What is Raised Decking?

Definition and Key Features

Raised decking is an elevated platform supported by posts or pillars, typically built higher than 30 cm (12 inches) above ground. It is often attached to a house, creating a natural extension of indoor living space, but it can also be freestanding.

Raised decks are ideal for properties with uneven terrain, making use of sloped areas that might otherwise go unused. They also take advantage of vertical space, providing additional outdoor living areas with opportunities for storage, seating, and multi-level designs.

Pros of Raised Decking

Raised decking offers several benefits, making it a great choice for homes with uneven terrain or those looking to maximise outdoor space. Here are some key advantages:

• Better views: Provides scenic outlooks, perfect for homes in elevated locations.
• Optimises uneven terrain: Makes sloped or difficult landscapes more usable.
• Creates extra outdoor living space: Ideal for extending second-floor areas.
• Reduces moisture-related issues: Less exposure to damp conditions, helping to prevent rot.
• Customisable design options: Can include railings, stairs, under-deck storage, and multi-level layouts.

Cons of Raised Decking

While elevated decks have many benefits, there are some drawbacks to consider before making a decision. Here are the main disadvantages:

• Higher construction costs: Requires more materials and labour.
• Additional safety measures needed: Railings are mandatory for decks over 60 cm (24 inches) high.
• Permit requirements: May need planning permission due to height and complexity.
• More complex installation: Needs a strong support structure with deep foundations, which may require a professional deck builder.

Building Regulations for Raised Decking

In the UK, planning permission is required for raised decking if it stands more than 30 cm (12 inches) above the ground. Regulations also apply if the decking, along with other extensions, covers more than 50% of the garden.

Checking local building codes before starting construction is essential to avoid potential legal issues.

Best Uses for Raised Decking

Raised decking is ideal for homes on sloped or uneven terrain, as it helps maximise space and improve usability. It works well for creating multi-level outdoor areas, adding both function and visual appeal.

Properties with scenic views benefit from an elevated garden deck by providing a better outlook over gardens and landscapes. Homeowners looking to extend their living space can also use raised decking to create a seamless transition between indoor and outdoor areas.

What is Ground-Level Decking?

Definition and Key Features

Ground-level decking is a low-profile structure built at or near ground level, typically under 30 inches high. It is often freestanding but can be attached to a home for added convenience. With a simpler design, it is easier to install and maintain compared to raised decking.

This makes it a popular choice for homeowners looking for a cost-effective and practical outdoor space. Its seamless integration with the landscape allows for a natural and open feel, making it an attractive addition to gardens and patios.

Pros of Ground-Level Decking

Ground-level decking is a practical and cost-effective choice for many homeowners. It provides a seamless connection to outdoor spaces while being easier and more affordable to build. Here are its key benefits:

• More budget-friendly: Requires fewer materials and lower labour costs.
• Seamless landscape integration: Blends naturally with the surrounding garden.
• No railings required: Maintains an open and unobstructed look.
• Fewer permit requirements: Typically involves less regulatory hassle.
• Easier installation: Ideal for DIY projects without professional assistance.

Cons of Ground-Level Decking

While ground-level decking is a convenient option, there are some drawbacks to consider. Its lower elevation can affect views, durability, and privacy. Here are the main disadvantages:

• Limited views: No elevation for scenic outlooks.
• Less effective on uneven terrain: May require landscaping adjustments before installation.
• Higher maintenance needs: More susceptible to drainage issues, pests, mold, and moisture damage.
• Reduced privacy: Lower elevation makes it more exposed to neighbours and surrounding areas.

Building Regulations for Ground-Level Decking (UK)

In the UK, planning permission is generally not required for ground-level decking. However, approval may be needed if the deck, along with other extensions, covers more than 50% of the garden.

Homeowners should always check local regulations before starting construction to ensure compliance with building codes.

Best Uses for Ground-Level Decking

Ground-level decking is perfect for level gardens and patios, creating a smooth and functional outdoor area. It is a great choice for budget-conscious homeowners, as it is cost-effective and easy to maintain.

With its easy access and open layout, it works well for outdoor entertaining spaces, such as seating areas and dining zones. The simple decking installation process also makes it ideal for DIY projects, allowing homeowners to customise their decks without professional assistance.

Comparing Raised Decking and Ground-Level Decking

Key Differences

The main difference between raised and ground-level decking is height. Raised decks sit above 30 cm (12 inches), while ground-level decks remain close to the ground.

Raised decks require a sturdy structure with posts, beams, and diagonal bracing, whereas ground-level decks can rest on a gravel base or concrete piers. Raised decks also need deeper foundations for support.

Permit requirements vary, with raised decks often requiring planning permission, while ground-level decks typically do not. These structural and legal differences play a big role in determining which option is best for your outdoor space (1).

Cost Considerations

Raised decking is more expensive due to the additional materials, labour, and permits required for its construction. The need for posts, railings, and stairs further increases costs. In contrast, ground-level decking is more affordable, as it requires fewer materials and less labour.

Its simpler design also makes it easier and cheaper to install, especially for homeowners looking to take on a DIY project. If budget is a primary concern, a ground-level deck is a more cost-effective option.

Durability and Maintenance

Raised decking is less prone to moisture damage since it is elevated off the ground, reducing the risk of rot, mould, and pest infestations. However, its structure is exposed to weathering and general wear over time, especially on the support beams and railings.

Ground-level decking, on the other hand, is more vulnerable to moisture issues as it sits directly on the ground. Poor drainage can lead to rotting wood, pest problems, and structural damage, requiring more frequent maintenance.

Safety and Accessibility

Raised decks require railings and stairs for safety, making them less accessible for children, elderly individuals, and those with mobility challenges. Stairs can also pose a slip hazard in wet weather.

Ground-level decks offer easy access, as they provide a smooth transition from indoor spaces to the garden without the need for steps or railings. This makes them a safer and more practical option for families and individuals with mobility concerns.

Aesthetic Appeal and Design Flexibility

Raised decking offers elevated views and works well for multi-level outdoor spaces. It allows for under-deck storage and can be designed with railings, stairs, and multiple levels to create a dynamic outdoor area.

Ground-level decking provides a seamless, natural look, blending effortlessly into landscaped gardens. Its low-profile design makes it feel more integrated with the surrounding environment, making it an excellent choice for homeowners who prefer a minimalist or open-concept outdoor space.

Frequently Asked Questions

What Is Best for Composite Decking, Raised or Ground-Level?

Both raised and ground-level decks can use composite decking materials, but the best choice depends on your needs. Raised decks suit uneven terrain and offer better views, while ground-level decks provide easier installation and a seamless garden connection.

Composite decking resists moisture, rot, and pests, making it durable for both. Consider your budget, garden layout, and usage when deciding.

What Is a Multi-Level Deck?

A multi-level deck has two or more connected platforms at different heights. It works well for sloped gardens or large spaces, creating distinct areas for dining or lounging. Multi-level decks add style and function, often featuring stairs, railings, and seating. They help maximise outdoor space and usability.

Conclusion

Choosing between raised and ground-level decking depends on your budget, landscape, and how you plan to use your outdoor space. Raised decks are ideal for uneven terrain, better views, and extra living space, while ground-level decks offer a budget-friendly, low-maintenance option with easy access.

Both can be built with composite decking materials for durability and style. Understanding costs, maintenance, and permit requirements will help you make the best decision.

Whatever you choose, a well-designed deck enhances your home’s outdoor space and provides a functional, enjoyable area for years.
