Planning the construction of a parking space is a fundamental stage on which the durability of the entire structure and ease of use depend. Dimensions of 6 by 4 meters are considered the “gold standard” for a private motorhome, since such an area allows you to accommodate not only passenger vehicles, but also a full-fledged workshop or storage area. Properly composed drawing of a 6 by 4 garage takes into account not only the external dimensions, but also the thickness of the walls, the type of foundation and the location of the gate, which is critical for avoiding errors when purchasing materials.
Many site owners mistakenly believe that they can do without detailed design documentation, relying on the experience of neighbors or general ideas about construction. However, ignoring engineering calculations often leads to budget overruns, frame deformation, or problems with gate opening in winter. In this article, we will analyze the technical nuances of creating a reliable shelter for your car, based on current building codes and practical experience.
The choice between brickwork, foam blocks or a metal frame must be made before digging a pit begins. Each material has its own requirements for foundation and weight load, which directly affects the final estimate. Below we will look at the design stages in detail so that you can create a working design yourself or competently supervise the work of contractors.
Selecting the type of construction and materialsThe first thing any project begins with is determining the construction technology. For dimensions of 6x4 meters, three options are most common: a permanent structure made of blocks, a metal shell garage or a combined frame. Capital structures require strip foundation and have high thermal insulation, which turns the garage into a full-fledged workshop.
Metal structures are built faster, but require high-quality anti-corrosion treatment and additional insulation if you plan to stay inside in winter. Frame technologies make it possible to combine installation speed and good thermal insulation properties using sandwich panels or corrugated sheets with insulation.
When choosing wall material, it is important to take into account the climate zone and groundwater level. For example, aerated concrete requires mandatory external finishing to protect against moisture, whereas corrugated sheet It is resistant to precipitation, but cools quickly.
Site analysis and foundation preparationGeodetic preparation of the area is a critical stage that cannot be ignored. Before transferring garage dimensions to the area, it is necessary to remove the fertile layer of soil and determine the level of groundwater. If the water comes close to the surface, you will need to install a drainage system or choose a slab foundation that will act as a floor.
For a permanent structure made of blocks or bricks, the ideal solution would be a recessed strip foundation. The width of the tape is usually 40-50 cm, and the depth depends on the freezing of the soil in your region. It is important to strictly observe the geometry of the corners, using the “Egyptian triangle” method or a laser level, so that the walls lie evenly.
⚠️ Attention: Never skimp on foundation waterproofing. Capillary rise of moisture can destroy garage walls within a few seasons, even if a moisture-resistant block is used.
When choosing a metal garage, a columnar foundation or prefabricated reinforced concrete slabs are often used. This speeds up the process, but requires a perfectly level area. Preparation of the base includes pouring a sand and gravel cushion at least 15-20 cm thick with mandatory compaction.
Detailed specification and calculation of materialsFor a garage measuring 6 by 4 meters along the outer perimeter, the floor area will be 24 square meters. However, if we take into account the internal usable area with a wall thickness of one block (40 cm), the dimensions will decrease to approximately 5.2 by 3.2 meters. Accurate calculation of materials is necessary to minimize waste and optimize delivery logistics.
Order building materials with a margin of 10-15% for breaking and trimming, especially when it comes to bricks, blocks or tiles.

Let's consider the approximate need for materials for the construction of walls made of foam blocks (standard 600x300x200 mm) with a height of 2.5 meters. The perimeter of the building is 20 meters. Subtracting the area of the gate (2.5x2.2 m) and one door (0.9x2.1 m), as well as the window opening, we obtain the net area of the walls.
Below is a table with an approximate calculation of the basic materials for a permanent garage:
| Material | Unit of measurement | Quantity (approx.) | Note |
|---|---|---|---|
| Foam block D600 | pcs. | 260-280 | taking into account trimming |
| Cement M500 | kg | 1200 | for masonry and screed |
| Reinforcement d12 | m.p. | 400 | foundation and belt |
| Corrugated roofing sheet | sq.m. | 30-32 | taking into account overhangs |
For its construction, concrete of a class not lower than B20 and a reinforcement cage are used.
Design of gates and entrance groupThe gate is the most functional and loaded element of the garage. For an opening 2.5–3 meters wide and 2.2–2.4 meters high, swing or sectional structures are most often chosen. Swing gates are easier to make with your own hands, but require free space in front of the garage to open the doors.
