Building a raised terrace in your garden can transform your outdoor space into a versatile area for relaxation, dining, and entertainment. While many guides focus on standard techniques, we’ll explore an unconventional approach that integrates both aesthetic and practical innovations. We’ll emphasize using concrete bases for the legs and decking for the surface—a method that not only ensures stability but also brings a fresh perspective to garden design.
Part 1: Planning and Designing Your Raised Terrace
1. Understanding the Terrain
- Site Analysis: Before you break ground, thoroughly analyze the location’s slope, drainage, and sunlight exposure. A common mistake is ignoring how water will flow, which can undermine the structure’s stability over time.
- Microclimate Considerations: Consider the microclimate of your chosen spot. How does the wind behave? Does the area stay damp longer after rain? These factors will impact both material choice and maintenance.
2. Material Selection: More than Meets the Eye
- Concrete Bases: While many opt for wooden posts set in the ground, using precast concrete bases for the terrace legs can provide a significant increase in durability. Concrete is more resistant to moisture and pests, which prolongs the lifespan of your terrace.
- Decking Material: Consider using composite decking materials instead of traditional wood. Composites resist warping, splintering, and require far less maintenance. Plus, they’re environmentally friendly, being made from recycled materials.

3. Setting the Concrete Bases
- The Overlooked Importance of Depth: Most guides recommend a shallow depth for concrete footings, but going deeper—up to 2 feet—is a game-changer for stability. This method prevents movement during seasonal ground shifts and ensures the terrace remains level.
- Rebar Reinforcement: Another trick that experts seldom mention is the inclusion of rebar in your concrete bases. Reinforcing bars add tensile strength, preventing cracking and prolonging the structural integrity of the bases.
4. Installing the Decking Frame
- Precision in Leveling: Use a laser level instead of a traditional spirit level to ensure your decking frame is perfectly aligned. Even minor deviations can lead to future problems with decking boards and overall aesthetics.
- Anchoring the Frame: Bolt the wooden frame to the concrete bases using heavy-duty anchors. This method, while slightly more time-consuming, ensures that the terrace will withstand harsh weather conditions and won’t shift over time.

5. Laying the Decking Boards
- The Hidden Value of Spacing: Many DIY guides gloss over this, but spacing between decking boards is critical. Aim for a 3-5 mm gap to allow for expansion and prevent moisture buildup. Too small a gap traps water, leading to faster wood degradation, while too wide can cause tripping hazards.
- Use of Decking Clips: Instead of nails or screws, opt for hidden decking clips. They create a sleek, screw-free surface that enhances the deck’s visual appeal and reduces the risk of splintering.
6. Edge Treatments and Finishes
- Chamfer the Edges: Chamfering (beveling) the edges of each decking board reduces wear and tear on the wood. This small detail adds a refined touch to the terrace’s design while also reducing splintering at the edges.
- Stain and Sealant Selection: Choose a UV-resistant stain and a waterproof sealant specifically designed for outdoor decking. These products protect against fading and water damage, ensuring that your terrace maintains its color and integrity for years.

7. Integrating Green Elements
- Planter Boxes as Railings: Consider using integrated planter boxes as a railing system. This not only provides a unique look but also creates a natural barrier without compromising the view. Use low-maintenance plants like succulents or ornamental grasses that can thrive in the sun.
- Deck-Level Water Features: Most terraces focus solely on plant elements, but adding a small water feature at deck level can create a serene ambiance. A simple, self-circulating water fountain can also help mask neighborhood noises, turning your terrace into a peaceful retreat.
8. Solar Integration
- Solar Deck Lights: Install solar-powered lights directly into the decking. Not only do they illuminate the terrace at night, enhancing safety and ambiance, but they also eliminate the need for complex wiring.
- Photovoltaic Decking Panels: For the environmentally conscious, consider photovoltaic decking panels that generate electricity. Though still relatively niche, they can power outdoor lighting or charge batteries for garden tools.
Part 5: Long-Term Maintenance and Considerations
9. Maintenance-Free Innovations
- Self-Cleaning Decking: Look into self-cleaning decking treatments that are available in the market. These coatings help shed dirt and debris when it rains, reducing the need for frequent scrubbing or pressure washing.
- Anti-Slip Solutions: Mix a fine grit into the final layer of sealant to create a slip-resistant surface. This is particularly important if your terrace will be exposed to rain or if you live in a humid climate.
10. Seasonal Care Tips
- Winter Preparations: Before winter sets in, ensure the decking is free of leaves and debris. Any organic material left on the decking can lead to staining and mold growth.
- Annual Inspections: Make it a habit to inspect the concrete bases annually for cracks or signs of settling. Early detection of issues will allow you to address them before they become major problems.
Conclusion: Rethinking Raised Terrace Design
Building a raised terrace in your garden using concrete bases and decking is not just about creating an outdoor space—it’s about redefining what that space can be. By integrating unconventional methods, like deeper concrete footings and rebar reinforcement, and focusing on innovative ideas like solar integration and chamfered edges, you’ll create a structure that is not only durable but also uniquely yours.
This approach challenges the conventional wisdom of garden terrace construction. Instead of settling for temporary solutions that require frequent upkeep, you’re investing in a long-lasting, sustainable space that can be enjoyed year-round with minimal maintenance.
