A well-designed patio should do more than fill an empty part of the backyard. It should create a comfortable place to eat, entertain and relax while fitting naturally with the home, gardens and surrounding landscape.
Interlocking stone is a popular choice for Ontario patios because it offers flexibility in colour, texture, pattern and layout. It can be used for everything from a compact seating area to a complete outdoor living space with steps, retaining walls, an outdoor kitchen or a pool.
The finished appearance matters, but the decisions made before construction—size, grading, drainage, elevations and base preparation—have the greatest effect on how well the patio performs.
Start With How You Want to Use the Patio
Before selecting pavers or colours, decide what needs to happen on the patio.
Consider whether the space will include:
- A dining table and chairs
- A barbecue or outdoor kitchen
- A conversation or lounge area
- A fire table
- A hot tub
- A pergola or pavilion
- Access to a pool
- Steps or walkways connecting different areas
Think about how many people will regularly use the patio and where they will move through the space. Chairs need room to pull out, barbecue doors need clearance, and walkways should not force people through the middle of a seating area.
Planning around the furniture and activities first helps prevent a patio that looks attractive but feels cramped or awkward.
Choose the Right Patio Size
One of the most common patio-planning mistakes is making the space too small.
A patio may appear generous when empty, but furniture, planters, cooking equipment and traffic routes quickly use the available room. Marking the proposed area on the ground can make the dimensions easier to understand before construction begins.
When planning the size, allow space for:
- Chairs to move away from a table
- Comfortable walking routes
- Safe clearance around a barbecue or fire feature
- Doors, gates and stairs to open properly
- Future additions such as shade structures or an outdoor kitchen
- Planting beds to soften the edges
The patio does not need to occupy the entire backyard. A well-proportioned space with room for gardens, lawn or other landscape features often feels more inviting than one large uninterrupted surface.
Let the Home Guide the Layout
The patio should feel connected to the house rather than added as a separate platform.
Door locations, windows, existing steps and the architecture of the home all influence the best layout. The patio should provide a natural transition from indoors to outdoors without creating awkward elevation changes.
Straight lines and large-format pavers often suit modern homes, while more traditional paver shapes and gently curved edges may complement an older or more detailed exterior.
The shape should also respond to the property. A rectangular patio may make the most efficient use of space, while curves can help work around gardens, trees or other landscape features.
Select Interlock That Fits the Project
Interlocking pavers are available in many sizes, finishes, colours and price ranges. The right material should suit the home, the intended use and the scale of the patio.
Consider:
- The exterior colours of the house
- Existing stone, brick or concrete
- The size of the patio
- The desired style—modern, traditional or natural
- Texture and slip resistance
- Availability of matching steps, walls or borders
- How the colour will look in sun and shade
Large-format pavers can create a clean, contemporary appearance, but the site and installation method must be suitable for the selected product. Smaller pavers offer flexibility for curves, patterns and detailed areas.
Avoid choosing from a small sample alone. Whenever possible, view several pieces together and look at completed installations in natural light.
Use Colour and Pattern Carefully
A patio does not need several competing colours and patterns to feel custom.
In many projects, the strongest result comes from one primary paver complemented by a restrained border or accent. The border can define the patio edge, connect it visually to a walkway or highlight a change between different areas.
Popular approaches include:
- One paver throughout for a simple, cohesive appearance
- A contrasting border around the perimeter
- A subtle colour blend that complements the home
- Different paver sizes used within the same product collection
- A change in direction or pattern to identify a dining or seating area
Highly complicated patterns can make a large patio feel busy. Material selections should support the overall landscape rather than compete with the house, furniture and gardens.
Plan Grading and Drainage Before Construction
Drainage is one of the most important parts of patio design.
The finished surface must direct water away from the house and prevent it from collecting near doors, steps, retaining walls or low areas. Downspouts, neighbouring properties, existing grades and soil conditions should all be considered.
Standard interlocking stone is not automatically permeable. Although water may enter the joints, the patio still requires the correct slope, base construction and drainage plan. Permeable paver systems are specially designed and installed differently.
Poor drainage can cause:
- Water pooling on the patio
- Settlement or movement
- Erosion around the edges
- Water flowing toward the foundation
- Ice accumulation in winter
- Damage to nearby gardens or lawn
Drainage should be part of the initial design—not something addressed after the patio has been installed.
Proper Base Preparation Makes the Difference
The pavers are the visible part of an interlock patio, but the base underneath determines how well it lasts.
A professional installation should account for:
- Existing soil conditions
- Appropriate excavation depth
- Compacted aggregate base
- Drainage and finished slope
- Bedding material
- Edge restraint
- Joint sand
- Proper compaction during installation
Cutting corners below the surface may reduce the initial cost, but it increases the likelihood of settling, shifting and uneven areas later.
When comparing quotes, ask what is included in the excavation and base preparation. Two contractors may be quoting very different installations even when the finished paver looks similar.
Integrate Steps, Walls and Walkways
A patio often needs to connect with other elevations or areas of the property.
Steps may be required at the house, while retaining walls can help manage slopes or create level outdoor rooms. Walkways can connect the patio to the driveway, side yard, pool, shed or garden.
These features should be planned together so that:
- Step heights remain comfortable and consistent
- Materials coordinate across the property
- Water moves in the correct direction
- Transitions do not feel pieced together
- Future construction will not require finished areas to be removed
Planning the patio as part of the entire landscape creates a more cohesive result.
Add Comfort and Function
Small design choices can make the patio considerably more enjoyable.
Possible additions include:
- Landscape lighting along steps and walkways
- Electrical access for cooking or entertainment
- Shade from a pergola or pavilion
- Privacy screening
- Raised planters or garden borders
- Built-in seating
- Gas service for a barbecue or fire feature
- Space for outdoor storage
- Planting that provides seasonal colour without crowding the patio
Electrical, gas and structural requirements should be considered before the interlock is installed. Adding them afterward can mean lifting or cutting into a finished patio.
Think About Maintenance
Interlock patios are relatively easy to maintain, but they are not maintenance-free.
Routine care may include:
- Sweeping away leaves and organic debris
- Cleaning spills before they stain
- Controlling weeds or moss if material accumulates in the joints
- Replacing joint sand when necessary
- Correcting isolated settlement
- Replacing individual damaged pavers
Pressure washing should be done carefully because aggressive washing can remove joint sand or damage the paver surface.
Sealing is optional for many interlock products. It may help with stain resistance or colour enhancement, but it should only be applied when appropriate for the specific paver and installation.
How Much Does an Interlock Patio Cost?
The cost of an interlock patio depends on much more than its square footage.
Major cost factors include:
- Site access
- Excavation and disposal
- Soil and drainage conditions
- Patio size and shape
- Paver selection
- Borders and detailed patterns
- Steps and retaining walls
- Lighting or outdoor features
- The amount of base preparation required
A simple, accessible rectangular patio will generally cost less than a multi-level outdoor living space with premium pavers, walls, steps and integrated features.
A detailed quote should clearly identify the project scope, materials and preparation rather than relying only on a general square-foot allowance.

Interlock Patio Planning Checklist
Before approving the final design, confirm:
- The patio is large enough for the intended furniture and activities
- Doors, gates and stairs have proper clearance
- Walking routes are comfortable
- Finished elevations work with the home
- Water will drain away from buildings
- Downspouts and existing drainage have been considered
- The paver complements the house
- Steps, borders and walls are coordinated
- Lighting, gas and electrical needs are planned
- Future landscape or pool projects have been considered
- The quote explains excavation and base preparation
Addressing these details before construction helps avoid expensive compromises later.
