When building a deck, bear in mind that you may need planning permission. There are certain considerations, such as the proposed height and size of your decking, that might make this necessary. Always make sure you have checked with your local authority that planning permission is or isn’t needed. Don’t be tempted to build it and hope for the best as you may be forced to take it down.
Additionally, you need to ensure that your planned decking complies with all relevant building regulations – this is different to planning permission.
As well as contacting the Local Authority, have a chat with all neighbours that might be affected by the project. If you are building the deck in an area that is overlooked by neighbours, it’s a polite courtesy to let them know, whilst you may not need their permission, it never hurts to keep them informed. Neighbours that share a boundary with you and those whose gardens you might overlook and those affected by the potential noise, dirt and commotion of the decking being built should all be informed of your project. Neighbour objections are the most common reason for planning refusal or restrictions imposed by the authorities, so early discussions can help you with this.
