Design
The Step You Decide Not to Build
The thing to design is the route, not the shape. Car to door to seat, in the dark, carrying something, on a wet surface - and every decision follows from that walk.
A step-free patio is not really a patio decision. It is a route decision. The question is not what shape the paving is, it is whether a person can get from the car to the door to a seat while it is dark, while it is wet, and while they are carrying something in both hands. Design that journey and the patio takes care of itself. Design the shape first and the awkward bits end up wherever the shape ran out. Two things to say before anything else, because they set the boundaries of this page. We do not describe anything we build as accessible or compliant, and nothing here is a substitute for advice about a specific person - if somebody in the house has a real requirement, that gets measured on site with them, not read off an article.
Design the route, not the footprint
Most patios are drawn as an outline. Somebody picks a shape that suits the yard, the paving fills it, and the way people actually move across it is discovered afterwards. That works fine while everybody in the house is quick on their feet, and it stops working quietly, years later, without anyone deciding it has.
So start with the journey instead. Where does the car stop, and what happens between there and the door. Where is the gate, and which way does it swing. Where do people put things down. Where is the bin, the hose, the grill, the door that gets used when the front one is locked. Trace all of that on the plan before a single edge is drawn, and you will find the busy parts of the yard are not where the paving is widest.
Then do the design review nobody does. Walk the route on a wet evening with your hands full and no free hand for a rail or a door frame. That is the condition the layout has to survive, and it is remarkable how much it changes what looks obvious in daylight on a Saturday.
Where a step is avoidable, and where it is not
Some of this is genuinely not up for negotiation. The finished level where the paving meets the house is set by things that arrive already decided - the sill you step over, where the wall covering stops, and which way water has to go. Our piece on the height at the back door covers why that line cannot be argued with and why raising it is the expensive idea it does not look like.
If that level leaves you well above the ground you want to sit on, a step is the honest answer. The useful move then is to draw it as part of the patio instead of adding it at the end. A landing with a step, placed where the route naturally slows anyway, reads as intentional. A step that appeared because a level got fudged tends to land in the busiest square yard on the whole patio, which is exactly where you least want to be looking down.
Where the ground runs roughly with you rather than away from you, the picture is different. A level change that would make one abrupt step can often be spread across the length of the route instead, so the change is still there but nobody has to negotiate it in one go. That is a design choice available on a lot of Kenosha County lots and it costs nothing extra to ask about, because the fall has to be handled either way.
Flat is not free
This is the one place a step-free design can quietly go wrong, so it gets its own heading. Step-free does not mean level. Every hard surface in this climate still has to shed water away from the house, and a surface with no fall in it holds a film of water instead of moving it along.
A held film is a problem twice over. It is the slipperiest condition the surface will ever be in, and from November onwards it is the ice. Underneath, the physics has not changed either: water with nowhere to go soaks into the ground below the paving and expands the moment it freezes, which is the whole story told in why patios heave and crack here. A patio designed to be kind to somebody on their feet and built with no fall would end up neither safe nor sound.
So the fall stays. What a step-free design removes is the abrupt change, not the drainage. If anyone offers you a level patio as an answer to a mobility question, that is the moment to ask where the water is supposed to go.
Choose the surface wet, not dry
Samples get chosen indoors. They are dry, they are lit from above, and they are being looked at from waist height for their colour. None of that is the situation the surface has to perform in.
Take the sample outside instead. Wet it properly, tilt it, and put your foot on it in the shoes you actually wear in the garden. What you are reading is texture and how the face behaves with water on it, and that is a route property. A finish that goes glassy when it is wet is a legitimate thing to want for the look of it, and it is a different decision from the one about where people walk. Nothing stops you having both, as long as they are not the same square yard.
The other half of this is joints and pattern. A route surface wants a consistent, even face rather than a busy one with a lot of edges and level changes between units, and it wants joints that are full and staying full. That is upkeep as much as specification, and the marks and growth that show up on the shaded half of a patio are covered in our piece on what the stains on a paver surface mean - on a route, that growth stops being a looks problem and becomes a grip problem.
Width where it pinches, not in the middle
Patios are generous in the middle and mean at the ends. That is how they get drawn, because the middle is what people picture. But nobody has ever caught a walker on the middle of a patio.
The places routes fail are the narrow ones, and they are the same on most lots.
| Pinch point | What goes wrong there | What to settle at design stage |
|---|---|---|
| The gate | Swing, latch height and the surface either side of it | Which way it opens, and whether it can be held open |
| The corner of the house | A turn taken blind, often with a downspout in it | Room to turn, and where the downspout water goes |
| Past the air conditioning unit or meter | A fixed obstacle nobody thinks of as part of the route | Whether the paving goes around it or the route goes elsewhere |
| The turn at the back door | Stopping, turning and opening a door at the same time | Somewhere to set things down while the door is dealt with |
| Between the table and the wall | The gap disappears the moment the furniture arrives | Where the furniture actually lives, drawn on the plan |
We are deliberately not printing widths. The number that matters is the one taken at your pinch points, with the people who use them, and any figure published without seeing your yard is somebody else guessing.
Something solid to hold onto, years early
The best time to build a place for a hand is when the ground is already open and nobody needs one yet. Do it then and it is landscaping. Do it later and it is equipment, and it involves opening a finished surface to fix something into it.
It does not have to look like a rail. A seat wall running along the route, a low wall at a change of level, a solid pier at the turn, a raised bed edge at a comfortable height - all of them give a hand something to meet, and all of them are things people put in patios anyway. Our outdoor kitchen and fire pit ideas piece covers built-in structures that end up doing this job by accident, and the retaining wall page covers seat walls that are doing real work at the same time.
Light belongs in the same conversation. Level changes and turns are the places worth lighting, and any power run is a licensed trade item and dramatically easier while the base is still open. Deciding it after the last unit is laid is the expensive order to do things in.
When the requirement is a specific person
Everything above is general design thinking for a house where people intend to stay. It is not a specification, and it is not advice about a particular person.
If somebody in the household uses a chair, a walker or a stick, or has a condition affecting balance or vision, the requirements are theirs rather than generic. An occupational therapist can look at the real route, watch the person use it, and produce measurements that mean something. Bring those to the design stage and a good builder will work to them. Skip that step and the patio is built to an idea of what somebody needs, which is not the same thing and is a great deal harder to correct once the paving is down.
If you want to see how we approach layout in general, the patios page covers the build, and the walk-through is the point at which every one of these decisions is cheapest to make.
