How To Build A Raised Deck In Your Garden: A Step-by-step Guide

A raised deck is an attractive addition to any garden and is a great way to make the most of your outdoor living space. However, it can be an intimidating prospect when it comes to building your own. Thankfully, a raised deck isn’t as difficult as you think. This step-by-step guide will help you build a raised deck from the ground-up.

Step 1: Gather Materials and Tools

The first step for building a raised deck is to gather the necessary tools and materials. You will need:

  • Deck screws or nails
  • Exterior grade composite deck boards
  • Galvanized joist hangers
  • Pressure treated deck joists
  • Deck posts
  • Concrete mix
  • Drill
  • Circular saw
  • Shovel
  • Level
  • Hammer

Step 2: Determine the Size and Layout of Your Deck

Once you have your materials and tools, it’s time to decide on the size and layout of your raised deck. Make sure to keep the size manageable, so that it won’t be too difficult to build and maintain. You will also need to decide on the height, and whether you want any railings or stairs.

Step 3: Clear and Level the Area

Once you have decided on the size and layout of your deck, it’s time to clear the area and make sure it’s level. This can be done by removing any vegetation and loose debris, and by using a shovel or level to even out the ground. Make sure to dig out any area that needs to be lower, and add soil or gravel to any area that needs to be higher.

Step 4: Lay the Deck Posts

Next, you will need to lay your deck posts. Deck posts should be placed at 8-foot intervals, and should be pressure treated for increased durability. You will also need to make sure the posts are level and plumb. Once the posts are in place, you can then attach the joist hangers.

Step 5: Attach the Joists and Deck Boards

Now it’s time to attach the joists and deck boards. Start by attaching the joists to the deck posts in between the joist hangers, using deck screws and a drill. Make sure the joists are level and secure, then move on to attaching the deck boards. Start at one end of the deck and attach the boards with deck screws, and make sure the boards are flush with each other.

Step 6: Secure the Deck to the Ground

The last step is to secure the deck to the ground. This can be done by using concrete mix to fill in any gaps between the ground and the deck. Make sure the concrete is level and flush with the ground, and allow it to dry before adding any furniture or railing.


Building a raised deck in your garden is a great way to increase your outdoor living space. With the right tools and materials, and by following this step-by-step guide, you can build a raised deck from the ground-up in no time. With a little effort, you can build a beautiful outdoor living area for you and your family to enjoy for years to come.
