A carport with a garden shed protects your car and creates valuable storage space. But the costs can quickly exceed 10,000 euros. Discover how to find the right financing for your building project and benefit from government schemes.
The topic in brief and concise terms
The total costs for a carport with a storage shed usually range between €3,000 and €15,000, depending on the material and how much of the work you do yourself.
A home improvement loan is often available to property owners at a lower interest rate than a flexible instalment loan.
The requirement for a building permit depends on your federal state; an enquiry with the building authority is always required.
Cost analysis: The actual costs for your construction project
The total cost of a carport with a storage shed is made up of several items. Simple timber kits start at around 2,500 euros. For more durable aluminium models, you should budget at least 4,000 euros. There are also costs for the foundations, which vary depending on size and ground conditions and range between 500 and 1,500 euros. Many underestimate the additional costs of installation by specialist contractors, which often amount to 20 to 30 per cent of the kit costs. A double timber carport with a 10-square-metre shed can quickly reach 12,000 euros including all ancillary costs. Careful planning of these costs is the first step towards solid financing for your carport. The choice of the right financing route depends heavily on this calculation.
Financing options compared: instalment loan, home improvement loan and building savings
There are mainly three ways to finance your carport. The classic personal loan offers maximum flexibility, as it is not tied to a specific purpose and covers amounts up to EUR 75,000. A home improvement loan is often cheaper in terms of interest, but usually requires you to own a property and is purpose-specific. The difference in interest rates can be as much as two percentage points. A third option is an existing building savings contract, which offers favourable loan interest rates once allocated. Here is an overview of the most common options:
Personal loan: Ideal for tenants or for amounts under EUR 10,000, as the process is straightforward.
Home improvement loan: The best choice for property owners, often with interest advantages of one percentage point or more compared with personal loans.
Home loan without land registry entry: Many banks offer loans of up to EUR 50,000 without the costly land registry entry.
Building savings loan: Makes sense when planning well in advance, as the savings phase can take several years.
Our expert tip: Compare the effective interest rates from at least three different providers to save several hundred euros. A loan for unrestricted use gives you the flexibility you need for unforeseen costs. Next, we will check whether government grants can reduce your costs.
Check government funding: grants for e-mobility and sustainability
Government grants can significantly reduce the costs of your project. Particularly relevant was the KfW programme “Solar power for electric cars (442)”. This programme offered grants of up to €10,200 for the combination of a photovoltaic system, battery storage and wallbox. A carport with a south-facing orientation was often the ideal structural prerequisite for this. However, the funding allocated to this programme was exhausted within a few hours in the past and is currently suspended for 2024 and 2025. It is advisable to regularly check the KfW website for a possible relaunch. Independent of federal programmes, some local authorities and federal states offer their own grants for the installation of wallboxes or green roofs on carports, often amounting to €200 to €500. It may be worth checking with your local authority. A modernisation loan for energy-efficient refurbishment can be an alternative if you are planning further alterations. Before construction begins, however, the legal framework must be clarified.
Overcoming legal hurdles: understanding planning permission and neighbour law
The need for planning permission is the most common legal hurdle when building a carport. The regulations vary greatly across the 16 federal states. In Bavaria, covered parking spaces of up to 50 square metres are often exempt from planning permission. In North Rhine-Westphalia, this limit is just 30 cubic metres of enclosed space. Checking with the responsible building authority before purchase or construction is therefore essential and can save you fines of up to €50,000. Also note the regulations on boundary development. As a rule, carports may be erected directly on the property boundary if they do not exceed certain dimensions (e.g. a maximum length of nine metres along one boundary). Our expert tip: Get your neighbour’s written consent, even if it is not legally required. This can help avoid later conflicts. A look at your local development plan will provide information on any further local requirements. With solid planning for your home and living space, you’re on safe ground. Once the carport is in place, the question becomes the right protection.
Securing your investment: the right insurance cover for your carport and its contents
A newly built carport with a shed must be properly insured. The structure itself is usually covered by buildings insurance. Notify your insurer of the new build without delay to ensure cover. This can increase the annual premium by 20 to 50 euros. The contents of the shed, such as tools or bicycles, fall under contents insurance. Check your policy to see whether outbuildings are explicitly included. It is important that the shed can be locked so that cover against burglary applies. Insurance cover typically includes damage caused by:
Fire
Storm (from wind force eight)
Hail
Escape of water
Burglary (contents only)
A good level of cover is part of any well-thought-out property financing. Our independent advice helps you find the right tariffs. With the right financing and insurance, nothing stands in the way of your project.
Your path to a new carport: a step-by-step guide
From the first idea to the finished carport, it only takes a few well-planned steps. A systematic approach helps save time and money. The entire process typically takes between four and twelve weeks from planning to completion. Start with a detailed cost breakdown that includes a buffer of at least 15 per cent for unforeseen expenses. Obtain at least three comparison quotes for materials and tradespeople. Use an online construction finance calculator to compare initial terms. Bear in mind that even a smaller project such as a carport can increase the value of your property by up to five per cent. With the right preparation, your building project will be a complete success.

FAQ
Can I get government subsidies for a carport?
Direct subsidies for a carport alone are rare. However, funding may be available if the construction is part of a larger measure, such as the installation of a wallbox with a photovoltaic system (e.g. via the currently paused KfW programme 442). Also check your local authority’s subsidy programmes.
How long does the financing and construction of a carport take?
Approval for an instalment or home improvement loan is often granted within just a few days. The total project duration, from planning through any required approval to completion of the construction, typically takes four to twelve weeks.
What happens if I build without a building permit?
If you build a carport that requires planning permission without obtaining permission, the building authority can impose a fine and order the demolition of the structure. Fines can amount to several tens of thousands of euros, depending on the federal state.
Does a carport increase the value of my property?
Yes, a high-quality carport with a storage shed can increase a property's value. It is seen as a useful extension and protection for vehicles, which is an attractive feature for potential buyers and can increase the sale price by up to five per cent.