Sectional doors Alutech or Hörmann They save space and have better thermal insulation, but their installation requires high precision in the assembly of guides. When designing an opening, it is necessary to lay reinforced lintels made of metal channels or concrete blocks so that the upper part of the wall does not sag under the weight of the structure.
☑️ Ideal opening parameters
⚠️ Attention: When installing automatic gates, make sure that the electrical wiring is connected to the ceiling or wall in advance, before the finishing work begins.
The gate, whether built into the gate or located separately, should open outward so that in case of snow drift it can be easily opened. The width of the gate should not be less than 90 cm for convenient passage with a tool or bicycle.
Roofing and drainage systemsThe roof of a 6 by 4 garage can be single or gable. The lean-to option is cheaper and easier to implement, especially if the garage is adjacent to other buildings. The slope of the slope should be at least 10-15 degrees for effective drainage of water and snow.
For the rafter system, a board with a section of 50x150 mm or 50x200 mm is used with a pitch of 60-80 cm. A mandatory element is waterproofing membrane and a counter-lattice creating a ventilated gap. This prevents the wooden structures from rotting and the insulation from getting wet.
Features of installing a soft roof
Bituminous shingles require a continuous sheathing of OSB boards or plywood. This increases the weight of the structure, but provides excellent sound insulation and tightness even with complex roof shapes.
The drainage system includes gutters and downpipes. Even if the garage is not heated, proper water drainage protects the foundation from being washed away. Pipes should be positioned so that water flows into a storm drain or drainage ditch, and not under the walls of the garage.
Internal arrangement and utilitiesThe layout of the interior space of the garage, 6 by 4 meters, allows you to zone the room. The standard layout divides the area into a parking area, a workbench area and a storage area. For lighting, it is recommended to use a combined scheme: general overhead light and local illumination of workplaces.
The optimal ceiling height for a garage-workshop is 2.7–3.0 meters, which allows you to install a lift for cars or high shelving.

Electrical wiring must be done openly in non-flammable cable ducts or corrugated cables, since the garage is a fire-hazardous room. Sockets are placed at a height of 1-1.2 meters, and switches are located at the entrance. If you plan to use a welding machine, the wiring is calculated with a power reserve.
Ventilation is another critical aspect. The natural supply and exhaust system ensures the removal of gasoline vapors and moisture. The entrance hole is made near the floor in the corner opposite from the gate, and the exhaust hole is made under the ceiling at the ridge of the roof.
Common mistakes when building yourselfOne of the most common mistakes is saving on foundation depth. Frozen soil can push out a lightweight structure, warping the gate and compromising the integrity of the walls. It is also often forgotten blind area around the garage, which leads to the accumulation of water near the walls and dampness inside.
Incorrect calculation of the snow load on the roof can lead to roof collapse in winter. In some regions, the load per square meter can reach 200 kg or more, which requires strengthening the rafter system. Ignoring these standards for the sake of saving materials is unacceptable.
⚠️ Attention: Do not use wooden beams without high-quality fire-bioprotective impregnation to cover the garage, especially if fuel and lubricants are planned to be stored in the room.
Another mistake is the lack of a power supply project. Twisted wires, lack of circuit breakers and the use of wires with a cross-section smaller than required often cause fires. All work must be carried out in accordance with the PUE (Electrical Installation Rules).
FAQ: Frequently asked questions
Is it necessary to register a 6 by 4 garage as a permanent structure?
If the garage has a foundation and is firmly connected to the ground, it is considered a permanent structure and requires registration with Rosreestr. Temporary metal structures (shells) usually do not require registration, but the rules may vary depending on the region and the charter of the SNT.
How thick should the walls be for an unheated garage?
For an unheated garage, the wall thickness of one block is sufficient (20-40 cm depending on the material). The main task of such walls is protection from precipitation, wind and intruders, and not heat preservation.
Is it possible to make a 6 by 4 garage from corrugated sheets without a concrete foundation?
Yes, lightweight metal garages can be installed on a prepared sand and gravel bed or finished road slabs. However, for durability and evenness of the floor, it is recommended to make at least a minimum concrete screed with a thickness of 10 cm.
What is the optimal gate height for an SUV?
For modern SUVs and crossovers with a roof rack, the optimal gate opening height is 2.3–2.5 meters. The standard 2.1 meters may not be sufficient.
