Construction of a garage at 4 cars - a task that requires careful consideration of each stage: from site selection to finishing. This project is relevant for families with several cars, car enthusiasts involved in the repair or resale of vehicles, as well as for small businesses (for example, car services or car sharing). The main difficulty lies in the optimal distribution of space: you need to take into account not only the dimensions of the machines, but also areas for storing tools, a possible workshop or even a shower for workers.
In this article we will look at regulatory requirements for garages for 4 cars, we offer 3 ready-made projects with drawings and dimensions, and also reveal the nuances of construction - from the foundation to ventilation. We will pay special attention typical mistakes, which lead to budget overruns or operational inconvenience. For example, many people forget about minimum width of gates (3 meters per car) or underestimate the importance fire breaks between boxes.
If you are planning a garage as part of a residential complex or for commercial use, be prepared for additional approvals from architectural committees. But for a private house on your own site, the process is simplified - it is enough to comply with SNiPs and local building codes. Next, let's look at everything in order.
1. Regulatory requirements and approvals
Before designing a 4-car garage, be sure to research SNiP 21-02-99 (fire safety) and SP 54.13330.2016 (residential buildings). These documents regulate:
- 📏 Minimum distances between garages: at least 6 meters for stone structures and 10 meters for wooden ones.
- 🚪 Gate width: from 3 meters per parking space (for comfortable entry Ford F-150 or Mercedes Sprinter).
- 🔥 Fire breaks: if the garage is adjacent to the house, the wall should be made of non-combustible materials (brick, concrete).
- 🌿 Fence distance: at least 1 meter (for ease of maintenance of the roof and gutters).
To build a garage for 4 cars no permission required, if:
- The area does not exceed 500 m².
- The building is not intended for commercial activities (for example, a car service center with clients).
- The site is located in the individual housing construction zone (individual housing construction).
⚠️ Attention: If the garage will be used as STO (service station), required transfer of land to the category "for entrepreneurship" and approval by Rospotrebnadzor. This increases the budget by 30-50% due to additional requirements for ventilation, sewerage and electrical wiring.
For private garages, the notification procedure is sufficient: submit a declaration to the local administration before construction starts and after its completion. In the declaration you indicate:
- Building area.
- Wall and roof materials.
- The presence of an inspection pit or basement.
2. Optimal garage sizes for 4 cars
The minimum garage dimensions are calculated based on car dimensions + passages between them. For comfortable use, we recommend the following parameters:
| Vehicle type | Length (m) | Width (m) | Minimum garage height (m) |
|---|---|---|---|
| Passenger car (Toyota Camry, Skoda Octavia) | 4.8–5.0 | 1.8–2.0 | 2.2 |
| Crossover (Kia Sorento, Hyundai Santa Fe) | 4.7–5.1 | 1.9–2.1 | 2.3 |
| Minivan (Volkswagen Multivan) | 5.0–5.3 | 1.9–2.2 | 2.4 |
| SUV (Land Cruiser 200) | 5.0–5.5 | 2.0–2.3 | 2.5 |
Based on these data, minimum garage size for 4 cars (excluding workshop and storage):
- 📏 Length: 10–12 meters (2.5–3 m per car + 1 m for aisles).
- 📐 Width: 7–8 meters (1.8–2 m per car + 1 m per aisle between rows).
- ⬆️ Height: 2.5–3 meters (for installing shelves or a lift).
If you are planning a viewing hole or basement, increase the depth of the foundation by 1.5–2 meters. This is relevant for regions with soil freezing below 1.2 m (for example, Moscow, St. Petersburg).
Make a margin of 0.5 m in length for the trunk or open hood|
Check the width of the gates (minimum 3 m per machine)|
Consider the ceiling height for installing shelving or a lift|
Provide space for tools and spare parts (1.5–2 m²)|
Leave a passage of at least 1 m between machines for comfortable access -->

4. Selection of materials: which is cheaper and more reliable?
Depends on materials garage durability and heating costs. Let's look at the pros and cons of popular options:
| Material | Cost (per m²) | Pros | Cons |
|---|---|---|---|
| Foam blocks | 1 200–1 500 ₽ | Lightweight, good thermal insulation, quick installation. | Requires finishing (plaster, siding), is afraid of moisture. |
| Brick | 2 000–2 500 ₽ | Durable, non-flammable, durable (50+ years). | Expensive, requires a reinforced foundation. |
| Metal frame (LSTK) | 1 800–2 200 ₽ | Can be assembled in 2-3 weeks, light weight. | Low thermal insulation (needs insulation), risk of corrosion. |
| Wood (timber, frame) | 1 500–2 000 ₽ | Eco-friendly, quick installation. | Fire hazardous, requires treatment with an antiseptic. |
For economy option foam block or LSTK with insulation is optimal Rockwool (thickness 100 mm). If your budget allows, choose brick - it will last for decades without repair.
Roof: suitable for snowy regions (Ural, Siberia) gable with an inclination angle of 30–45°. In the southern regions there is enough single-slope (slope 10–15°).
⚠️ Attention: When using corrugated sheets or metal tiles be sure to lay it down waterproofing membrane (for example, Tyvek). Without it, condensation will destroy the insulation in 2–3 years.
