What is a double garage?

A double garage is a covered parking space with side walls. It offers space for two vehicles parked side by side. Access is usually via two separate garage doors or one large double door.

Double garages are constructed as prefabricated garages made of concrete or steel. Alternatively, brick constructions are also possible. The range of applications is versatile.

A double garage is suitable for:

• Households with two or more vehicles
• Families with space for bicycles and garden tools
• Use as a workshop or storage room (depending on local building regulations)
• Shared use with neighbours

A double garage is particularly worthwhile if there is sufficient space on the property. It also offers long-term protected parking space. The shared construction method results in lower costs per parking space than two separate single garages. In addition, a high-quality garage increases the property value and improves the overall appearance.

Double garage costs – current price overview 2026

The cost of a double garage varies considerably depending on the type of construction, fittings and region. When considering the price, it is important to distinguish between the cost of the garage itself and the total cost including foundations and installation.

Typical total costs in 2026 (including foundations and installation):

A prefabricated concrete double garage costs around 16.000 € in total. Depending on the fittings and region, the costs can reach up to 34.000 €. Steel double garages cost between 14.000 € and 29.000 €. However, they offer less insulation and durability.

A brick double garage costs between 25.000 € and 40.000 €. However, it offers individual design options. It can also be optimally adapted to the existing building.

Cost overview by type of construction (total price in 2026):

The price ranges take into account different equipment options and regional differences. Foundation work costs an additional 3.000 to 6.000 €.

Many suppliers offer package prices that include delivery. However, the following additional costs may apply: mobile crane (costs vary greatly depending on the construction situation and accessibility), road closure costs (approximately 150 to 400 €) and no parking signs (approximately 50 to 150 €).

Note: The prices quoted correspond to the market level in 2026. Specific offers may vary depending on the manufacturer, region and individual configuration. You should therefore obtain several comparative quotes.

Costs by construction type in detail

Prefabricated double garage made of concrete

Prefabricated concrete garages are the most popular choice for double garages in Germany. They are prefabricated in elements at the factory. They are then assembled on the prepared foundation within a day. The concrete construction guarantees high stability and a service life of over 50 years. It also offers good fire protection.

Pricing for concrete double garages:

• Standard garage only: from 12.000 €
• Garage with additional equipment: 16.000 to 20.000€
• Foundation and earthworks: 3.000 to 6.000 € extra
• Delivery and assembly: 800 € to 1.500 € extra
• Typical total cost: 16.000 to 34.000 €

For higher-quality designs with insulated walls or special roof shapes, prices are at the upper end of the range. Assembly is carried out by qualified personnel. The prefabricated elements are erected by crane and connected to each other. Some suppliers of prefabricated garages deliver the garage to the construction site fully assembled. Some even have their transport vehicles, which simplifies logistics and saves costs for external crane companies. This is precisely the case at ZAPF – we deliver and assemble your garage with our own special vehicles.

Steel double garage

Prefabricated steel garages are often delivered as kits. The structure consists of galvanized sheet steel mounted on a metal frame. They are cheaper than concrete or stone garages. However, there are some disadvantages to consider.

Pricing for steel double garages:

• Garage kit only: from 8.000 €
• Garage with better finish: 11.000 to 17.000 €
• Foundation and earthworks: additional 2.500 to 5.000 €
• Delivery and assembly, if applicable: additional 500 to 2.000 €
• Typical total cost: 14.000 to 29.000 €

Steel garages offer little thermal insulation and are prone to condensation. They also have lower burglary protection. Their service life is around 20 to 30 years. This is significantly less than that of concrete or stone garages. Concrete double garages are preferable for a permanent solution that increases the value of the property.

Brick double garage

A custom-built brick double garage offers maximum design freedom. It can be perfectly adapted to the architecture of the house. It is constructed from bricks, sand-lime bricks or concrete blocks. It can also be designed with different plaster and façade options.

Pricing for brick double garages:

• Brick shell: 16.000 to 22.000
• Foundation and floor slab: 4.000 to 7.000 €
• Roof construction: 5.000 to 8.000 €
• Plaster and façade: 3.000 to 5.000 €
• Garage doors: 2.000 to 6.000 €
• Typical total cost: 25.000 to 40.000 €

Depending on the weather, construction takes four to eight weeks. In addition, there are costs for architects or construction managers, if these are required. The biggest advantage of brick garages is their individual design. They also offer excellent thermal insulation and an extremely long service life of over 70 years.

Double Garage

The standard dimensions for a double garage are 6 x 6 metres (width x depth). This offers sufficient space for most cars. Nevertheless, you should also take future vehicle changes into account when planning. Standard double garages have a width of 5 to 8 metres and a length of 5 to 9 metres.

