How to Install Decking


Reading time: 6 mins


Why build elevated decking?

Building a raised deck is a great way to make the most of space that otherwise would go unused, such as slopes and uneven areas. In general, installing decking has a lot of advantages; it can transform your garden area, adds value to your property, is low maintenance and is relatively cheap to install. Elevated garden decking is an excellent way to create an outdoor living space that can be used for both relaxing and entertaining. 


Do I need planning permission for raised decking?

Whilst local planning laws can be complex and vary from place to place, for the most part, you do not need to apply for planning permission for your decking provided that:

  • The decking is no more than 30cm above the ground.

  • Together the total area of all the extensions, decking and platforms don’t cover more than 50% of the garden area.

  • None of the decking or platform is on land near the front wall of the house.


How to prepare the ground for raised decking

There are a few things to check for when preparing the ground for raised decking:

  • Shade and privacy – if you decide to use a permanently shady spot, be prepared to clean the wood once a year to preserve the timber from dampness.

  • Excessive wetness – avoid very wet areas completely as this will eventually cause the wood to rot.

  • Immobile fixtures in the garden - features such as trees and posts that you will have to navigate around.

Before you begin to install your deck, you will need to fit decking posts. You can do so in three easy steps. Be sure to also check the manufacturer’s guidance for product-specific instructions:

  • Step One: Measure and Mark Out the Area
  • Step Two: Prepare Post Holes
  • Step Three: Install the Posts