5. Ventilation and heating: how to avoid dampness and rust?
Poor ventilation is the main reason body corrosion and mold appearance in the garage. Consider 3 systems suitable for a 4-car garage:
1. Natural ventilation
Suitable for garages up to 50 m². Operating principle: air enters through inlet openings at the bottom of the walls and exits through exhaust pipe on the roof.
Pros: cheap (from 10 thousand rubles), does not require electricity.
Cons: ineffective in winter (due to low air temperature).
2. Supply and exhaust ventilation with fans
Ideal for garages of 50–100 m². Includes:
- 🌀 Supply fan (installed in the wall at a height of 0.5 m).
- 🌀 Exhaust fan (on the opposite wall at a height of 2 m).
- 📊 Timer or humidity sensor to turn on automatically.
Cost: 30–50 thousand rubles. (depending on fan power).
3. Heat recovery system
Suitable for heated garages. The recuperator heats the incoming air using exhaust heat, which reduces heating costs by 30–40%.
Pros: energy efficiency, no drafts.
Cons: high cost (from 100 thousand rubles).
Heating: for a garage for 4 cars are optimal:
- 🔥 Diesel gun (heats quickly, but is noisy and requires ventilation).
- 🔌 Infrared heaters (silent, heat objects, not air).
- 🧯 Water heated floor (expensive installation, but low operating costs).
For garages in cold regions, use combined system: infrared heaters + recovery ventilation. This will allow you to maintain a temperature of +10°C in winter without high energy costs.
6. Typical mistakes during construction and how to avoid them
Even experienced builders make mistakes that later cost a lot of money. Here TOP-5 misses and ways to prevent them:
- Wrong foundation.
If the soil is heaving (clay, loam), the strip foundation may crack in winter. Solution: use pile-grillage or slab foundation
- Saving on waterproofing.
Without waterproofing the floor and walls, moisture will penetrate into the insulation, which will lead to mold. Solution: use bitumen mastic or penetrating waterproofing (for example, Penetron).
- Narrow gate.
Gates 2.5 m wide are not suitable for Ford Ranger or Toyota Land Cruiser with mirrors. Solution: make the gate no narrower than 3 m per car.
- Lack of headroom.
If the height of the garage is 2.2 m, you will not be able to install shelving or a lift. Solution: minimum height - 2.5 m, optimal - 3 m.
- Bad electrical wiring.
Using regular sockets for a welding machine or compressor will result in a fire. Solution: pave separate lines for powerful equipment with RCD.
If the garage will be used as a workshop, be sure to provide three-phase network (380 V) - this is required by most professional tools.
The most expensive mistake is the wrong foundation. Remaking it will cost 30–50% of the cost of the entire garage. Always order geological soil surveys before starting construction!
7. How much does it cost to build a 4-car garage?
Construction cost depends on materials, sizes and trim level. Here are the calculations for three options (prices are current for 2026 for the Moscow region):
| Garage type | Area (m²) | Cost (thousand rubles) | Construction period |
|---|---|---|---|
| Economy (foam blocks, pitched roof) | 70 | 800–1 200 | 2–3 months |
| Medium (brick, gable roof, insulation) | 96 | 1 500–2 000 | 3–4 months |
| Premium (aerated concrete, basement, lift) | 126 | 2 500–3 500 | 5–6 months |
Included in price not included:
- 📄 Design and approval (30–50 thousand rubles).
- ⚡ Electricity connection (from 50 thousand rubles).
- 🚿 Sewage and water supply (from 100 thousand rubles).
You can save on:
- 🔨 Independent wall laying (saving up to 20%).
- 🛠️ Purchasing materials in bulk (10-15% discount).
- 📅 Construction during the off-season (in autumn or spring it is cheaper to hire a crew).
⚠️ Attention: If you hire a crew, be sure to sign contract indicating the terms and stages of payment. Paying “in words” often leads to delays in work or poor quality results.
FAQ: Answers to frequently asked questions
Is it necessary to approve a garage for 4 cars if it is on its own site?
Sufficient for a private garage up to 500 m² notification procedure: you submit a declaration to the administration before the start of construction and after its completion. If the garage will be used as STO or for business, you will need building permit and transfer of land to the commercial category.
What is the best foundation for a 4-car garage with a basement?
Ideal for a garage with a basement monolithic slab foundation 20–25 cm thick. It evenly distributes the load and protects against soil heaving. Alternative - pile-grillage foundation (cheaper, but requires accurate calculation of piles).
Is it possible to build a garage for 4 cars from a metal frame?
Yes, but please note:
- 🔹 The frame needs to be insulated (mineral wool or polyurethane foam).
- 🔹 Make interior decoration from non-combustible materials (for example, DSP).
- 🔹 Service life - 20–30 years (versus 50+ for brick).
Which ventilation should I choose for a 4-car garage?
Optimal for a garage with an area of 70–100 m² supply and exhaust system with fans. If your budget is limited, install natural ventilation (supply openings + exhaust pipe), but supplement it moisture absorbers (for example, Silica Gel).
How long does it take to build a 4 car garage?
The timing depends on the type of construction:
- 📅 Metal frame: 2–3 weeks.
- 📅 Foam blocks/aerated concrete: 1.5–2 months.
- 📅 Brick: 3–4 months (due to laying and drying time).