Recommended minimum dimensions by vehicle type:

When planning, you should bear in mind that there should be at least 60 centimetres between the two vehicles. This allows the doors to be opened comfortably. A distance of 40 to 50 centimetres from the outer walls is recommended. In Bavaria, for example, a minimum width of 2.40 metres per parking space in a double garage applies.

The clearance height should be at least 2.0 metres. For larger vehicles or if roof racks are frequently left mounted, 2.25 to 2.5 metres is advisable. Modern prefabricated garages offer a standard interior height of 2.20 to 2.50 metres.

Additional costs for a double garage

In addition to the basic price for the garage construction, there are other costs to consider. These must be considered when planning your budget.

Foundation for a double garage: A frost-proof floor slab is required for every garage. The cost of a concrete foundation for a double garage is between £2,500 and £5,000. The soil conditions and the required thickness are decisive factors here. Additional earthworks may be necessary if the building site is difficult. Drainage is sometimes also required. This costs an additional £1,000 to £2,500.

Special feature of ZAPF garages: ZAPF precast concrete garages require strip or point foundations made of concrete – a continuous floor slab is not necessary as the garage floor is already in place. This saves on materials and costs. The foundations can optionally be laid in advance by ZAPF specialists. Alternatively, it is possible to lay the foundations yourself according to ZAPF specifications or have them laid by a third party. With the informative and clear documentation provided by ZAPF, this is feasible for handy DIY enthusiasts. It is important that the foundations are sufficiently dimensioned and have enough time to set before the solid precast concrete garage is erected. Further details can be found on the ZAPF page ‘Delivery and assembly’, where two informative videos are also available.

Assembly and delivery: For prefabricated garages, transport costs of 800 to 2.500 € must be taken into account. These depend on the distance to the manufacturer’s factory. Crane costs vary greatly depending on the construction situation. In simple circumstances, the costs can be around 500 to 1.200 €. However, if a special crane with a lifting capacity of 250 tonnes, for example, is required due to difficult access or special circumstances, the costs can be significantly higher. Some suppliers offer package prices that include delivery and standard installation. Nevertheless, any additional costs for special construction situations should be clarified in advance.

Garage doors: Standard up-and-over doors are usually included in the basic price. Higher-quality sectional doors with electric drives cost an additional 2.000 to 3.500 € per door. These offer greater convenience and optimal use of space, as they disappear under the ceiling. For two doors, you should therefore budget 4.000 to 7.000 € for the premium version.

Electrical and special equipment: Basic installation with light switches and sockets costs around 600 to 1.000 €. For more extensive electrical work, you should budget 1.500 to 3.500 €. This includes lighting, wall connections, or the installation of a wall box for electric vehicles.

Double garage approval and regulations in Germany

Whether a building permit is required for a double garage depends on the federal state. Local building regulations also play a role. The regulations vary considerably.

Permit-free garages: In many federal states, garages can be built without a building permit under certain conditions. In Bavaria, for example, garages with a floor area of up to 50 square metres are exempt from the permit requirement under certain conditions. A standard double garage measuring 6 × 6 metres has an area of approximately 36 square metres. This means that it could, in principle, fall into this category.

Important to note: Exemption from the permit procedure does not mean exemption from regulations. Even without a permit procedure, all building regulations must be complied with. These include boundary distances, maximum wall heights and local design specifications.

When is a permit required?

• If the floor space is exceeded (e.g., over 50 m² in Bavaria)
• If located in certain protected areas
• If the development plan stipulates this
• For extensions to existing buildings

Important distances and regulations:

• At least 2.5 to 3 metres from the property boundary (depending on the federal state)
• Special regulations must be observed for boundary construction
• Additional requirements may apply in development plan areas
• Roof shape and façade design often require approval

Before building a double garage, you should always submit a preliminary building application to the relevant building authority. Alternatively, you can apply for approval directly. The processing time is usually four to eight weeks. Many garage manufacturers offer assistance with the application process.

Prefabricated garage or brick-built double garage – comparison

Several factors play a role when deciding between a prefabricated garage and a brick-built double garage. Both options have their specific advantages and disadvantages.

Costs: A prefabricated double garage made of concrete costs between 14.000 and 30.000. € This is usually cheaper than brick garages, which cost between 20.000 and 30.000 €. The price advantage lies primarily in industrial prefabrication. In addition, the amount of work required on site is lower. The savings can amount to 5.000 to 10.000 € for comparable basic equipment.

Practical tip: With the ZAPF savings calculator, you can calculate when a ZAPF prefabricated concrete garage will pay off for you and how much you will save compared to other types of construction.

