A sloping backyard doesn’t rule out a pool. In fact, building a pool on a sloped site often creates the opportunity for some of the most striking designs, from vanishing edges to split-level pool and spa combinations. It does, however, require careful planning, engineering and an experienced concrete pool builder.

When researching this topic, you may also see it described as:

• Pools for sloping blocks
• Sloping block pool builders
• Pools on a hillside
• Pools on uneven ground
• Semi in-ground pools
• Split-level pool designs

On a flat block, a pool is excavated into level ground. On a slope, the pool has to be designed so that part of the structure is cut into the hill and part may be built up above natural ground level. This affects the engineering, drainage, access and even your safety barrier.

The key steps usually include:

• Site survey: measuring levels across the site to understand the fall of the land.
• Soil (geotechnical) assessment: Melbourne soils vary widely, from reactive clays to rock and sand, which affects footings and excavation.
• Structural engineering: designing the pool shell, footings and any piers to resist the load of water and soil.
• Retaining walls: where soil is cut or filled, retaining walls may be needed. Walls over a certain height, or near boundaries and buildings, generally require engineering and a building permit.
• Drainage: diverting stormwater and subsurface water away from the pool and surrounding structures.
• Access: planning how machinery and materials will reach the site.

Every pool in Victoria also needs a building permit and a compliant safety barrier. Read about Victorian swimming pool and spa regulations.

A slope gives you design options that a flat block can’t offer. Popular approaches include:

• Cut-in pools: the pool is set into the slope, with the high side retained and the pool sitting level with your outdoor area.
• Semi in-ground pools: part of the pool sits above ground, with the exposed walls finished in stone, tile or render to become a design feature.
• Infinity and vanishing edge pools: the low side of the slope is used to create a vanishing edge that takes advantage of the view. Explore our infinity swimming pools and our guide to infinity and vanishing edge pools in Victoria.
• Split-level pool and spa: a raised spa spilling into the pool below makes use of the natural fall. See our pool and spa projects.
• Tiered outdoor areas: terraces, decks and retaining walls create separate zones for swimming, lounging and entertaining.
• Water features: waterfalls and sheer descents can use the change in level. Discover our pool water features.

Building a pool on a sloped site usually costs more than a pool on a flat block, but careful design can make the most of your budget. Factors to consider include:

• Degree of slope: the steeper the site, the more excavation, retaining and engineering is usually required.
• Soil and rock: rock excavation or reactive soils can add to the cost and time involved.
• Retaining walls: these can be a significant part of the budget, but can also double as features or seating.
• Site access: narrow or steep access can limit machinery and increase labour.
• Pool position: placing the pool to balance cut and fill can reduce soil removal and retaining.
• Safety barriers: changes in level, retaining walls and nearby structures need to be considered when planning compliant pool fencing.
• Equipment placement: pumps, filters and heating need to be positioned to suit the different levels of the site.

Exotic Pools offers a full range of custom concrete pool design and construction services across Melbourne and Victoria:

• Family Pools – Designed for fun and entertaining, with options such as wading areas, integrated spas and water features.
• Infinity Pools – Vanishing-edge designs for properties with a view.
• Lap Pools – A dedicated swimming lane for fitness, ideal for long, narrow spaces.

A sloping site can be the starting point for a truly spectacular pool. With the right site assessment, engineering, drainage and design, a slope can become a feature rather than an obstacle, whether that’s a vanishing edge, a split-level pool and spa or a tiered outdoor entertaining area. Because every slope is different, a custom concrete pool designed specifically for your site is usually the best solution.

Since 1990, Exotic Pools has designed and built custom concrete pools across Melbourne, including many on sloping and challenging blocks. With more than 30 years of experience, we know how to turn a difficult site into a stunning outdoor space.
