Your home’s curb appeal can be improved and a welcoming entrance can be created by adding a semicircular concrete porch. This style of porch offers a distinctive appearance by fusing contemporary architecture with useful outdoor space. A successful project depends on your ability to understand the construction process, regardless of whether you’re an experienced do-it-yourselfer or intend to hire a contractor.
Planning and designing is one of the first stages in constructing a semicircular concrete porch. It is necessary to ascertain the precise measurements and form, making sure that it complements the general design of your house. In addition, proper planning takes drainage, ground conditions, and any required local authority permits into account.
Setting up the location is the next step after creating a strong plan. To hold the concrete in place, this entails laying out the area, digging a hole, and erecting a sturdy formwork. For the porch to be stable and long-lasting, the site must be properly prepared in order to avoid problems like uneven settling or cracking over time.
The crucial step of pouring the concrete calls for close attention to detail. Important steps that affect the porch’s durability and final appearance include evenly mixing the concrete, smoothing the surface, and pouring it. It’s also crucial to give the concrete enough time to cure since this guarantees that the porch will endure the elements and regular use.
A simple porch can be made into a beautiful feature of your house with the addition of finishing touches. Your porch can be made to be both fashionable and functional by adding ornamental elements like stamped patterns, colored concrete, or even integrated steps and railings. A semicircular concrete porch can be a charming addition to your home’s exterior with the correct approach.

Advantages and disadvantages of a concrete porch
Working with concrete has only one drawback: the installation process takes a long time. Installing formwork for each step is advised if multiple steps are assumed. Furthermore, concrete requires time to solidify.
Concrete structures, however, have numerous benefits:
- Increased mechanical strength, and accordingly a longer service life. In this regard, brick and wood are very inferior to concrete.
- Concrete is not subject to rotting or corrosion.
- Due to reinforcement, its strength is significantly increased.
- Concrete is not affected by ultraviolet rays. It is resistant to aggressive environmental influences.
- This material can easily be used to create structures of various shapes.
- Compared to a brick or wooden porch, a concrete building will cost much less.
- The material is resistant to fire.
- A variety of materials (including wood) can be used to finish concrete.
Concrete is simpler to work with. It doesn’t require intricate project calculations or carpentry skills. A person who lives far from construction sites could still construct such a porch with ease.
Porch design
When drawing the porch of the future, it’s important to consider the following factors:
- The width of the semicircular porch (stairs) should be at least 80-85 cm. It is considered that this is the optimal parameter for free movement of 1 person. Or you can navigate by the door. In this case, the width of the upper part of the semicircular staircase should be 50 cm wider. Also, the width of the staircase should fully correspond to its diameter.
- The staircase should be mounted at an angle of 45 degrees (less is possible). The angle of inclination of each step should be no more than 5 degrees, the height is 12-20 cm. In this case, one step can hang over another by no more than 30 mm.
Practical! It is required that the steps have a certain slope. Strict horizontality is very hard to maintain. In the event that you disregard this guideline, a reverse slope is likely to develop. As a result, you’ll notice that water starts to collect on the steps after it rains. It will eventually find its way into the grout’s tiny cracks and gather beneath the tiles. Water expands in the winter, which increases the risk of damage to the finish and the concrete base itself. Furthermore, stepping on frozen water on the stairs is dangerous.
- There should be an odd number of steps. You can clarify their number by dividing the height of the stairs themselves (the distance from the ground to the top point) by the height of one step.
- The difference between the entrance door and the upper platform of the porch can be no more than 50 mm. In this case, the platform must be calculated so that a person can freely open the door.
It turns out that the porch platform’s diameter will be at least 120 cm if the door’s width is 70 cm. It is advised to enlarge the upper step by roughly 25 to 30 centimeters on each side (in relation to the platform’s diameter). Regardless of how many steps there are, the upper step’s diameter should be 190 cm if our platform measures 130 cm. Including the inclination angles and other factors, the diameter of the lower step should already be 250 cm.
Practical! In order to expedite the process, locate the central point, which is typically the door frame’s center, and use a compass embedded in it to draw a semicircle connecting the two walls. You can draw each staircase using a similar method, increasing the radius by 26–30 cm.
Constructing a semicircular concrete porch is a worthwhile project that adds a strong, fashionable outdoor area and improves the curb appeal of your house. From planning and site preparation to concrete pouring and finishing, this guide covers all the necessary steps. Whether you’re a novice builder or an experienced do-it-yourselfer, we’ll provide you with step-by-step instructions and useful advice to help you produce results that look professional. Prepare to update your entryway with a stunning, long-lasting semicircular porch.
Construction stages
The first step in building a semicircular porch is marking and clearing the space. The points at which new steps will start must be identified. Installing pegs at these locations and connecting them with extra pegs is necessary; the more pegs you use, the easier it will be to form the ideal semicircular shape. It is necessary to pull a rope between the pegs.
In order to prepare the base, a pit that is 70 cm deep must be dug out of the wall. Sand and crushed stone are used to fill the resulting pit; each layer is 20 cm high. A cushion of this kind needs to be filled with water and gently pressed down. You can then move on to the formwork after this.
Construction of formwork
Formwork is best suited for sheet iron. Cutting and bending it into the desired shape is simple. It is sufficient to install 50×50 mm stakes in order to secure the sheets on the exterior. After the concrete mortar has been poured, they should be driven deeply enough to support the formwork. Additionally, the stakes need to be inserted 10–20 cm below the pit that was previously prepared. They are separated by roughly 45 to 50 centimeters.
The step height and the formwork height ought to be equal. The prepared form is reinforced with two layers joined by vertical elements. An Ø65 mm cross-section for the reinforcement is ideal.
Pouring concrete
It should be considered that the porch should be attached to the house’s foundation if it is constructed after the house has been constructed and is up and running. To carry out this:
- A layer of waterproofing must be laid between the foundation of the building and the future porch. For this, roofing felt coated with a water-repellent solution is suitable.
- Holes must be drilled in the foundation of the building and reinforcement must be fixed in them.
The concrete mortar is now being prepared. It is preferable to use a concrete mixer or purchase ready-made concrete if you want the stairs to last for a long time. Sand, crushed stone, and Portland cement M400 can all be used to create a mixture that works just as well if you want to cut costs. Once everything is prepared, you must pour the first step, or the base of the stairs, all at once. For a minimum of six days, the solution needs to dry. You can use the same technology to create the next step once it reaches a sufficient strength.
Practical! Once the concrete has been poured into the frame, it needs to be punctured multiple times with a stick. By doing this, voids won’t form and the base will become more sturdy and dependable.
You must compute the amount of concrete required for each semicircular step in order to get the volume. Here’s the formula we use for this:
Where V is the cylinder’s volume, S is its base’s area, h is its height, π is the number Pi, or 3.1415, and r is its radius.