Construction time: The biggest advantage of prefabricated garages is the extremely short construction time. Once the foundation has been prepared, assembly takes place within a day. Brick garages require four to eight weeks of construction time. Added to this are the drying times for plaster and screed. This extends the total construction time to up to ten weeks.

Quality and service life: High-quality precast concrete garages have a service life of over 50 years. This means that they are almost as stable as brick garages. However, brick garages offer advantages in terms of thermal insulation. They also allow for perfect visual coordination with the residential building. The service life of brick garages is over 70 years.

For most builders, prefabricated concrete garages offer the best value for money. They are robust, durable and ready for use in a short timeframe. Brick garages are mainly worthwhile for special architectural requirements. Or if the garage is to be built directly onto the house.

Double garage with flat roof and other roof shapes

There are various roof shapes to choose from for double garages. Each has its own specific advantages.

Double garage with flat roof: The flat roof is the most common option for prefabricated garages. It is inexpensive and allows for green roofing. It can also serve as additional usable space. Proper drainage is important here. In addition, the waterproofing must be maintained regularly. The cost of a flat roof is approximately 850 to 1.500 € less than that of a gable roof.

Monopitch roof: This roof shape offers a modern design. It allows for good water drainage and can be equipped with photovoltaic modules. The slope is usually between 5 and 15 degrees. The additional cost compared to a flat roof is around 450 to 900 €.

Gable roof: The classic gable roof fits well with traditional buildings. It offers additional storage space in the roof area. However, it is more expensive to construct than a flat roof. The additional costs are around 1.500 to 3.000 € compared to a flat roof.

The choice of roof shape should match the architecture of the main building. Local building regulations must also be observed. In some development plan areas, the roof shape is prescribed.

Double garage with equipment room – practical extension

A double garage with equipment room offers additional storage space for tools, garden tools and leisure equipment. This leaves the actual garage area free for vehicles. The equipment room is usually attached to the side or planned as an integrated area.

Advantages of a double garage with equipment room:

• Separate storage of vehicles and equipment
• More order and clarity
• Protection of sensitive equipment from the weather
• Increased property value

Depending on its size, a tool room costs between 1.500 and 5.000 € extra. It can either be built as an extension or integrated directly into the garage structure. When planning, you should allow sufficient space for shelves and workbenches.

A typical equipment room measures 2 × 3 metres. This provides sufficient space for lawnmowers, bicycles and tools. A separate door can also facilitate access, meaning you don’t have to go through the garage. This additional door costs around 600 to 1.200 €.

Frequently asked questions about double garages (FAQ)

How much does a double garage with foundations cost in total?

A prefabricated concrete garage including foundations and installation, typically costs between 14.000 and 30.000 €. A brick double garage with foundations costs between 22.000 and 35.000 €. The exact costs depend on the fittings, type of door, and regional prices. Make sure that all costs are included in the quotes.

What are the ideal dimensions for a double garage?

The standard size of 6 × 6 meters is sufficient for two mid-range cars. For larger vehicles or if additional storage space is required, dimensions of 6.5 × 6.5 or 7 × 7 metres are recommended. For a double garage with a tool room, you should plan for at least 7 × 6 meters.

When do I need a permit for a double garage?

The permit requirement depends on the federal state. In Bavaria, garages up to 50 square metres may be exempt from the permit requirement under certain conditions. A standard double garage measuring 36 square meters could therefore be exempt from the permit requirement. Nevertheless, all building regulations must be complied with. Clarify this in advance with your building authority.

Can a double garage be extended at a later date?

With prefabricated garages, subsequent extensions are only possible to a limited extent. However, you can add a utility room or extension to the side. If you are planning an extension, this should be taken into account in the initial planning stage.

Double garage with flat roof or gable roof – which is better?

A flat roof is more cost-effective and allows for green roofing. It is the most common choice for prefabricated garages. A gable roof offers more storage space and is more suited to traditional buildings. The choice should match the architecture of the main building.

How long does a concrete double garage last?

A high-quality prefabricated concrete garage has a service life of over 50 years. This assumes regular maintenance and care. Brick garages can last over 70 years. Steel double garages last around 20 to 30 years.

Conclusion & decision-making aid

A double garage is a sensible investment for households with two vehicles or increased space requirements. Prefabricated concrete garages offer the best value for money. With a total cost starting at around 17.000 €, a short construction time and a long service life, they are the most popular choice.

A brick double garage is more expensive, starting at around 22.000 €. However, it allows for individual design and perfect integration into the building’s architecture. If you need additional storage space, a double garage with a utility room is the ideal solution.
