Multilevel Garden Enhancements: Exploring Six Layered Designs for Vertical Gardening
Sloping gardens can be a challenge, but with careful planning and the right choices, they can be transformed into split-level spaces for relaxation, entertainment, and planting. This guide offers essential tips for designing a safe and effective split-level garden.
Before starting, check with your local planning authority to see if you need planning permission, especially if the changes involve significant earthworks, retaining walls above a certain height, or changes to drainage patterns.
Retaining walls are essential to create level terraces on a slope. Use materials that are both durable and structurally sound, such as reinforced concrete blocks, natural stone, or specially designed landscaping sleepers. Proper design must consider load-bearing capacity, surcharge loads from soil and structures, and most importantly, drainage behind the wall to prevent hydrostatic pressure buildup, which can cause failure.
Proper drainage is one of the most critical elements in split-level garden construction to prevent water pooling and soil erosion. Incorporate slope grading, drainage pipes, or French drains behind retaining walls. Design the garden to direct water away from structures and steps, using natural water flow paths and possibly vegetation that absorbs water well.
Use non-slip, weather-resistant materials for steps, such as natural stone, concrete pavers, or composite decking boards with anti-slip surface treatments. Steps should have uniform riser heights and adequate tread depth.
Tiers can be created from timber sleepers for a rustic effect or stone blocks for durability and a traditional look. Multi-tiered designs add functionality and appeal if well-integrated with the landscape.
Common materials for retaining walls include concrete block walls for strength and longevity, natural stone for aesthetics and sustainability, and timber sleepers for a cost-effective and natural look, though their lifespan is shorter and may require treatment to resist rot.
Incorporate smooth transitions between levels through gradual steps or ramps where possible to improve accessibility and flow. Balancing functionality with aesthetics involves creating distinct zones in the garden, possibly separating dining, relaxation, and planting areas on different levels connected by steps or terracing.
Use natural or environmentally friendly materials to enhance sustainability. Composite decking can be a versatile choice for decking areas on slopes, offering durability and various finishes and colors to define levels distinctly. Adding safety features like handrails on steps and well-lit pathways improves usability.
Engage a landscape architect or specialist garden builder familiar with terraced garden solutions to maximize space usage and ensure structural safety. A sunken patio surrounded by retaining walls can provide a secluded space for relaxation, eating, and enjoying planting.
Grasses and ground cover plants are particularly useful for hiding tiers in an informal garden. Wooden structures, including insect habitats, can be used as an alternative to rendered tiers for a more environmentally-friendly option.
Pressure-treated softwood sleepers should be used for long-lasting tiered gardens, avoiding reused railway sleepers treated with creosote. B&Q, Travis Perkins, and Wickes sell render for walls, but modern rendered tiers can create a minimalist look, but have a significant environmental impact.
In summary, designing a successful split-level garden requires integrating planning permission compliance, structurally sound retaining walls with good drainage, and choosing the right durable, safe materials for steps and tiers, all while creating a functional, accessible, and visually pleasing garden environment. It's advisable to seek help from experts in the planning and building stages of creating a multi-level garden.
