However, building a deck requires close attention to details and good planning along with the right tools and materials. With the right guidance and tools, it is possible for even those without extensive carpentry experience to build this structure.

Raised Deck – Definition, and Importance

The prime function of a deck is to provide a safe, comfortable environment in which you can entertain your family and guests and perform various outdoor activities. Here is the definition and importance of a raised deck. 


A raised deck is an outdoor platform that sits above the ground, supported by a framing system designed to provide stability and strength. It allows for increased flexibility in design and often utilizes multiple levels or tiers.

Ultimately, when constructed properly, a raised deck can effectively enhance any outdoor living space while providing aesthetic appeal as well as safety features.


Raised decks provide a safe and secure platform for entertaining and relaxing, while also offering an aesthetically pleasing addition to any property. The following are some notable benefits of having a raised deck on your property in the UK:

  • An elevated view and better outdoor experience
  • Increases the usable space of the property
  • Better drainage and ventilation
  • An excellent space for entertaining guests
  • Enhance the overall aesthetics of the property

With proper installation and maintenance, you can enjoy your raised deck with peace of mind knowing you have taken steps towards keeping your family safe. You can check our stylish raised decking ideas to inspire your creative mind.

Tools And Materials Needed

Building a raised deck is like building a house but on a smaller scale. It requires the same attention to detail and knowledge of construction techniques. In order to build an attractive and durable structure, you will need specific tools and materials.

Here are three must-haves for DIY costs:

  1. Deck boards: These planks are available in many different sizes and shapes depending on your design needs. You should treat them with waterproofing or rot-resistant material to ensure strength and longevity.
  2. Fasteners: You can use nails, screws, bolts, or clips for attaching the boards together securely so that they don’t separate over time due to weather changes or other environmental factors.
  3. Joist hangers: If you’re using joists as part of your frame structure, then these hangers will help keep them firmly in place while also providing additional support from below.

In addition to these items, you may also need to purchase the following:

  • Concrete footings if the deck isn’t going directly onto soil or grassy terrain
  • Railings for safety purposes
  • Any kind of trim pieces such as corner posts or fascia boards to finish off the look of the project properly.

With these tools and materials ready at hand, you’ll have everything needed to start crafting your one-of-a-kind raised deck. Now, let’s talk about the steps you need to take to build a beautiful raised deck.

Step 1: Building The Foundation

First of all, you need to ensure that the soil on which the structure will be built is sufficiently prepared. It could involve removing any vegetation and checking for soil compaction. It may also require excavation if necessary in order to create an even surface.

You also need to make sure that all ground supports are level and secure. This will prevent problems such as sagging or shifting of wood components over time. You can also consider laying the deck on uneven ground provided you take the right steps.

To build the foundation, use a post-hole digger to excavate holes approximately 12 inches deep and line them with gravel before installing posts. Compact the surrounding soil firmly around the base of each post before moving on to the next step in building your raised deck.

Step 2: Constructing The Deck Frame

Following safety precautions is critical when constructing a raised deck frame with adequate protection from falling hazards. Before beginning construction on the deck frame, make sure to consider:

  • The type of lumber you want to use for support beams and joists in order to build a sturdy structure that can withhold maximum weight capacity safely.
  • Calculate the required number of footings necessary to properly secure the framework into place while preventing movement or shifting once completed.
  • Plan out the layout of the framing elements according to local building codes as well as specific measurements and angles that may be required for your project design.
  • Select appropriate fasteners such as lag screws and carriage bolts that will provide strength and prevent rusting over time due to weather exposure.

As leading experts on decking installations in London, we advise that before proceeding with this essential step, you should ensure all tools and materials are readily available.

Also, you must take proper precautionary measures like wearing eye protection during drilling operations or using gloves when handling heavy objects for your own safety – both physically and legally. 

Step 3: Laying The Decking Boards

Constructing the deck frame is the next crucial step in building a raised deck, and DIYers should take care to get it right. It’s important to ensure that all joists are securely fastened together, with no gaps or misalignments between them, as this will affect the stability of the finished product.

Once the frame is successfully constructed, it’s time to move on to laying down the decking boards. DIY tips for the successful installation of decking boards include starting at one edge of the structure and working your way outwards towards the other side.

This is to make sure you leave enough space between each board for expansion due to changes in temperature and humidity.

To ensure sturdiness, use galvanized nails when affixing the boards into place rather than screws or bolts; these won’t loosen over time like some other fasteners can. Also, make sure to predrill holes before nailing if using hardwood planks since they tend to split more easily than softwoods do.

Step 4: Adding Railings and Stairs (If Required)

When constructing railing systems for decks two meters or higher above grade, there are several special considerations you need to take into account:

  • Choose materials that are resistant to weathering
  • Ensure proper support posts are installed with mounting hardware included
  • Make sure baluster spacing complies with local regulations

When it comes to adding steps, you’ll want them to match the overall style of your deck as well as being safe and secure. To do this, choose treads constructed from durable material like pressure-treated lumber.

You can opt for wide risers to increase foot comfort; include handrails on each side of the stairwell; make sure they have adequate lighting if needed; and ensure they comply with local codes regarding height requirements.

Step 5: Finishing Touches

Once your deck is ready, you can do so many things as finishing touches to enhance the overall appearance of your elevated deck. For example, you have to trim excess decking boards. Likewise, adding fascia boards and skirting can level up your deck.

Not to mention, lighting and accessories are simple ways to turn your raised deck into a beautiful outdoor space. Furthermore, proper decking maintenance will help you maintain the integrity of your deck down the road.
