Whether your proposed conservatory design needs planning permissions is one of the most important considerations while designing your conservatory project. There are a few limits set by the authorities that exempt certain structures from the need to apply for planning permissions. The need for planning permissions hence depends on the project specification and location. Conservatory addition generally falls under ‘permitted development’ rules. However, this is subject to certain specific conditions which as of 25th
May 2019, saw a few amendments. These basically relaxed some conservatory development rights to allow larger extensions without the need for planning permissions.
When are planning permissions generally not required?
· Terraced and semi-detached homes are permitted to make additions up to 6 metres
· Detached houses can add large structures up to 8 metres
In the case of a conservatory or single-storey extension planning permission is usually not mandatory if:
· Maximum height of 4m high within 2m of a boundary
· The conservatory does not cover more than 50% of the garden.
· Roof ridge or highest point is not higher than the eaves of a property’s roof
· Side extensions do not extend beyond 50% of the width of the house
There is a ‘Neighbour Consultation Scheme’ involved which protects the interests of the neighbors if they stand to be affected by the new structure and can raise objections to such extensions.
