes and boiler flue outlets need to be dealt with. Soil pipes and such are easily boxed in, but of course a boiler flue cannot expel into the conservatory. Many flues can be ducted, but at worst the boiler itself may need to be resited. Boiler flues are a real safety issue and work needs to be undertaken by an approved Gas Safe engineer. The minimum distance from a boiler flue to the conservatory is typically 300mm, but this can vary and should be confirmed in each individual case.
Outside ground level, will extra build up be required, or if the outside ground slopes towards the house a retaining wall may be required.
Underground and drainage issues. Of course building over pipes can be straighforward but inspection chambers are more complex. More often than not inspection chambers can be raised and sealed inside the conservatory and only really present a problem if they are in the line of the foundations.
Soil conditions especially clay in the soil. If this extends to any serious depth then this will need to be addressed in the foundations stage, possibly with the installation of Clayshield foundation protection. Proximity of trees can also affect the foundation solution required.
